During a trip to the Redwood Coast of California in August, 2014, the Redwood Sorrel flowers were in bloom. You sometimes see another type of sorrel growing in people's yards which you can recognize by the leaves, but this one is a wild species native to California. It grows in shady places under the big trees and up the coast into Washington state. This flower has 5 petals with purple veins and 10 stamens. Plants in the sorrel family, including Oxalis, have sour sap.
This Redwood Sorrel was blooming in the Sinkyone Wilderness State Park. We saw it during an overnight backpack trip where we camped near a beach. This part of California's coastline is the most remote coast in the state, even though the area used to have a large lumber operation that ceased operating many decades ago.
Remember, it's not just a picture, it's a story!
