Eryngium - Planum

Sea Holly Blue (Eryngium Planum) - Eryngium Planum, commonly called Sea Holly, has been grown from flower seeds in America since the 1800's. It can be propagated by division, flower seed and root cuttings. Almost all Eryngium make excellent cut flowers as well as flowers used for drying. The flowers keep their beautiful blue color after drying indoors. Harvest flowers when the entire flower heads and bracts turn blue.

Eryngium - Yuccifolium

Rattlesnake Master (Eryngium Yuccifolium) - This plant grows well in full sun and moist to slightly dry conditions. You can grow Rattlesnake Master in light shade; however, it will eventually become spindly in shadier conditions. Since it can be quite top heavy when in bloom, it may topple over in windy conditions if planted from flower seeds in areas that contain too much shade.
