This is a heavy blooming easily grown perennial with a lavender blue color that is almost indescribable. It blooms from May through September on strong stems, especially if spent blooms are removed regularly. It grows 12–15" in height, prefers moist, well-drained, neutral to alkaline soil, and is useful in the border or as a cut flower. Another guaranteed butterfly-magnet.
Height: 12 - 15 in
