Collection: Eryngium planum Seeds | Flat Sea Holly | Perennial Cut Flower Seeds

Eryngium planum, commonly known as Flat Sea Holly, is a striking perennial prized for its architectural flower heads, strong stems and exceptional performance as both a fresh cut flower and dried flower. Our Eryngium planum seed collection includes professional varieties in beautiful steel-blue and silvery-white shades, ideal for cut flower gardens, floristry, perennial borders and pollinator-friendly planting.

Hardy, heat tolerant and well suited to sunny, well-drained gardens, Eryngium is especially valuable for bouquets and dried arrangements, as its distinctive flowers retain their shape and texture beautifully. Selected varieties, including Blue Glitter and White Glitter, can flower in the first year from seed without vernalization.
