Haemanthus Hardiness

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.
