Botanical illustration of Sweet Violet & Native Violets — Perennial · Viola sororia / odorata

Don't weed it — the humble violet is a keystone: the sole caterpillar host for the fritillary butterflies, an early bee flower, an edible (candied violets, violet syrup, salad flowers, vitamin C), and a pretty self-sowing shade groundcover. The native blue violet spreads into lawns and woods; the European sweet violet adds fragrance. A wildlife and culinary gem hiding in plain sight.

Often dismissed as a lawn weed, it's a keystone wildlife plant, an edible (candied violets, violet syrup, salad flowers), and a self-sowing shade carpet. The fragrant European sweet violet is the perfume/confectionery type.
