Agastache foeniculum (blue giant hyssop; syn. Agastache anethiodora (Nutt.) Britton) is a species of perennial plant in the mint family, (Lamiaceae). This plant is native to much of north-central and northern North America.[1]

Anise hyssop is in the same family as hyssop (the mint family Lamiaceae), but they are not closely related. Hyssop (Hyssopus) is a genus of about 10-12 species of herbaceous or semi-woody plants native from the east Mediterranean to central Asia.

The young growth in spring is very susceptible to slug damagek. The flowering plants are very attractive to bees and butterfliesk.

Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse for their first year. Plant out in late spring or early summer[K]. Division in spring. Fairly simple, if large divisions are used it is possible to plant them straight out into their permanent positions. Basal cuttings of young shoots in spring111. Harvest the young shoots when they are about 10 - 15cm tall and pot them up in a lightly shaded position in a greenhouse. They should root within 3 weeks and can be planted out in the summer or following spring.
