We've been having lots of rain and cool temperatures in Northern California and most days the Oxalis flowers do not open. Even though we sometimes have warmer days in September and October than in the summer, the Oxalis display is wonderful here that time of the year. And it is a time of year when a lot of other things aren't blooming after the long summer drought. There are still a number of species that would bloom if it were warmer (the forms of Oxalis purpurea, O. versicolor, and O. namaquana). Sometimes I have O. obtusa in bloom now, but something ate a lot of the leaves and they are just now growing new ones. After trying it several ways, I'm convinced that starting watering in August works the best for me. This list has taught me over the years that there is not a "right" way to grow bulbs. A lot of different methods can work. It's nice Andrew that you have so many in bloom. I suspect that Oxalis do much better in southern California than they do for me, but I'm still grateful that Diana Chapman's description of the dazzling flowers and Mike Mace's early sharing of excess bulbs introduced me to this genus.
