The potted tropical hibiscus tree is a popular plant across the US in the springtime. They find a home on front porches, out on back patios and decks.
Personally, I like to see the tropical Hibiscus grown as a tree. For tips on how to care for these colorful flowered beauties. Read on…
The flowers of several hibiscus species represent nations. Haiti lists the hibiscus as their national flower.
Hibiscus syriacus what we call the “Rose Of Sharon tree” is South Korea’s national flower, and Malaysia calls Hibiscus rosa-sinensis its national flower.
Hibiscus comes from the Mallow Family – Malvaceae – of which several hundred species make up this diverse group of plants found throughout the world.
What a difference a week can make. In the spring, the flowers start to pop on the Hibiscus trees. It is truly a beautiful sight to see thousands of tropical plants with red, pinks, oranges, and yellows all starting to bust out to show off their colorful flowers.
We’ll discuss – Florist Grade Hibiscus – briefly below and then look how to grow Hibiscus plants, the ones grown as small potted trees for patio or terrace color as well as potted specimens in front yard landscapes.
Read on for more Hibiscus plant information.
Growing Hibiscus Indoors In The Nursery
You’ll find “Florist Grade” hibiscus plants grown as flowering plant bushes in greenhouses. They display a deeper foliage color providing a dark background for the colorful flowers.
The outdoor/patio types are grown outside as bushes also, but we find a lot of Hibiscus trees grown or what are called “tree standards” produced outdoors.
Bush type hibiscus plants start life from cuttings. Most Hibiscus trees are started from air-layers. Air-layers are a commonly used propagation method for plant material (that is a whole story in itself).
Stock plants grow in the ground and reach a height of 6′-8′ feet tall. The branches are trimmed, removing the side branches making one long straight stem (which stays on the tree) about 36″ inches long. The base is then wrapped with sphagnum moss and foil to retain moisture.
Roots form and begin growing into the moss. These air-layers are removed from the stock plants and planted into containers. Each stock plant can produce 50 to 100 plants per year.
After planting the plants are trimmed, and shaped into forming a small Hibiscus tree. This process takes 12 months for a 10” plant. Some growers take 3 or 4 air-layers and braid them together.
How To Make A Braided Hibiscus Tree: Video
Over the past few years, I’ve seen many plants grown as a braided tree: Ficus, dwarf arboricola, even dracaena.
Why should a braided Hibiscus be any different?
The video below shows “How to braid” your own hibiscus tree. Beautiful flowers along with an interesting trunk.
Characteristics of the Outdoor/Patio Hibiscus Bush
The outdoor/patio tropical hibiscus tree is taller, more open, and has lighter colored leaves than those grown as ‘Florist Grade’.
The facilities producing the outdoor/patio type are:
- Outside growing areas (acres and acres)
- Overhead irrigation
- Some method to keep the plants from blowing over in the wind.
Hibiscus Tree Care
Placing your Hibiscus tree in full sun will produce the most flowers and best growth. Try to keep the plants out of windy areas.
Hibiscus plants will thrive outdoors where the night temperature doesn’t drop below 50 degrees. Hibiscus are used outdoors in tropical climate landscapes. Avoid excessive cold and hot areas.
It is important you keep the soil of the patio hibiscus plant moist at all times. Saturate the soil at each watering.
To test and see if you need to water, place your fingers on the top of the soil; if it feels dry to the touch, it is time to water your Hibiscus.
When growing outside water your plant at least 3 to 4 times a week.
Hibiscus requires plenty of water. However, they do not like to sit in water.
Plants like the root ball to be well watered, but avoid overwatering and allowing Hibiscus to sit with “wet feet.” To prevent root rot plants should drain completely drain after waterings.
Avoid using cold water, especially during winter months, when watering your hibiscus.
This tropical plant prefers water around 95 degrees. Always check the water temperature with your hand to ensure it is not too hot and never too cold.
Patio hibiscus plants respond well to balanced plant fertilizers like this.
If you want lots of flowers, you’re going to need to fertilize your potted hibiscus.
Select a balanced slow-release fertilizer such as a 20-20-20 or a specially formulated Hibiscus fertilizer.
Easy Hibiscus Trees Delivers Colorful Results
Given sunlight, moisture, good drainage and temperature which stays above 32° degrees Fahrenheit year-round, hibiscus will reward the grower with blossoms almost continuously but most prolifically during the summer and fall months.
Even in the north the gardener need not be without them. They make wonderful large pot plants for a sunny window and may be placed outdoors on the patio in full sun from spring to late summer.
