Eryngium planum Planting Seeds – Sea Holly Garden Flower Seeds

Product Description

Grow Sea Holly (Eryngium planum), a distinctive perennial known for its steel-blue flower heads, spiky bracts, and upright branching stems. Its striking color and architectural shape make it an attractive choice for sunny garden borders, gravel gardens, cottage gardens, and naturalistic landscapes.

Sea Holly grows best in full sun and well-drained soil. Water young plants regularly while they establish, then avoid keeping the soil consistently wet. Its unusual blooms add texture to mixed perennial beds and can also be used in fresh or dried floral arrangements. The flowers provide a useful source of interest for bees and other pollinators.
