Judging from what I saw today, next weekend or two will be the peak of the wildflower season in the Bay Area. I saw plenty of clover on Redwood Retreat Road.
The downside with much of the area close to San Jose is there’s a lot of wild grass covering the flowers, especially after a wet winter.
That’s why the backside of Mt. Hamilton is worth the ride. There isn’t nearly as much grass, so the wildflowers have the ground to themselves.
