Violet and Yellow Wood-sorrel are brightening up corners of the gardens and the edges of the yard, but their blooms are only out in the sun. Afternoon-shaded areas will have the ‘lucky clovers’ closing up their flowers.
Wood-sorrel flowers close up in the afternoon shade or at nighttime and re-open in the sunshine.
Yellow wood sorrel, Oxalis europaea, flowers arise in clusters on flower stalks that are separate from the notched, clover-like leaflets.
As kids we pulled off the erect seed pods and ate them for a sour treat! The leaves are edible, too. Just add a few leaves to salads or make an iced tea from the steeped leaves, sweeten with honey or stevia and chill. The yellow or pink blossoms make great looking garnishes.
Violet wood-sorrel, Oxalis violacea, flowers seem to flare open their violet-pink petals.
