This beautiful Kaempferia was collected in Laos over ten years ago and I bought it from the well known Thai ginger grower, Supranee Kongpitchayanond. It is probably a form of the species Kaempferia angustifolia.
It has very pretty striped foliage and dainty orchid-like flowers. It increases moderately well and will form a nice carpet in a few years.
As with all Kaempferias, it naturally goes dormant in fall, even in the tropics during the dry season, making it adaptable to growing in areas with winter freezing temperatures so long as the ground does not freeze deeply enough to affect the rhizomes. I have been growing it outdoors many years in my Tallahassee zone 8-B garden and it has always come back reliably in the spring, even in years with temperatures down in the teens.
It should be grown in well drained soil kept moist during active growth but not too wet especially during dormancy. I grow most of my Kaempferias in with limestone and find they grow better that way.
