Nursery contributed plant descriptions

Blue green stems with masses of small metallic blue flower heads on tall 4' stems. As with all Sea Holly, a very attractive cut flower.
An explosion of intense, metallic-blue flower heads are borne on wiry stems Summer-Fall on this 3’ tall & 1 foot wide sun-loving perennial. Graham Thomas calls it “an extremely effective garden plant.” Effective & pretty! For a eye-popping, color-contrasting combo, plant in front of Tanacetum parthenium aurea. Pow! Long-lasting cut flowers - fresh or dried. Average to sandy soil is best. Durable.
