Black Adder Agastache

A Breeze to Perennialize
Whether you're an agastache novice or you're already happily growing many varieties of this intriguing perennial, Black Adder is an excellent selection. It'll keep growing and blooming, even after other varieties have faded, producing lovely bottlebrush blooms from midsummer until early fall. Great news for beneficial pollinators, because it'll provide them nutrition when food is more scarce. Grab a couple blooms for a lovely anise-scented cut-flower bouquet, or dry them for a longer lasting indoor accent. Very easy to grow, drought tolerant and because of the fragrance, rarely pestered by hungry deer. Lovely in containers, or let this carefree perennial naturalize.
