There is another possibility her, having to do with the interaction of
daylight hours and climate
warmth. Both of which have to work together for a plant to be
successful. I suspect that SDB should be able to be successful
anywhere TBs are sucessfull. I suspect the secret is to supliment the
light at the time it is warm enough for the plants to start growing
Anyone who wishes to try an experiment with this can contact me. The
plan is to send out 2 each of 10 cultivars of SDB. Twenty plants each,
to anyone willing to try this experiment. One of each of the 10 plants
to receive suplimental light, one each of the ten plants to grow in
natural daylight. Evaluate over two years. The mix of plants will
include daylight neutral and cyclic rebloomers . All I ask is for the
participamnts to pay for the shipping. That would be $10.00 per
package,. Plants are yours to keep at the end of the experiment.
I would expect rebloomers to do better then oncers in warmer climates..

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. Bob (
