Giant Hyssop Lavender Blue Flower Seeds (Agastache Mexicana)

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 they will establish quickly in the garden after being transplanted when frost danger has passed.
