is R. purpurea the most vigorous species?
 my March seedlings are already 20 cm high! but they started slowly...

on the other hand, a species whose label I've lost (but fortunately you'll be there when it flowers ;D) sown last year is still only 7 cm high.
Véronique, in our garden R. purpurea is indeed the most vigorous specie.

Herman.

Do you grow any other hardy members of Zingiiberaceae?

I am in USDA zone 8b where temperatures almost never fall below 15F -9.4C.  Rainfall 50" 110 cm + but none  June-September.  We seldom get snow; but when it comes we get 30" overnight. Soil is sandy loam with a lot of humus.

Herman,

VERY NICE!  I'm growing 18 species in 4 genera; but they are all seedlings planted  from last year's and the previous year's exchanges.
