Eryngium or Sea Holly

Eryngium x zabelii, commonly called Sea Holly, Easily grown in dry, sandy, poor to moderately fertile, well-drained soils in full sun. Intensity of flower and bract colors is best in areas with full sun and cool nights. Tolerates poor soils and drought. Tall plants tend to sprawl, particularly if grown in moist fertile soils or in anything less than full sun. Deadhead flowers after bloom to retain good plant appearance. This is a tap-rooted plant that transplants poorly and is best left undisturbed once established
