Eryngium Bare Roots

Eryngium, which is also known as Sea Holly, is a beautiful perennial that people appreciate for its bright, spiky flowers and silver-blue colours. The sea holly plant has a thistle-like look and an architectural shape that gives borders and gravel gardens texture, structure, and a modern touch. These hardy plants come with bare roots and grow swiftly. They come back year after year with even stronger growth.

This drought-resistant plant is often called seaholly. It does best in sunny, well-drained areas and is especially good for coastal and exposed gardens. The metallic-blue flower heads of eryngium not only look great all summer long, but they also attract bees and other pollinators, making them great for planting schemes that are good for wildlife.
