Roscoea tibetica is the smallest Roscoea of the genus of the hardy gingers and is highly variable. Often mistaken in the trade with R. alpina and R. scillifolia. One easy way to distinguish it from R. alpina is after the seeds capsules, which in this case are forming at the ground level like shown in the image.
This one is not as tiny as the R. tibetica B-15 offered last year (didn’t set seeds this year) but still only up to 15 cm in flower.
For the collector of the Roscoea; you need a small trough or a nice nook in the rockery just for it. Best with light shade.
Germination: easy, with 1-2 months of cold-moist period, but I have also germinated seeds without stratification. It forms fleshy small roots that need good drainage and careful handling. Flowering starts after 2-3 years, depending on how well the root system develops.
