One of the easiest and most rewarding perennials to grow from flower seeds! The award winning Agastache Mexicana is a tremendously long bloomer that produces lavender blue, bottle brush-like flowers on strong, upright stems from early summer to early fall. It is useful for adding a spot of color to the garden late in the season when many other plants are finished. The Hyssop plant has foliage that smells distinctly like black licorice when crushed. This species is also popular as a cut flower, and it dries well for use in dried arrangements.
