Description

Sweet fennel (Myrrhis odorata) is a perennial herb of the Apiaceae family, featuring finely dissected leaves and anise‑like fragrance. It is a rare herb in which almost all parts are edible, leaves, flowers, immature green seeds, and the thick root. It begins vigorous growth early in spring, often from mid‑April, and blooms with white umbels before many other herbs. It thrives best in partial shade under light trees or on the north side of a bed, tolerating cooler, moister sites well.

Care instructions

Plant Sweet fennel in humus‑rich, moderately moist soil in partial shade; a sunny to light‑shaded spot under fruit trees also works. Allow the root ball some space, 50 to 60 cm between plants, to prevent later transplanting. Keep the soil consistently moist, especially in the first year, but avoid waterlogging. After flowering in early summer (around the end of June), cut back the plant before seed maturity to keep it compact and encourage new leaf growth. As a hardy perennial, it requires no special winter protection and reliably regrows each year.
