Exuberance of oaks

This slideshow requires JavaScript.

Coast live oaks (Quercus agrifolia) seem to be delighting in the rainy spring–everywhere I go, trees are drenched in blossoms, a green-on-green superbloom that is just as exuberant as the wildflower displays (though much more subtle). If you start to notice them, like I have, what you are seeing are the showy male catkins. These start out pale when young and age to an olive-yellowish color; the female flowers are tiny, and hard to see even up close.

This vigorous bloom doesn’t necessarily mean that there will be a heavy acorn crop come fall, however–too much rain can suppress pollination if it comes at the wrong time.
