I didn't end up acquiring any gesneriads from the west coast, but I did spot a bunch during my touring--although, just like last year's trip, I didn't spot as many as I would have expected. I missed the local chapter's annual plant sale by a few weeks, unfortunately.
I did spot some beautiful plants at nurseries and botanical gardens--but there were a lot more Agave and Aloe laying around.
I spent a good chunk of time looking for gesneriads planted in the Asia and South America sections at the University of California Botanical Garden at Berkeley, but I found only one Aeschynanthus sp.
After Asia and while skirting South America, I discovered a horticulturalist in the Old Roses area. We started chatting, and within minutes he was proudly showing me an almost-flowering Sinningia tubiflora patch--well, no, it wasn't a patch, it covered almost an entire hillside. Turns out, the Sinningia tubiflora I have growing in my community garden plot comes from his collection. Small world!
I didn't notice any other gesneriads, even though I followed the little stream through all of Asia and wandered through all the greenhouses. I didn't pick any up any of the gesneriads for sale at The Berkeley Botanical Garden, either, although I do think I got a nice haul.
