Yes, behind the times... Grown in the ground, do Calostemma tolerate any summer water at all? I killed my first one by leaving the pot outside in the shade during our warm summer (104 F / 40C and above for several months.) The next two I have kept alive by bringing into the house for the summer, but they don't bloom. We don't get a lot of summer rain and some mediterranean-climate plants don't mind the small amount we do get. Another problem I have is soil, or lack therof. My "garden soil" is rocks separated by traces of dust. Excellent drainage! Leo Martin Phoenix Arizona USA
