Eryngium ovinum – Blue Devil

This is an interesting perennial which grows from late winter, flowers in summer with bright metallic blue interesting spiky heads, and then dies down in autumn. This spiky appearance gives the common name of Blue Devil, and they make great cut flowers, both fresh and dried. While the plant dies down, it is a relatively long lived perennial, having a good sized tap root. Needs a sunny spot in well drained soil, tolerates medium frosts. Grow from seed in summer.

Eryngium ovinum occurs in temperate woodlands and grasslands in NSW, Victoria, SA and WA.
