I stopped by the lupine patch today and noticed that the plants that were blooming earlier were wrappping up, but that some other plants were putting out blooms for the first time.
I wasn't surprised because no species does everything at the same time, but it was interesting that the blooming was somewhat asynchrous. It rained pretty hard this evening, so that could provide additional moisture to spur blooming. It has been dry and windy for the past few days, which is less encouraging.
