Most Iris pumila comes from rather cold climates and
most require a cold
season to bloom although they will
grow in a warmer area. There is no
reason to be
adamant that cold is required for all Iris pumila
since
relatively few have been in cultivation and it
is possible that some may
not require the cold trigger
for flowering. It is likely that it would take
a lot
of experimentation to find a pumila that does not need
this. Many
hybrids are available that have erroneously
been called pumila. some of the
reblooming hybrids
such as 'Baby Blessed' may not need cold to
stimulate
bloom. The Iris lutescens (chameiris) may have clones
that
don't require cold to bloom. Our knowledge of
many of these plants is still
too scant to make
sweeping generalizations as hard rules. Ben Hager
had
developed pumila clones that would bloom in his
moderate climate of
Stockton California. He used these
for breeding. He said that it was
possible to find
plants that would be adapted to any climate if you
just
grew enough seed. I had been trying to get him to
register his warm climate
pumilas and I think he was
agreeable to the idea shortly before he died.
