I'm pretty sure it does NOT need summer water. I saw it growing robustly in
semi-arid situations where there definitely is no rain in summer, and where
it was up on hills with no likelihood of underground water. I would be more
inclined to suspect predation. It can stand a few degrees of frost; it was
growing well in the botanical garden at Valparaiso, where I was told they
had experienced temperatures down to minus 4 Celsius (c. 25 F), and also
inland in the coast range where I assume there is a bit of frost.
