Eryngium-Flat Sea Holly

Propagating Eryngium or Flat Sea Holly is difficult because of its long tap root so if you want to give a go do it in the spring and make certain your shovel is down as deep as possible or you can take root cuttings. Eryngium is a semi-evergreen and it prefers well draining sandy soil but will also handle clay and will take drought. It blooms are blue to pink and flower from July until after frost and the blooms persist into winter so they can be used in dry flower arrangements, so prune the plant before new growth starts in the spring. The plant height averages 24"-36" and it attracts butterflies, but not deer.
