conditions that start bulbs into growth.

Dear All:

Arnold's comments and questions are thought provoking. While in Normandy
earlier this year, I noted Ipheion uniflorum in flower. On my return a
few days later to California, I noted the same species in flower in my
garden. There is a great deal of difference between the climate in
Normandy and California, in temperature, rainfall, and California is far
south of Normandy. Just what controls the flowering in such a case is an
enigma. Could it be the needed chemical changes in the bulb to trigger
flowering is a question simply of time needed for such to take place? I
can not think of any other logical reason. While in Normandy earlier in
the year, there were very hard frosts, the ground was frozen, while in
California we had no frost. The only climatical factor which might have
been more or less the same was the amount of rainfall enjoyed. But such
would not have warmed the soils to the same temperatures. So much to
learn, so little time! Cheers, John E. Bryan
