$ 6.79



Sea Holly Alpinum (Eryngium Alpinum Superbum) - Eryngium Alpinum Superbum is nothing short of fantastic and is easy to grow from Eryngium seeds. It is commonly known as Alpine Sea Holly, and it is one of the showiest Sea Holly plants available on the market. The metallic stems and large thistle-like flowers mature to an intense steel blue color from summer through fall.
An elegant species for the herbaceous border, Eryngium Sea Holly is perfect for exciting displays and for cutting. Eryngium plants have a long season of visual interest, even to the winter garden. The summer-blooming blossoms, which are actually soft-to-the-touch, harden to long-lasting cut flowers that are perfect for drying and preserving. Sea Holly can withstand severe frosts and is a tough plant for full sun in well drained, light soils. Alpine Sea Holly will also grow from flower seeds in partial shade, but prefers full sun. It is a deciduous, tap-rooted perennial that dislikes root disturbances, so it is best to start Eryngium seeds directly outdoors.
