- Description
-
The Hairy-Joint Meadow-Parsnip is a perennial wildflower in the Apiaceae (Carrot) family native to central and eastern USA and in most areas of NC, except the eastern counties. It is named from stiff hairs at the stem branches on most plants although they are not easy to see unless you know exactly where to look. It is found in moist forested areas, and along streams and ponds and occasionally prairies in full sun to partial shade although shade will impact its growth and number of blooms. Bloom time is in spring to early summer with light yellow flowers occurring in clusters that attract many pollinators.
The compound leaves have parsley-like leaflets. It grows up to 6 feet tall and starts to decline after blooming. Large compound leaves are alternate and tend to be near the base of the plant. Leaflets have medium to large coarsely toothed edges and are 1-2 inches long and .5 - 1 inch across. A few smaller leaves occur up the stem, gradually reducing in size. Surfaces are minutely hairy, especially along the veins and around the edges.
The flowers are in flat-topped umbels (clusters) 2 to 3 inches wide, in 8 to 20 groups of up to 20 flowers each. Individual flowers are all stalked, about 1/8 inch across with 5 yellow petals that fold inward and 5 yellow stamens.
The fruit displays from July to August. Oblong seeds are 1/4 in. long and ripen to dark brown. Seeds typically are not widely dispersed. When the dead stems drop, it can be seen that most of the fruits remain attached to the plant.
The Hairy-Joint Meadow-Parsnip will tolerate dry to moist conditions but prefers moist soil. It can be grown in sand, loam and slightly rocky soil of any pH. It is used in naturalized areas, pollinator gardens, along streams and ponds and native gardens.
