sea holly
Sea Holly (Eryngium) features very unique, steel blue spiky flowers that add a touch of whimsy to the garden! This profusely blooming summer perennial attracts bees and butterflies. It is perfect for the rock garden or native xeric landscapes, as it likes drier soil and warm, sunny sites. Good drainage is a must for these plants to overwinter so as not to get root rot.