Plants may set too many buds for the root development to support and some or all of the buds will fall for a time. Fertilizing and additional humus will usually take care of this.
Pruning Hibiscus Plants And Roots
Prune the branches of your hibiscus trees to maintain the desired shape. The only reason for trimming hibiscus or pruning Hibiscus is to encourage more flowers and keep the plant in balance. Pruning will also help to stimulate more growth and more shoots.
Learn more on –> Pruning Hibiscus
To keep your Hibiscus plant looking healthy, establish three to four main branches of the plant. Select the most sturdy and upright branches when pruning and allow those to become the main stems of the plant. Remove any weak or sideways growing branches.
When repotting, you may want to root prune the root ball. Remove any weak, sick looking or ailing roots gently but firmly. When pruning use the rule of thirds. Never prune more than one-third of the root or the plant. When in doubt, err on the side of caution and don’t remove it.
Hibiscus flowers open daily and last for only one day, after which they die. Your plants will probably have flowers which opened during transit, fallen off and started to rot.
This is normal! Simply remove all wilted or unsightly flowers and keep grooming daily.
While visiting your garden center keep this in mind. Hibiscus plants are heavy drinkers and aggressive feeders. Look for full plants with good color. I’ve never seen plants get the care they need during their brief visit at the garden center. They will probably need a good drink when they get to their home.
Hibiscus plants losing their bottom leaves can be a sign of the root ball not getting enough water and drying out, or plants being in transit too long.
The Hibiscus Plant Loves Lots of Sunshine
Plenty of sunshine is necessary to make hibiscus plants grow sturdy and to produce blooms. To insure good branching, pinch growing tips when small.
If the pinching is done just above an outside bud, the new growth will branch out into a desirable bush.
Hibiscus flowers are borne on the young wood, and a heavy pruning is in order every year so that plenty of new growth can develop without the bush becoming too large for indoor growing.
Hibiscus thrive under fluorescent grow light culture. Grow Hibiscus by placing plants under the tubes, so the top of the foliage does do not quite touch the tubes.
Hibiscus matensis, a species with variegated pink, silver and green leaves, has been known to thrive and flower all winter under fluorescent lights.
A fluorescent unit can be made of two 48″-watt tubes. Given much humidity and 12 to 15 hours daily illumination, Hibiscus does well under the lights.
Growing temperatures should range from 60 to 65 at night to 75 during the daytime.
How To Care For Patio Hibiscus Trees
A tall, bushy plant, three feet tall, will thrive in an eight-inch pot.
Hibiscus is not particular about soil or potting mix. It will combat root rot and nematodes best with plenty of humus added, and maintaining a neutral pH.
Soil with perfect drainage with a rich and humusy growing medium will yield excellent results. An African Violet soil like this is usually satisfactory for hibiscus.
Here is a recipe for hibiscus potting soil:
- 1 part garden loam
- 1 part Canadian peat moss
- 1 part fine bark and sand
Hibiscus use significant amounts of water, and outdoors during the hot summer plants may require watering every day. This free use of water quickly leaches out plant food in the soil. When fertilizing with liquid plant food, feeding is necessary every week.
A plant food with too much nitrogen will produce lots of foliage, and not enough flowers. A well-balanced food or special Hibiscus fertilizer will help plants produce large, well-colored blossoms, and in usual quantity.
If you purchase a plant that comes in a small pot and the leaves are rather banged and bruised, cut the top back partially to give the roots a momentary rest and then a chance to grow.
A plant without a good root system cannot be expected to continue to produce a floriferous plant.
Hibiscus Plant Propagation – Making Cuttings
Although the shrub first came from eastern Asia, it has proved its adaptability in subtropical areas where gardeners are enthusiastically searching for new types to add to known varieties.
The Hibiscus plant propagates easily from softwood cuttings or leaf bud cuttings from March to September. Use hardwood cuttings almost any time of the year. Many commercial growers propagate Hibiscus from air-layers.
Use a rooting medium of sand or peat moss and perlite, then treat the cuttings with rooting hormones. Or, if the grower is a green thumber, 6 to 8-inch lengths of stem with two or three leaves or half leaves at the top may be put into a bed which will be kept moist and, presto, they’ll grow and bloom.
The rooted cuttings then may be potted until they are transferred to larger containers or to permanent beds.
They will root in water, or they may be started in a moist mixture of peat moss and sand, or in vermiculite. When roots form, they should be potted into regular soil.
Cuttings rooted under fluorescent lights can be potted in six weeks’ time, and flowered in less than a year.
