Synonym(s): wild parship
Wild parsnip is a biennial/perennial herb that can grow up to 4 ft. (1.2 m) in height. Leaves are alternate, compound and branched with jagged teeth. Flowering occurs from May to June, when hundreds of yellow flowers develop. Flowers are arranged in an umbel. Fruits are dry, smooth, slightly winged and flattened on back. Fruits each contain two seeds, which are dispersed in the fall. Wild parsnip is native to Eurasia and occurs in sunny areas with varying degrees of soil moisture. Contact with this plant can cause skin to become photosensitive; exposure to sunlight can cause severe blistering.
