Anise Hyssop has flower spikes that burst with a myriad of tiny blooms that span the purple spectrum: from soft lavender to rich violet; the spikes can grow to be 3-6 inches long. It is easily grown and maintained in a small urban garden. Plants self-sow readily, but undesired seedlings are easy to pull.
This plant is in the mint family, though its aromatic leaves have a licorice-like (anise) scent. Anise hyssop can be enjoyed in salad dressings, herbal tea blends, and potpourri.