Grafting is done to secure blooms from rare varieties on older rootstock more vigorous than its own. If grafting fascinates you, graft five or six Hibiscus varieties onto one root stock.
Growing The Hibiscus Plant From Seed
Hibiscus seeds are large enough to handle easily, and blossoms come in about 18 months. Plants seeds in vermiculite, peat moss, or sand – best of all, a mixture of the three.
To set seeds on a plant, simply place loose pollen from one bloom into the little pads of stigma at the top of the pistular column of another bloom.
All varieties are not fertile, but a little experimenting will teach which ones will set seed. You can purchase Hibiscus seeds here.
Winter Protection Of Hibiscus
When temperatures dip to the 30’s hibiscus may freeze to the ground. In such cases it may recover slowly or not at all.
Plants may be covered and protected. Sudden changes in temperature are not easy to meet since warm days are interrupted by chilling, blustery north winds called “northers.”
The Hibiscus plant thrives outdoors in the summer. When moving them outdoors in May or June, thin out weak wood and prune to make the plant as shapely as possible. Keep the plant in partial shade to acclimate.
How To Overwinter Tropical Hibiscus Indoors
Move your hibiscus indoors before the first fall frost.
Before moving your hibiscus plant indoors check it over for any potential insects like whitefly, spider mite and mealybugs.
Learn more on controlling Hibiscus Whiteflies
Personally, I would give the plant a thorough spraying with Neem oil making sure to get the underside of the leaves.
Once you move your hibiscus indoors DO NOT get upset if your plant starts losing all of its leaves. Leaf loss is normal with reduced light levels. New growth will soon.
While overwintering your hibiscus indoors provide as much bright light as possible, along with warm temperatures.
Keep the root ball soil moist, but DO NOT allow the plant to stand in water.
In late winter, prune back all the leggy growth and start fertilizing with a well-balanced liquid fertilizer every two weeks.
It is recommended in the spring to repot your hibiscus tree in a good quality, well-drained soil and apply a balanced slow-release fertilizer.
Once all danger of frost passes in the spring, begin to slowly acclimate your hibiscus plant to the outdoors.
Using Hibiscus Bush & Trees As Landscape, Hedge and Foundation Plantings
When used as a hedge Hibiscus may be kept trimmed for a semi-formal look but will produce few blooms. Planting Hibiscus in clumps looks most attractive.
Hibiscus make fine specimen plants but are not well suited for foundation planting, especially if the landscaping plan calls for formal or semi-formal design. Plant them along the sides or the back of a house where a tall plant is needed.
When used in this way near the house, most homeowners cut them to two feet or less in height late each fall or cut back the older wood to the ground.
If not done many Hibiscus varieties grow too large for the average house. Take your pruners (we love our Felco #2 for pruning) and cut back the older wood. This does not decrease bloom since hibiscus flowers on new wood.
With no standardized names for hibiscus varieties, especially in the newer hybrids, a name may prevail in one section of the country for a red and to a yellow in another area.
If you’re looking for a particular variety the safest method, unless you see the blooming plants in a nursery, is to beg a cutting from a friend, who has the variety.
Hibiscus Flowers Alone Deliver Garden Color Interest Indoors
These brilliant plants add color interest to the garden and are equally useful as cut flowers.
Gather blooms without foliage to use in a cluster on a mirror or tray, or to string along some willowy bamboo straws or palm ribs to add tropical charm to daytime decorations.
Cut flower buds early, on the morning they are to open, and placed in the refrigerator until a few hours before they are to being used. Brought into the light they will open and hold their beauty for almost the twelve hours nature intended for them.
This method “tricks” them into evening use. They give a wide choice in color from white through delicate pinks, yellows, peach hibiscus, and lavender tints, to the most brilliant red and orange shades.
In Mexico, these and other hibiscus or mallows are called Tulipan. Down in southern Texas, Hibiscus syriacus is known as althea, Hibiscus palustris (moscheutos) is mallow, rose mallow or Mexican Hibiscus and Hibiscus mutabilis is Confederate rose or flower-for-a-day. The hibiscus is the only one called by its genus name.
The hibiscus is known as shoe-black plant in China because of the use made of a dye from the petals. It is said that the flowers can be rubbed on shoes in place of shoe polish when one needs a shine.
The botanical name, Hibiscus rosa-sinensis, or rose of China elevates it above this association with us.
