I grow mine outside all winter long and although it has never been killed, after three years where the actual minimum air temperature dropped below 0°C (-1 or -2°C) for several hours and the exposed parts all got killed, I now keep it next to the house where the air temperature never goes below freezing. Temperatures of 0°C don't seem to bother it. I have seen the same problem with Paramongaia; it loves chilly winter weather, but once the air itself is in the negative degrees C for several hours, the leaves turn brown. Most winter growers tolerate a few degrees below 0 no problem, but there are a few that are much more touchy about it in my experience, so I can't leave those way out in the open completely unprotected in case we get that one night where the temperature here happens to get downright freezing for a little while. (Apologies to all those who live Zones 9 and colder…) ;-) --Lee Poulsen Pasadena, California, USA - USDA Zone 10a Latitude 34°N, Altitude 1150 ft/350 m On Nov 25, 2011, at 3:49 PM, Jane McGary wrote: > > What I'd like to know is whether anyone has grown this plant where it > experienced some subfreezing temperatures.
