They were probably in bad condition when you bought them, and you couldn't tell because of the fibrous coats. Oxalis adenophylla in nature grows in gently sloping screes, often in depressions where the snow lies late (the habitat favored by many Lewisia species too). I have had commercially purchased plants in the garden for many years, tucked into retaining walls where the drainage is very good, despite the extremely wet winters here with frequent frosts. The leaves emerge in spring. It is tolerant of summer water but does not require it. I wish we had access to the many color forms of this species that can be seen in a single population in nature. The common commercial form is pale pink, but you see everything from near-white to deep magenta in the Andes. Jane McGary Northwestern Oregon, USA (where it is snowing like crazy as I write)
