About

Anethum graveolens 'Mammoth' is a strong-growing annual or biennial characterized by its finely cut, fragrant blue-green foliage. In the summer, it produces large, flat clusters of small yellow blooms. This robust variety is favored for its size and vigor. Many gardeners cultivate it annually to harvest fresh leaves, which are commonly used in culinary applications, especially with fish eggs and potatoes. Additionally, it serves well as a cut flower and provides aromatic foliage for arrangements. Dill typically flowers and sets seed in its second year. All parts of the plant, including the leaves, flowers, and seeds, are edible. The seeds, in particular, are valued in cooking, offering a milder taste that enhances pickles, vinaigrettes, and marinades.
