The UC Botanical Garden in Berkeley has a titan arum about to open. This
is the same plant, named Trudy, that bloomed in 2005. Trudy (or perhaps
I should say T-Rudy) provided pollin (fathered) the plant we had in 2007
which is the source of seedlings we now sell. T-Rudy reached 62in this
morning but still seems a few days away from opening. If you are in the
area and have never seen one of these (in bud or bloom), it's a must.
Check our website (http://botanicalgarden.berkeley.edu) for daily updates.
