Sea Holly Seeds

Sea holly's sheen in metallic blue and silver makes it visible at dusk as you stroll your summer borders. Perfectly matched with drier areas, and popular for xeriscaping, gravel gardens, plus more fertile perennial borders. Sprinkle some fine gravel around the crowns to allow proper drainage during wintertime. A biennial to short lived perennial that self-sows, sometimes too abundantly–cut most to the ground after flowering.