Vibrant and Colorful Hibiscus Tree
I do not think I have ever seen a hibiscus with a flower that was not colorful and vibrant. You can select from reds, maroon to rosy red, pinks, lavender and white shades along with orange tones such as the orange Hibiscus.
Each grower who specializes in hibiscus can add names to the list, and each collector will continue to admire new hues and search for new types. “Hibiscus-mania” is developing rapidly and growers are not always able to supply the demand for newer types.
Other hibiscus grow in the south, but die to the ground in the winter or loose their leaves.
Northern gardeners who grow these shrubs in pots move them inside during the winter. Pot and tub grown plants cannot develop to outdoor size and beauty except under special conditions.
The hibiscus will continue to be a shrub for the extreme south and an increasingly popular one.
The hibiscus is of the shoe-flower family, and closely related to hollyhock plants, the Rose of Sharon, okra, and cotton.
Control Hibiscus Pests – The Usual Suspects
There was a big outbreak of whiteflies a few years ago which commercial growers experienced.
For all these hibiscus insect pests – mealybugs, aphids, thrips, spider mites, scale insects and whiteflies, treat first with a Neem all-natural pesticide oil or one of the insecticidal houseplant sprays.
Organic Neem OIl 100% Pure Cold Pressed – (16 oz) – OMRI Listed for Organic Use Neem Oil is our FAVORITE natural organic insecticide. Control aphids, mealybugs, plant scale and more. It can also be used as a soil drench.
Use Neem to control aphids on hibiscus which normally attack new growth.
Red spiders hate high humidity which hibiscus need to thrive. Neem oil will help control spider mites on hibiscus.
More Details on how to get rid of spider mites on hibiscus and many other plants.
Expect multiple spray applications at 5-7 day intervals for control.
Get rid of mealybugs on hibiscus with a neem spray, or for small infestations dab them with alcohol.
Weekly spraying with tepid water keeps the foliage clean and attractive.

Hardy Hibiscus Plants: Growing The Perennial Hibiscus
So far in this article, most of the discussion has centered on the tropical hibiscus from the family Malvaceae sometimes called the Chinese hibiscus.
However, there are many other varieties of Hibiscus. Another favorite group is the perennial hibiscus called the “Hardy Hibiscus.”
The rose mallow – Hibiscus moscheutos is every bit as glamorous as its tropical relative but hardy enough to survive quite cold winters.
Know for their delicate textures, pure shining colors, and enormous flower size (10″-12″ inches) makes these giant hibiscus true show-offs in a summer garden.
Spectacular as specimens in a perennial border, or grown as a hedge or screen.
Hardy types of hibiscus over the years have been developed for many climates and are suitable for Northern gardens. They increase in beauty with each seasons growth.
A well-grown one with a dozen or more nine- to 12-inch saucer-like flowers at a time is enough to stop traffic! For an added blessing, these beauties are easy to grow.
Hibiscus moscheutos is native to coastal areas from Virginia north and is sometimes found near marshes and inland ponds as far west as Illinois.
It is sometimes known as the swamp rose mallow or sea hollyhock and is a large perennial herb with oval leaves, pubescent beneath.
Through hybridizing the rose mallow hybrids (e.g. Hibiscus Midnight Marvel) do well in drier situations than might be expected since the species is typically found in marshy conditions only.
They prefer a light soil well supplied with humus. Periodic application of a complete fertilizer is helpful. Give them no lime they prefer a slightly acid soil.
These sensational flowers of enormous size and breathtaking beauty can measure 10″ to 12″ inches across and are in full flower from July until heavy frost.
The plants grow 5 to 6 feet tall with a shrub-like appearance when fully grown in July. Use them in place of shrubs, or grow them massed with plenty of space for them to develop.
They make an ideal quick growing screen and be spaced 3 to 4 feet apart for proper development. The large green leaves are an added attraction.
This mallow family member looks like a scaled down hibiscus rosa-sinensis. Introduced to the US garden trade in 1985, This “mini-hibiscus” is a bushy plant growing to roughly 18″-20″ inches. It is grown as an annual hibiscus producing lots of blooms of deep-red hibiscus flowers, or pink with white throats.
The term “Abelmoschus” means “musky-seeded,” and this native of India finds its seeds used in the perfume industry.
When growing from seed, plant indoors in March and expect blooms somewhere around 100 days later.
Abelmoschus will handle full sun but does better with some shade.
Hibiscus Tree Care Plant Trivia, Questions & Answers
TRIVIA: Did you know that Hibiscus rosa-sinensis is the national flower of Malaysia?
