An array of colorful flowers in full bloom on the Stonewall Panoramic Trail. There's still time to go out and see native poppies showing off their bright orange hues. Thanks to Jeff Martin for sending us the photo above taken in mid May, 2026.

As you venture outdoors this summer, take caution of the plants you touch. The photo above shows native Poison oak (Toxicodendron diversilobum) with berries. Although it looks harmless, the oils from every part of this plant can cause mild to severe skin irritations. Keep in mind: Leaves of three, let them be. If it’s hairy, it’s a berry. If it’s shiny, watch your hiney. Visit Calflora and Golden Gate National Parks Conservancy to learn more | Photo by Wyllie Clayson.
