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. Paul Licht, Director Univ.
