Nhu, so far the Amaryllis belladonna continue to survive against the wall in my school garden in Chappaqua NY despite two very harsh winters.  This winter the leaves didnt get very far before they were burnt back, but right now they are lush and green, so it can adapt to our climate provided the bulb doesnt get deeply frozen (hence the against the wall position).  Last summer they bloomed in August, I suspect they will do the same this year.  Last year the foliage didnt really die back until July.  IIRC I had two bulbs bloom last year out of several.

In NY where the first Crinum bulbispermum bloomed and is sending up a second spike.  Totally hardy here.

Subject: [pbs] Amaryllis belladonna blooming project - year 4

Dear bulbophiles,

The first Amaryllis belladonna of the season has popped in
Berkeley. This
is going to be an early year.

I'm continuing to collect data
for the blooming time for this species. This
would be the fourth annual email
that I have sent out to the group
requesting your help to collect data for a
project. The main goal is to
collect blooming time of Amaryllis belladonna to
determine what cause the
flowers to break dormancy and start growing.

So far
based on three year's data, the blooming time correlated with
temperature. I
would like to collect more data as it will support the
temperature hypothesis.
This is where you can help. Please visit the survey

Once you're there, just fill in the
blanks and that's it. Please feel free
to fill in as many times as you wish as
they continue to bloom or if you
see them elsewhere.

Thanks in advance for
your help!
