This sheep sorrel was found growing in the same little island of greenery that I found the sweet vernal grass in. The sheep sorrel was growing in a small patch and had small, arrow shaped leaves with smaller maroon flowers. This particular specimen had flowered at this point. This plant has edible leaves that taste like lemon. It is related to spinach, but should not be eaten in large amounts. It is considered an extremely noxious weed and is very hard to control.

This trillium ovatum was a common sight on the forest floor at this camp ground. It was surrounded by other similar plants, though this was the only one I could find that was flowering. It had large, oval shaped leaves and a striking large, purple flower with skinny petals. It is common in the western United States and often grows in the shade of western red cedars and bigleaf maples, as this specimen was.

This species of grass was growing in small patches in various places along the trail. This one in particular came from a small island of greenery in the middle of the gravel parking lot at the riparian zone. This grass is another invasive species native to California that was flowering at this time of year. It throws up white flower spikes that catch pollen.
