I bought Anthyllis lehmanniana from a very enthused grower at the local rock garden society plant sale last spring. I planted it in a trough, where it proceeded to grow to about 10" in height - not quite what I had in mind for trough culture! My question is: Is this species usually considered suitable (i.e. small enough) for trough culture (assuming it was identified correctly)? I see the seeds sold by alpine gardening societies, but could anyone who is familiar with the plant advise, please? Thanks in advance. Lori
