About this variety

Sea Holly is a striking perennial with spiky, silvery-blue flowers. It attracts pollinators and adds bold texture to landscapes and fresh or dried arrangements.

+/- 25 Seeds

Grown organically.

Growing notes

Perennial. Sea Holly needs a cold period to germinate. Sow it outdoors in the fall, or place the seeds in a damp paper towel in the fridge for 3–4 weeks, then move them to a seedling tray and transplant once the seedlings are sturdy. Plant in full sun, spacing plants 12–18 inches apart. Sea Holly prefers well-drained soil, even poor or sandy, and is drought-tolerant once established. This hardy plant requires minimal maintenance and will return year after year.

Germination worked well but they didn't result in any growth once planted.

Hi Caroline, I'm sorry this crop didn't work for you. Sea holly is a perennial that puts its first year into a long taproot, so it often shows little growth above ground until its second season.

I love a perennial that flowers in the first year and these did wonderfully! I've cut some to dry for winter gifts.

Received my seeds very soon after ordering. Have winter sown some, and will be planting the the rest shortly inside. Can’t wait to see them blooming in my gardens. Thanks.
