While in North Carolina I saw these beauties!
Delicately fragrant flowers are edible and make delightful garnishes. Very winter hardy and eager to self-sow in the shade of summer plants, violas are cheerful surprises in the cool months. Johnny-Jump Up is tricolored in bright purple, yellow and white. Violas will rebloom in fall if cut back in the heat of summer.
I wonder if there are butterflies somewhere in the world that look like these flowers?
