Big Blue Sea Holly

Plant in spring or fall in average to lean, well-drained to dry soil. Space 18–24 inches apart. Water thoroughly after planting. Avoid rich, moist soils- lean conditions produce the best color and sturdiest growth.

Water regularly during the first season to establish, then reduce significantly- established plants are highly drought tolerant. Avoid transplanting once established, as this plant has a deep taproot and resents disturbance. Deadhead to extend bloom, or leave the dried flower heads for spectacular winter structure. Cut back dead foliage in early spring. Largely pest- and disease-free and deer resistant.
