I have grown it in Gainesville, FL (Zone 8A) in the partial shade of live oak (which probably kept frost crystals from settling on the foliage. It had temps as low as 26 F. It has to be dry to get those temps or they will rot, if winters in green house may even stay evergreen even though dry. Doug's image is different from the 3 forms I have seen...there is much more red on the tepals. Mine havbe only shown atinge of pink after a few days old. One form gets a magenta almost purplish near the center. Is the spidery one H. anazoldoii? I wonder many taxa out there that are part of H.evansiae? Kevin D. Preuss http://www.amaryllis-plus.com/
