Propagation and Care

Iris 'Louisiana Sea Wisp' can be propagated by division or seed. Division is the most effective method and is best performed in early spring or late summer. To propagate, carefully lift the rhizomes, divide them into sections with roots and shoots, and replant them in suitable moist conditions.

Once established, this plant requires minimal care. Regular watering is essential to maintain the damp conditions it prefers. Deadheading spent flowers keeps the plant tidy and may encourage prolonged blooming. Cutting back old foliage in late autumn prepares the plant for winter dormancy and encourages fresh growth in spring.
