I wonder if UC Berkeley will have one this year, my shots are from 2007.
I just found this nice picture blog from their 2010 bloom, you have to scroll sideways to see them all. As you can see by the surrounding pots, they have at least 4 of them.

and another one

They hand pollinate them each time so that they can grow out more seeds. They take a long time to bloom, in that last link, that plant was raised from a seed from 1995 and bloomed for the first time in 2008. So if you ever get a chance to see one, it's worth it! I have gone twice and in person, it truly is an amazing plant!
