Cottage Garden Perennial Blue Sea Holly Seeds

Cottage Garden Eryngium Planum or Sea Holly seed

A pretty herbaceous thistle-like flowering plant, 'Sea Holly' is a clump-forming hardy perennial which produces masses of rich blue Thistle like blooms around 2" in diameter and held at 2-3-feet.  

Perennial Eryngium blooms from June through to August and later in good years.   Tolerates most soil and situations and is drought tolerant

Sea Holly forms a low clump or mound around 18-inch tall and across. Does best without too much competition, so don't over crowd in mixed borders. Sea Holly can be left to stand and dries to brown lasting most of the early winter, looks great when frosted.

Great architectural value and well worth growing in a mixed cottage garden border.
