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.
