Delightful, cool, lavender-blue flowers bloom for weeks in late-spring to early summer on 2' high spikes. Bright-green, aromatic foliage makes a nice backdrop for the pretty blooms. These adaptable, easy-care perennials are good for hot areas and also for the coast. Perfect for cottage gardens, containers or borders, this beauty will bring in butterflies, hummingbirds and bees! Remove spent blooms to promote reblooming. S-M-D
