Sea Holly, perfect for fish for Christmas.

For a delightfully different plant, look no further than the Eryngium agavifolium. Also named the Agave Leaved Sea Holly, this is an evergreen plant that has glossy, sword shaped leaves and beautiful pale green to white flower heads during the summer and autumn. The novice gardener will have no problem cultivating this plant, and the only thing you really need to spend time on is keeping it protected from frosts during the winter months. Great in a cottage garden, and often found as an interesting addition to cut flower arrangements.
