That's very interesting.  As I recall from my grad school days there 50
years ago, it can get rather nippy in Berkeley in winter.

I'm not ready to try Haemanthus outdoors in the ground here in Indiana just
yet, but I think folks in zone 7 should look into this notion.  I'd suggest
trying Haemanthus montanus first.  If it survives a couple of winters, then
try things like albiflos (cheap and common), coccineus (relatively common),
and humilis hirsutus (probably pretty cold-hardy).

Plant the bulbs completely in the ground, with the tip of the bulb just at
or slightly below the ground surface.  I'd start off with them in a very
well-drained soil.
