Acalanes Wildflowers

March 30, 2009

The rains were a little below normal this winter and most of the rainfall occurred in February and early March. Bloom times seem about normal. These are the wildflowers we saw along the creek and in the large meadow at the top of the Acalanes Open Space. We walked up the creek from the Sousa Drive entrance, followed the Briones-Mt. Diablo Trail to the multi-trail junction, crossed the middle of the meadow, and came back along the bottom. The flowers are listed by color.
