Hello all ~ I grew L. squamigera and L. sprengeri in Minnesota for many years. And this in Zone 4a. squamigera always bloomed every August, but sprengeri never did for me. I now understand that the latter probably wanted considerable water over the summer months (it got only what fell on it from the occasional thunderstorm) but squamigera took whatever came its way in stride, including near total summer dryness. I don't recall where I got the squamigera (they are still back there and bloom each year) but the sprengeri came from Winterthur. Some of both are now here in Oregon and perform well each year -- would that I were able to develop a lycoris with flowers of the solid electric blue that marks these two as unique. Since MN has such a severe climate, being able to fool "Mother Nature" was always great fun. She would occasionally get even by allowing little snow to fall over the Winter with its well below zero temperatures and that would usually get the tenderer stuff, even under the mulch.
