These Semp Kalinda, Rubellum and Oddity, I just got them last March 2014, so they have no winter growing here yet in my yard. These three are in that one rectangular container.
My Semp arachnoideum, one batch I got in March 2013, and another one in June 2013.
At the extreme, we get a few overnight lows of 21F, average at 39F and daytime high at 65 to 70F, during winter. But our past winter has been relatively dry, so am not too sure yet how they really do if it rains and get cold. We get the valley inversion here, so when it is cold, gets really cold, but no snow.
I find the arachs more sensitive to the heat, when I got them, they quickly bolted. The others are doing just fine, with Semp Kalinda being the most active in making babies.
