Eryngium Bare Roots

About

Eryngium, often called sea holly, is a hardy perennial known for its unusual spiky flowers and cool blue tones. These plants add structure and texture to sunny borders, gravel gardens, and coastal planting areas. When grown from eryngium bare root plants, they settle into the soil quickly and return each year with stronger growth. Sea holly grows best in full sun and well-drained soil. Its metallic blue flower heads sit above spiny bracts and silvery foliage, giving the plant a distinctive look in the garden. Gardeners often choose eryngium because it copes well with dry conditions and exposed spots. The flowers also attract bees and butterflies, bringing useful pollinators into the garden through summer and early autumn.
