Eryngo Overview

The genus Eryngium contains around 241 biennial and perennials, with some evergreen species, also called eryngo, amethyst sea holly and sea holly. These are typically grown for their flowers and foliage and originate from dry, rocky habitats. They possess long tap or fibrous roots and oval to heart-shaped, sometimes divided foliage. Foliage is spiny and may be silvery in colour, ranging to white or blue-green. Flowers resemble thistles and are white or blue, surrounded by showy, spikey modified leaves known as bracts. This genus contains popular ornamental species and many hybrids have been produced for garden use.
