Dense spikes of deep blue tubular flowers are produced from late spring to fall attracting a variety of pollinators including bees, butterflies, and low flying hummingbirds. Blue Bayou Agastache is a small to medium-sized herbaceous perennial with deep green fragrant foliage and excellent flower power. Reminiscent of Black Adder but in a more compact size that is better suited to small to medium sized container gardens as well as a long flowering addition to the sunny garden or landscape. Provide a full to mostly sunny location in a well-drained sandy soil for optimum vigor and flowering as well as the plant's longevity.
