The Bindweed Convolvulus plant belongs to the Convolvulaceae family and native to the Mediterranean area.
Convolvulus is pronounced [kon-VOLV-yoo-lus] and comes from the Latin “convolvere,” which means to twine around.
It’s a fitting name for the dwarf morning glory plant, as it can twine around other plants as it spreads along the ground.
The attractive convolvulus tricolor is a dwarf variety of the plant and often goes by the common name dwarf morning glory.
In some places, people call it field bindweed.
It’s a small plant, making it a perfect addition to a balcony or as edging for a flower bed.
To ensure that it has a full bloom, follow these convolvulus tricolor plant care tips.
Caring For The Bindweed Convolvulus Plant
Size and Growth
The dwarf morning glories don’t get very big, reaching close to one foot and spreading up to two feet.
The thin foliage spreads with trailing runners sending up shoots. The small leaves are narrow, pointed, and clustered along the stems.
Flowering and Fragrance
Convolvulus tricolor is an annual and grown for its attractive display of flowers. It blooms from the start of summer through the middle of fall.
The plant produces trumpet-like flowers typically a violet or deep purple color. They remain open throughout the day if the skies remain sunny.
When the buds first open, they release a sweet fragrance. As the season wears on, they give off a very faint scent.
Light and Temperature
The plant is recommended for USDA hardiness zones 8 to 11. It grows well in dryer, sandy regions and likes lots of sunlight.
Placing the plant in full sun to partial sun encourages better growth and longer blooms.
As an annual, you don’t need to worry about frost, but it grows best at temperatures in the mid-60s to upper-70s.
It should also be kept away from drafts if possible.
Watering and Feeding
The dwarf morning glories don’t need frequent watering. During warmer parts of the summer, check the soil every few days.
The rest of the year, the plant only needs watering about once per week.
TIP: If the petals start to curl, the plant isn’t getting enough water.
Liquid fertilizer may be added throughout the year, but not every time. Use the fertilizer every second or third watering.
Soil and Transplanting
Warm, well-drained soil is best for the dwarf morning glories.
Adding a little bit of sand to the soil also helps recreate the native conditions.
Transplanting isn’t necessary, as the plant dies at the end of the year.
The only reason to transplant is if the plant outgrows the initial pot or planter where the seedlings were grown.
Grooming and Maintenance
Grooming is another task that isn’t needed for the convolvulus tricolor unless it spreads too far in its current home.
When planted near other plants, the foliage may start to crowd out other plants.
If the stems start to grow around other plants, trim them back.

Propagating Bindweed Convolvulus
Propagate the plant from seeds. Allow the flowers to remain on the plant at the end of the season.
When the flowers wither and dry, collect the seeds for sowing the following spring.
In most regions, the seeds can be sown outdoors in early spring, unless there is a threat of frost.
Planter trays may also be used to sow the seeds indoors.
Use regular potting soil for trays or flats. Add two seeds to each hole.
After the seedlings begin to grow, remove the weakest one.
Plant seedlings started indoors out in the garden or in containers in May and June depending on climate.
If sowing the seeds outdoors, select a sunny area. After the seedlings sprout, thin them to eight inches apart.
Pests or Diseases Of Bind Weed
The dwarf bindweed morning glory is considered an invasive species in some regions, such as Australia.
The plant can crowd out vegetation, causing other plants to die out.
The plant is relatively easy to care for but can suffer from overwatering and underwatering.
If the leaves or flowers droop or curl, the plant needs more water.
If the leaves and petals develop whitish growth, the plant is likely getting too much water, leading to mildew growth.
Soil with better drainage may be needed or less water.
Sticky growth indicates a pest infestation. In most cases, an insecticide is needed to remove aphids or mealybugs from the ground morning glories.
For severe infestations, the plant may be lost.
If a severe infestation occurs at the end of the year, allow the last flowers to wither, so the seeds can be used for new plants the following spring.
Suggested Uses For Convolvulus
The ground morning glories deserve lots of sunlight. Grow them outdoors in a basket, planter, or window box.
If the plant is grown in a flower bed, avoid growing it too close to other flowers to reduce crowding.
