Early-blue violet, aka hooked-spur violet, is a diminutive groundcover capable of beautifying any corner of your garden. Each spring, its fragrant purple blooms won’t fail to delight – and can be a highly decorative addition to salads and baked goods. The foliage is composed of delicate heart-shaped leaves, often curled into cute little cups, and is a larval host plant to a number of endangered butterflies.
