More Information About Eryngium

The common name, sea holly, refers to Eryngium maritinum, a coastal species whose leaves are holly-shaped. While there are many annuals and biennials in the genus Eryngium, we have chosen primarily the longer-lived species which are prized for their interesting foliage and alien-like flowers.

Although beautiful, these are not friendly plants. The leaves, bracts and flower petals are all covered with spines. If you are brave enough to cut one, eryngium flowers look wonderful in a vase.

Growing Conditions

Eryngium prefers full sun and a warm site. Most of the species we offer require dry, well-drained planting sites. They resent being disturbed once established.
