Spring Beauty, Claytonia virginica, carpets this lawn a few miles down the road from my house.
Native to Eastern North America, its name honors Virginia botanist John Clayton (1694-1773).
To admire these tiny wildflowers properly, you have to get down on your knees.
Spring Beauty's leaves and flowers are also edible.
Please Note: I do not recommend eating wildflowers.
Bees and flies are the usual pollinators, but they may be visited by butterflies as well.
