Curcuma [KER-koo-muh] is an elegant perennial summer plant with over 100 species.

It belongs to the family Zingiberaceae (ginger), which consists of notable species such as Siam Tulip and turmeric.

Curcuma and its species are native to Southern China, Southeast Asia, Northern Australia, and New Guinea.

Reportedly, some species of the tropical plant are naturalized in warmer regions of the world such as Florida, Central America, tropical Africa, and several islands (Indian, Pacific Ocean, and Atlantic Oceans).

The term “Curcuma” is derived from the Sanskrit word Kunkuma, which means turmeric.

Linnaeus (a Swedish botanist and zoologist) originally named this summer ginger in 1753.

Since then, almost 130 species of the genus have been named and described so far.

However, descriptions of some of the tropical species have remained unclear.

The two widely-known Curcuma species are Curcuma longa of the ginger family and Curcuma zedoaria.

The common name of Curcuma longa is “common turmeric,” while Curcuma zedoaria is Curcumanown as “white turmeric” or “zedoary.”

Unlock the Secrets of Exotic Curcuma Plant Care

Taking care of the curcumin ginger plant is relatively easy. This includes providing proper curcuma ginger plant care to ensure healthy growth.

Size & Growth: Embrace Curcuma’s Vibrant Potential

The Curcuma gingers are small, outdoor plants. They do not spread and remain the same size throughout the season.

During mid-summer, dense spikes of clustered curcumin flowers grace the plant. These mildly fragrant flowers last for three weeks.

Once the flowering period is over, the turmeric becomes dormant.

The heat-loving turmeric is usually cultivated in nursery pots from rhizomes planted in early spring.

While cultivating rhizomes, make sure to plant them at a depth of 2″ – 4″ inches.

Potted plants must be set into the soil at the same level at which they typically grow in the pot.

Circuma can thrive and survive on their own. But they make a beautiful accent to flowers like evolvulus, blue salvia, and caladium.

When curcumas are grown with other flowers, they spike up to 18″ – 24″ inches in height.

Flowering & Fragrance: Revel in Curcuma Flower’s Aromatic Charm

Some curcuma species emerge before the foliage (hidden gingers), making the best summer cut flowers.

These small, summery curcuma ginger flower adorn the plant’s lengthy stems, which boast green, lance-shaped leaves with a mild scent.

They make for a gorgeous addition to garden beds, garden borders, and container gardens.

Light & Temperature: Create the Perfect Environment for Curcuma

Another aspect to consider when you care for circuma plant is the light requirements.

Curcuma plants thrive best in full sun as they stay moist and healthy in hot climatic conditions.

At times, the soil of these heat-tolerant plants may dry out in warm temperatures.

This usually happens due to a lack of watering.

In such a case, it is ideal to grow curcoma in partial shade and watering them daily.

These summer-loving plants prefer moist, well-drained soil full of organic matter like compost and humus.

For optimal performance, the soil must have a high clay content and organic matter before sowing the seeds.

The ideal temperature range for growing circuma is between 68° – 95° degrees Fahrenheit (20° – 35° C).

The plant suffers if the temperature drops below 50° degrees Fahrenheit (10° C).

Moreover, this plant will thrive in USDA hardiness zones 8 to 11.

Watering & Feeding: Nourish Your Curcuma Plant

Curcumas have intensive water needs, requiring well-drained and moist soil to grow.

Throughout the growing season, the soil must be moist. If an area doesn’t receive much rainfall, irrigation is required to maintain moisture.

Don’t hesitate to mist the foliage in dry weather, as it helps increase the humidity levels.

Fertilize in early spring or summer with any general-purpose fertilizer or 20-20-20 soluble fertilizer every month.

With proper fertilization, the plant produces lovely flowers, which are a sight to behold.

Every four or five days, touch the soil with a finger, and if it is dry down about 1½” – 2″ inches, water immediately.

Keep the soil damp, but avoid overdamping at all costs.

Moreover, you can add a lot of organic matter like clay or sand before planting for optimal growth performance and achieve a loamy soil consistency.
