Care and Culture of Sea Holly
Eryngium bourgatii
Sea Holly,Eryngium bourgatii is a very uniquely ornamental, perennial plant which is among the favorites of many varieties of butterfly. The prickly foliage of this plant is variegated green and white.
The steel blue, thistle like flowers form atop a two foot spike.
Sea Holly is hardy in USDA zones 4-8. Preferably, they should be planted in full sun and in a light, well draining soil where they will not need transplanting. The plant produces a long tap root which makes transplanting or division difficult, but also serves to make it very drought tolerant. If it becomes necessary to move your plant, they should be dug in the Fall, after the foliage has decayed down to ground level.
Propagation is best accomplished by seeds planted where they are to grow, a foot apart in the Fall, but germination is slow. New plants can also be started with root cuttings taken in early Spring and planted in light soil, 2 inches deep.
