Jim: Alocasia hypnosa was very marginal here in Z7b in a mild winter, so I'd consider it at best a Zone 8a/8b plant. It looks like new DNA will put it in a resurrected genus other than alocasia...see link below to the new phylogeny. It was fine in the same nursery potting soil that we used for everything else...no sitting in water required. http://umsl.edu/~renners/… Tony Avent Plant Delights Nursery @ Juniper Level Botanic Garden 9241 Sauls Road Raleigh, North Carolina 27603 USA Minimum Winter Temps 0-5 F Maximum Summer Temps 95-105F USDA Hardiness Zone 7b email email@example.com website http://www.plantdelights.com/ phone 919 772-4794 fax 919 772-4752 "I consider every plant hardy until I have killed it myself...at least three times" - Avent -----Original Message----- From: firstname.lastname@example.org [mailto:email@example.com] On Behalf Of James Waddick Sent: Wednesday, June 26, 2013 1:00 PM To: Pacific Bulb Society Subject: [pbs] Alocasia hypnosa Dear PBSer, I was lucky to get a tuber of Alocasia hypnosa (thanks Monica). It is growing well with a 2nd leaf just fully 'out'. I'd appreciate any experience growing this species in a cool climate where it does show full winter dormancy. Any experience wintering this in the ground in Zone 5 or 6 w/ mulching or other protection? Does it do better sitting in water? Full sun or some shade? Any other specifics of soil, ph , mix etc. Not much on the web yet about this relatively new species. So far so good. Best Jim W.
