Giant Hyssop (Agastache Mexicana Lavender Blue) – This herbaceous perennial is best grown in moderately fertile, well-drained soil which is kept on the dry side. Because Giant Hyssop is highly scented, it is an excellent attractant to hummingbirds and butterflies. Agastache Hyssop flower seeds can be sown indoors 6 – 8 weeks before the last frost, and it will establish quickly in the garden after being transplanted when frost danger has passed.
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.
