How to Plant and Grow Sea Holly

Bee introduces how to plant

Plant Sea Holly Seeds: Sow seeds in 2 in. pots or cell packs, press into soil and barely cover. Needs light to germinate. Kept at 70° F., germination usually within 4 weeks. If not, put container inside a zip-lock bag and place in the refrigerator for 4 weeks. Return to 70° F. until germination occurs. Transplant Sea Holly 18-24 in. apart. See starting your seeds, for information on growing seedlings under lights.

Grow Sea Holly: Full sun. Sea Holly plants tolerate heat, drought, humidity and salt and prefer deep, sandy soils. Will tolerate any soil as long as drainage is good. Water weekly during hottest weather for best performance. Cut flowers are long lasting, fresh or dried. The intense blue color of the flowers are intensified by warm days, followed by cool nights. Flowers attract bees, hummingbirds and butterflies.
