This coast banksia (Banksia integrifolia) is one of two at 285 10th Avenue/Clement in the Richmond, and the largest that I know of in the city. This tree from the protea family is an Australian native, and is *way* too rare in San Francisco. It has spectacular protea-like pale yellow flowers, and seems to thrive in our climate. They're very hard to find, but I think the folks at Flora Grubb sourced these two, so if you're interested in buying one, you could try checking in there. (And if anyone finds a good source for these trees, please let me know.)
