This umbelliferous biennial or perennial grows upwards of 4 ft. high, and has large deeply-divided leaves and umbels of yellow flowers in roundish heads. It flourishes in rich, moist soil, and is raised from seeds sown in spring or when ripe in August. The seedlings are transplanted about 2 ft. apart each way, and the leaves are eaten raw or cooked for use with fish or flesh. The seeds are used for flavouring, and the spindle-shaped roots are employed medicinally.
