Some years, they don't bloom. I'm just back from a week and a half of attempted fieldwork in Nevada, with a hiatus to Southern California for a lecture to a Desert Institute class. Very few Joshua trees were in flower, so the trip was kind of a bust. But it was still good to get out into the desert. The weather was only really cold a couple nights, and almost too warm in Palm Springs. When I drove back into Moscow this afternoon, it was snowing.
