Hi Travis, That's a nice photo of the Brodiaea elegans. This species is blooming for me now too in great abundance after our almost normal rainfall year. In the drought there were few blooms so it probably either didn't show up or didn't last long enough to flower. It's not the last to bloom for me. A form of B. californica blooms later as does B. pallida. Brodiaea leptandra and B. coronaria bloom about the same time as B. elegans in my garden. The size of the flowers of these species is variable. Triteleia peduncularis is a species that can have a lot of flowers, but one year we discovered one in our area with just a few. There is a great variation in size of flowers and time of bloom in different locations for a lot of species in the Brodiaea complex so it is hard to generalize. On the wiki we have photos of Dichelostemma capitatum in different counties in California. Photographers didn't note the size of the flowers so it is impossible to compare the size of the plants in counties with differences in the amount and timing of rainfall. I saw some flowering on a recent trip in May, no doubt long after plants in other parts of the state had dried up and gone to seed. http://pacificbulbsociety.org/pbswiki/index.php/… When you grow the plants from seed from different locations, they often bloom at different times. This has been a fantastic year for Triteleia laxa, again after fewer flowers in the drought. Our local species has short small flowers and blooms into summer so it doesn't fit your hypothesis either. I grow some that are in bloom at the same time that are much larger. So they have maintained their genetic tendencies when grown in the same place. And there is a great variation in the shade of blue as well. For awhile I had some that were really large, but I've lost them. So that variety must have not liked my conditions. Also one of the subspecies of Triteleia ixioides that blooms for me the last when it usually has been dry for some time, months after some of the others, has the smallest flowers. It sounds like a good subject for a research paper, what determines the size of flowers of the same species in different areas.

The lack of rain in late spring and summer may have enabled B. elegans to have larger flowers by natural selection, while selective pressures may be responsible for keeping the flowers of D. capitatum relatively small. >
