Take a piece of the Sanctuary home with you! All of our seeds are gathered from plants grown in our own biodynamic garden.

Blue Cap Sea Holly (Eryngium planum) has roundish upright basal leaves. The flowers appear as blue buttons dancing above the leaves. Sea Holly prefers dry, well-drained soil. Honeybee forage plant. At the Sanctuary, we have found Sea Holly does great with a bit of sand mixed into our loam soil before transplanting.
