I remember a couple of unhappy customers here in Sweden buying 'Kushi Maya' from H.W.Hyde & Son some years back when it was new and expensive. Bulbs apparently had rot issues, bloomed okay, but returned with very weak shoots the following year. One of the buyers had no problem growing L. nepalense, (I assume with rain cover for autumn/winter) so I don't think one could blame the buyer here, as he obviously knew what he was doing. Rather there were probably some bad bulbs around at that time.