At one time the famous “Hawaiian lei” was made only of green material until the brilliance of hibiscus bloom impelled the bronze-skinned maids to add color to these tokens of friendship.
Rosa-sinensis have numerous medical uses. It is also grown as an ornamental plant. Women in some countries use it for hair care purposes. Children in the Philippines use it for their bubble-making game.
The sepals of Hibiscus sabdariffa are used to make hibiscus tea.
In fact, George Washington ordered hibiscus from Philadelphia nurseryman John Bartram in 1792. These plants had single, red flowers, similar to the present day variety.
Both the flowers and leaves of the Hibiscus bush can be used to produce a lovely reddish Hibiscus dye. [source]
The seed oil of Roselle (Hibiscus sabdariffa) is a rich source of gamma-tocopherol. [source]
Question: A hibiscus plant along with the Cordyline (aka Hawaiian ti plant) are a couple of the plants we brought back from our Hawaiian vacation. Can Hibiscus be grown indoors? We also saw small hibiscus trees that were interesting but like the bush type much better. Can hibiscus be grown outdoors in a pot on a patio or deck? Courtney, Nashville, Tennessee
Answer: Hawaii and Hibiscus – picturesque words bringing to mind a vision of sunny skies and hula dancers adorning their dark tresses, exotic blossoms and tropical climate.
Hibiscus Tree Care – Dropping Buds or Blooms?
Question: Why do the flower buds and Chinese hibiscus leaves turn yellow and drop off before blooming time? RR, CA
Answer: Perhaps there is something wrong with the location of your hibiscus. It should have good light and a well-drained soil.
The hibiscus (hy-BIS-kus) lends itself beautifully to pot culture, and because there is no dormant season for the potted plant, it may be kept in bloom the year around.
It ranks high in popularity along the Gulf Coast in Florida and Texas and in Southern California as well as a colorful springtime plant for the northern patio.
Hibiscus Plant Not Blooming?
Question: My three-year-old Hibiscus rosa-chinensis didn’t bloom this year. Early in the spring I root-pruned it and used a systemic fertilizer spike for fertilizer and aphid control. The plant is healthy and growing well on the northeast side of the house. It is moved inside for the winter, during which time it usually sets buds for spring. Pulaski, Tenn.
Answer: Because your plant sets flower buds during the winter, it is doubtful that spring root-pruning or the spike was involved.
However, many potted plants refuse to flower after root-pruning until they have refilled the pots with new roots. It is a good idea to keep a hibiscus pot bound to help control its overall size. Hibiscus is a “long day” plant, that is, it needs at least 14 hours of light daily in order to set flower buds.
If it spends the winter in a room where the lights are turned off early in the evening, consider getting a plant light and timer for it.
Check the label on the spike’s container for nitrogen content. If the percentage is high, the plant is being forced into vegetative growth at the expense of flowering.
During its growth period, feed it monthly with a mild liquid fertilizer, something like 5-10-5 at one-half strength. It should do well in a standard potting mix with good drainage, generous watering except during dormancy, warm temperatures (55 to 60 degrees Fahrenheit at night in the winter), and lots of good, bright light.
The “Talk” Of Hibiscus Plants 60 Years Ago
I always find it interesting how plants we think of as “new” happen to find their way back into popularity over time. Like many other plants, the Hibiscus is no different.
Here’s how the humble Hibiscus found themselves described back in January 1956 from the pages of Horticulture Magazine titled:
Hibiscus Bush In Hawaii
Thirty-three years ago, the lovely hibiscus was officially proclaimed the flower emblem of the Territory of Hawaii. It was described as “a beautiful, indigenous blossom which grows luxuriously on all the islands, appearing to be most generally representative, no other flower having so great a variety of color, of form or such continuous bloom.”
It literally grows everywhere, tumbling in cascades of bright bloom colors over verandas, on the tops of lava rock walls, as hedges, windbreaks and screens and most effectively as a specimen plant in gardens. Every yard boasts at least one hibiscus, which may vary in height from a good-sized herbaceous plant to a big scale shrub or small tree, 20 feet high. The wide variety of color and form and the case with which it grows accounts for its popularity.
Since hybridizing of these spectacular flowers is easy, both single and double varieties appear in all hues but blue. They range from clear white through palest pink and yellow to bright orange or gold, as well as glowing scarlet, deepening to rich tones of dark crimson. In recent years, hybrids have been produced with several hues to a single flower, but some of these polychromes are more interesting than beautiful. The large pinks with stamens modified into petals suggest old-fashioned cabbage roses or peonies.
