Jamie seems to have had my experience in never turning seasons on any 
bulb.  All of the amaryllis A. belladonna, Hippeastrum and a Crinum) 
from South Africa and the Nerines from Australia seem to have adapted 
to both climates where I cultivate plants.  No flowering, but leafing 
out, the first year but sporadic flowering the second. Nerines are 
coming on now; the amaryllids finished blooming in September, but 
some of the Hippeastrum start quite early, say in May.

I'm not sure what the 'normal' bloom time is in the regions of origin 
for the bulbs I received.


Davis, California; Sacramento Valley, very hot dry summers , mild 
spring and fall; irrigation required (usually) from April through 

also on the Russian River, about 90 miles north of San Francisco, and 
7 miles inland  from the Pacific (warm summers, cooling fogs in the 
late afternoons and early mornings)
