Sium latifolium
Also called Greater water-parsnip, Great Water Parsnip
Sium latifolium is a hardy perennial water plant of the carrot family, native to much of Europe and Siberia, that grows in swamps, lakeshores and shallow water. Keep its roots consistently wet and give it full sun to part shade.
Sium latifolium is a species of flowering plant in the family Apiaceae known by the common names great water-parsnip, greater water-parsnip, and wideleaf waterparsnip. It is native to much of Europe, Kazakhstan, and Siberia.
This plant grows in wet habitat such as swamps and lakeshores, sometimes in the water. It is a perennial herb with a hollow, grooved stem up to 2 meters tall. The herbage is green and hairless. The leaves are up to 30 centimeters long with blades borne on hollow petioles that clasp the stem at their bases. The inflorescence is an umbel of white flowers.
The rootstock is acrid and poisonous, but the leaves have been cooked and eaten as a vegetable in Italy and the ripe seeds - which are aromatic due to their limonene content - have been used (in small quantities) as a spice or seasoning in Scandinavian cuisine.
