Costus arabicus variegata, or Variegated Spiral Ginger, is a small plant native to South America that typically grows 2-5 feet tall. It is an evergreen deciduous plant with beautiful pink to white or off-white flowers, which can be long blooming when kept in ideal conditions. The variegation of the leaves is very attractive and the spiraling stems of this ginger make it a great choice for adding movement to your garden.

Costus arabicus variegata should be grown in partial to full shade in moist soil and with regular moisture. It is tolerant of frost and can withstand temperatures as low as 30F for a short period of time, but cold hardiness depends on the age of the plant. Young plants are not cold hardy at all and should be protected from temperatures lower than 50F. In order to be successful in cold climates, container grown plants are the best option. When growing in a pot, the soil should be kept consistently moist, with regular fertilization and limited exposure to freezing temperatures.

In order to ensure that the plant remains healthy and vibrant, regular fertilization is required, especially during warm months. To help the plant retain moisture and to protect it from the extreme heat, mulch should also be used. Additionally, pruning may become necessary over time to keep the plant looking its best.

Costus arabicus variegata is suitable for growing in USDA Zones 9-11 and can be a beautiful addition to any garden. With some tender loving care, this variegated spiral ginger can give your garden the color and movement it needs to stand out.

Close related plant, but with yellow flowers - Costus vinosus, that is often confused with Costus erythrophyllus. Costus vinosus is very rare. It was described by Paul Maas in 1976 from a single collection in 1973. It is a very distinctive species with waxy leaves that have deep wine-red undersides and unique cup-shaped ligules making it very easy to recognize whether in flower or not. This species is threatened and rare in the wild and is sensitive to habitat change. Since the last collection record was ten years ago, it is possible that this species is extinct in the wild or very nearly so.

Mature plant cold hardy at least to 30s F for a short time

Costus igneus (Chamaecostus cuspidatus) is known as the insulin plant because it may help lower glucose levels for some people with diabetes. Researchers believe it can help lower blood sugar level.

The plant has large, fleshy, smooth turmeric-like spiral leaves that are dark green on top with light purple undersides. The undersides of these large, smooth, dark green leaves have light purple shade. The leaves are spirally arranged around the stem, forming attractive, arching clumps arising from underground rootstocks. The maximum height of these plants is about two feet. The flowers are orange in color, appear to be cone-like heads at the tips of branches. Flowering occurs during the warm months.

Grow Costus igneus in either full sun or partial shade. Costus igneus needs fertile soil, with plenty of moisture. Due to these requirements, it is often planted near water. It makes a nice aesthetic accent in landscaped shrub borders, where the orange flowers will contrast the greens of the shrub border. Planted on two to three foot centers, Costus igneus can act as a tall ground cover, and can help brighten a partially shaded location. Propagation is by division of the clumps, cuttings, or by separating the offsets or plantlets that form below the flower heads.

The species reproduces vegetative by rhizome and birds disperse seeds when they feed on the fruits. Costus products are sometimes called Costus comosus and are edible in nature. The flower petals are edible! The flower petals are quite sweet and nutritious. It's a lower grower and makes a great ground cover. The plant grows very quickly. It is cultivated in India for its use in traditional medicine and elsewhere as an ornamental. It thrives in sunny areas with a little shade. It is a rapid growing plant, that spreads from rhizomes that form attractive foliage around the original root stock.

Costus igneus does well planted in the ground year round in USDA zones 9-11, but is also very suitable for a container garden or above-ground planter. The plant is moderately tolerant of drought. The Insulin Plant makes a beautiful indoor or house plant, perfect for cascading down a wall.

In Siddha medicine, it is known as kostum. It is being cultivated in Kashmir and the Himalayan regions for its root. It is related to the gingers and was originally part of the family Zingiberaceae. But now the Costus species and their kin have been reclassified into their own family, Costaceae.

Studies suggest that Insulin Plant has antimicrobial, antidiabetic, antiproliferative, hepatoprotective properties. The plant is also traditionally used in Ayurvedic medicine for the treatment of diabetes. Recent research indicates that compounds within the Insulin plant help regulate blood sugar levels, supporting these traditional uses and claims. The plant does not actually contain insulin, which is a misnomer, and can lead to confusion. The blood sugar regulating effects of the plant are it's prominent medicinal value, and are currently being assessed by pharmaceutical companies for use in over the counter and prescription based diabetes treatments.

10 benefits of insulin plant:

- Helps to reduce high blood glucose level

- Improves digestion

- Reduces cholesterol level

- Increases energy level

- Promotes weight loss

- Good for skin health

- Prevents heart diseases
