Costus dubius, the green grenade ginger, is a perennial, tropical, herbaceous plant from Africa. It grows from a rhizome, and has beehive type flowers that grow from the base of the plant. It can produce many flowers in spring and summer, and in good conditions these can form a carpet of flowers. It is not frost tolerant, so is good for tropical to sub-tropical areas, or frost free temperate cimates. It makes a good landscaping plant , as it has lush foliage. It can be grown as a large container plant.
Costus like free draining soils with plenty of organic matter. They like a part shaded position. Regular applications of fertiliser every 4-6 weeks, and regular watering will ensure good growth of the plant. Mulching of the plant will conserve soil moisture and will minimise weed competition.
