Most info supplied by Craig Howe, who grows these in his Northern California garden - around 40 rainfall
mainly during winter, annual lows of 20F, often much lower ( recently, 1997/8 it was 13F, around -10C ). High
humidity all winter long, many sunny days but sometimes no sun for a couple of weeks. No guarantees for this
lot, however. Opuntias have been omitted.
