I just received a small bulb of Lilium poilanei and do not find much about it online. The wiki says it grows on cliffs so drainage is important, I potted it with perlite and bark fines and a little peat. It seems like somewhere that it likes some lime, but I could be wrong about that. What about hardiness? Would it be hardy to Z8 with mulch and dry soil? I would keep it in a pot if need be. Does anyone have any info on this lily? Thanks Frank
