Blue Queen Salvia, 15-18", rich violet-blue salvia. This garden-favorite perennial is a member of the mint family, performing well and blooming brilliantly with a lovely fragrance. Butterflies love it as well. Heat- and drought-resistant hybrid explodes with plump spikes in midsummer. Flowers have long staying power well into fall. It is an excellent choice for cut-flower arrangements, and can be dried as well. Salvia is easy to care for with a good resistance to pests and disease.
