Hyssop plants develop purple or blue flowers in the mid- to late summer. The clusters of small, fragrant flowers attract bees.
Hyssop stems are slender and firm. They grow to 3 feet on average and support leaves that grow on opposite sides of the stem.
Hyssop leaves are small and bright green with thin veins down the center and jagged edges. Shaped like teardrops, the leaves are edible and impart a minty flavor.
Hyssop is a dense perennial herb that grows in clusters.
Dried hyssop is olive green, similar in appearance to dried thyme or oregano. Dried hyssop will smell minty.
