Anethum graveolens 'Mammoth'
dill 'Mammoth'
A vigorous upright annual or biennial with finely dissected, aromatic blue-green leaves, and large flat umbels of tiny yellow flowers in summer. This is a popular and slightly larger robust variety. Grown popularly each year as an annual for fresh leaves and used as a herb in cooking - particulalry fish eggs and potatoes, and also grown as a cut flower and for cut scented foliage. Dill will often flower and go to seed in its second year. The leaves, the flowers and the aromatic seeds are all edible. Dill seeds are important culinary additions, and their flavour can provide a more subdued flavour. Dill seed is used in pickling, and features in vinaigrettes and marinades.
