Hardiness Zones: 5 to 9 Height: 4 ft Spread: 2 ft Type: herbaceous perennial Flowers: Blue
Comments: Azure Sage produces blue flowers and grows in any garden soil with full sun or partial shade. If grown in clay soils it may winter kill and so winter protection is suggested. Because the plant starts growth slowly in spring it may be advisable to mark its location. Staking is needed to keep it from falling over.
Propagation: Division is done in spring or October but plants are slow to recover. Cuttings 3 to 4 inches long may be taken in early summer. The seed germinates in 2 to 3 weeks at 68 to 86 degrees.