Individually, the flowers resemble those of its relative the hollyhock. They open at dawn, remain crisp and fresh for a single day and close suddenly at nightfall, whether left on the shrub, picked and put in water or laid out dry on a table. Since fresh buds open every day, the hibiscus blooms on the islands throughout the year.
Hawaiian women wear the blossoms in their hair, a charming substitute for earrings, while men tuck one over an ear at festivals. Blooms in profusion are strewn down the length of leaf-covered tables, prepared for native feasts, or laid out in colorful array on counters in the island banks. They vary in size from an inch across, to hybrid giants, a foot wide. Some are ornately ruffled. Actually, the larger ones are almost artificial in appearance.
A sacred flower with the early Polynesians, many references to the hibiscus can be found in their ancient mythology and folk lore. Six or seven species native to Hawaii have been found. A native white form (Hibiscus arnouianus) flourished in isolated areas on Oahu and Molokai for many years, until it produced varieties which now appear quite different from each other. These whites are the only kinds with fragrance and they remain open longer, sometimes lasting three days. Both these characteristics, sought by hybridists, are apparently difficult to transmit in crossing.
The common red hibiscus or China rose (Hibiscus rosa-sinensis) of Asiatic origin has the greatest number of variants botanically and is the species used most frequently for hedges.
The pink hibiscus (Hibiscus cameroni) from Madagascar is also a common hedge plant on the islands. Deep pink with a white area near the base of each petal, its attractive, wide spreading flower is larger than that of the common red. It is used frequently in crossing since the plant is vigorous, well branched and abundant in foliage.
The coral hibiscus (Hibiscus schizopetalus) differs from the others, bearing a small blossom with strongly-recurved, deeply-fringed petals. The staminal column is long and conspicuous, and swings like a pendulum in the breeze. A tall, slender plant, almost vine-like, it has small, delicate leaves. The weight of the flower, on its very slender stem, causes it to fall over and hang in bell-like fashion. This parent of many of the island hybrids imparts to them its grace, its lengthened staminal column and its frilled petals. Coral hibiscus is frequently used to make arbors, since its slender branches can be trained easily to cover a support.
Fifty Years of Hybridizing
Keen interest in hibiscus culture on the islands began about the turn of the century, when Walter M. Gifford began crossing strains. Enthusiasm spread and as the island people traveled they sent or brought home new varieties. In 1914, A. Gerrit Wilder held the first hibiscus show where he exhibited some 400 kinds. During the years that followed, amateur breeders found much pleasure in this fascinating pastime. Then Agricultural Experimental and Extension Services on the islands published literature on the subject for beginners. One grower claims to have produced over 2,700 distinct hybrid varieties.
Five is a magic number in the makeup of the hibiscus flower. There are five, stiff, papery 5-toothed staminals with a column rising in the center, five stamens and five lobes to its calyx. The stigma of five parts is usually a bright crystalline red, like a bit of coral at the top of the central staminal column. Stamens grow on the sides of the staminal column yellowing it with their pollen. Usually it is stiffly upright but sometimes it sweeps outward in a graceful curve, indicating that it is a hybrid and has the coral hibiscus in its ancestry.
The flowers lend themselves readily to hand pollination. Pollen of one flower is dabbed on the pistil of another after its own pollen has been removed. To keep the bees from in terfering, a bag is used to protect the newly made cross. Seeds ripen in about a month and, when planted, may be expected to bloom in about a year. The outcome is a suprise of mixed and unexpected characteristics. By careful selection some amazing hybrids have been produced. Since the seedlings vary greatly, both cuttings and grafts arc made to increase desired kinds.
In 1947 the late John A. Johnson, one of Hawaii’s leading hibiscus breeders and fanciers, gave his large collection to the University of Hawaii Experiment Station. From this collection, the University has selected some excellent new varieties for the market with special emphasis on the type of plant, its vigor and habit of growth, as well as the quality and color of the flowers.
Periodic pruning is important and at pruning time many new hibuscus plants are propagated by means of cuttings. This method is frequently used in planting new hedges. Varieties that do not root readily are multiplied by grafting, budding or layering.
From 400 varieties in 1902 more than 5,000 have been developed. Visitors to the islands are so fascinated by some of the varieties, they want to take hibiscus plants home with them, but quarantine regulations prohibit the shipment of cuttings or plants. However, seeds can be shipped. Some of the Hawaiian varieties are cultivated in greenhouses on the mainland and florists who have featured them have discovered they make popular, decorative house plants and have profited by growing them.
