This charming garden annual blooms May to July with violet blue, pink, or white flowers. Plants grow from 1 to 3 feet tall, and about half as wide, and have green foliage. They are a lovely cut flower, though removing the spent blooms will limit its reseeding nature and deprive birds of much-enjoyed seeds.
Grow in well drained soil. Prefers a sandy or clay-loam mix, but can established in practically any soil that isn't too wet. Prefers full sun to a bit of shade - too much shade will cause the plant to flop. Butterflies enjoy the flowers; birds enjoy the seeds. An annual, it can reseed - a good or bad thing, depending on your gardening style.
