This very popular ginger is known as the "tropical crocus" or sometimes as the "resurrection lily". It gets the name from the fact that the flowers arise from bare ground (from the rhizome) before the first hint of any foliage. It is the first sign of spring in the world of gingers. The flowers are cute orchid-like white with a purple throat. Everyone insists that these flowers are fragrant, but I have never been able to detect the fragrance.
The foliage is more upright than other Kaempferias. It grows to just under 2 ft. in my garden in filtered shade. It has an understated pattern on the upper side of the leaves and purplish undersides. The color and pattern fades somewhat as it matures but still makes an attractive groundcover.
Most references rate this as hardy to zone 8 and some to zone 7. Mike Bridges (former owner of Southern Perennials and Herbs) tested hardiness to 7-¦F. In colder areas the rhizomes could be lifted and stored in a cool garage or basement in slghtly dampened peat.
It should be grown in a well drained woodland soil with light applications of fertilizer if needed to stimulate vigorous growth.
