Use and Management

Variegated ginger is an excellent specimen plant, but can also be used in containers. It will make a nice accent plant in a shrub border or by a building entrance. This perennial stands out in any landscape and will delight passersby.

Place this perennial in full sun or partial shade. It will perform well in moist, fertile soils that are well drained. Variegated ginger is not very drought tolerant, wilting badly in full summer sun without irrigation. A partial shaded location or regular irrigation prevents this. In cold areas in northern Florida, the stems of this plant will be frozen to the ground, but new shoots will reemerge in the spring.

The matted clumps of this plant can be divided for propagation. Dig the plant any time and break the clumps apart with your hands. The stems can be removed or left on the rhizome which can be planted in a new location.

Pests and Diseases

There are no pests or diseases of major concern. Mites are a minor problem.
