NOTE: Although wild parsnip has edible roots, it should be avoided because of the possibility of confusion with poison hemlock. Plant the seeds an inch apart and half an inch deep. Parsnip seeds are only good for one year, so buy new seeds each year. Caution: Do not touch this plant What is wild parsnip Wild parsnip is an invasive plant from Europe and Asia that has. ![]() Wild parsnip produces huge amounts of seed, allowing it to persist and spread. Even then, they take two to three weeks to come up out of the ground. The leaves of poison hemlock are usually more finely divided and its stems are hollow and purplish. It grows best in rich, calcareous, alkaline, moist soils. It can survive in a broad range of environmental settings, from dry soils to wet meadows. Similar plants: Second-year plant is somewhat similar to poison hemlock ( Conium maculatum). Wild parsnip is an herbaceous plant which can grow from 4 5 feet (123 150 cm) tall. ![]() How To Get Rid of Wild Parsnips To treat growing Wild Parsnips, we recommend applying 2,4-D Amine Selective Weed Killer. Many small flowers with five yellow or white petals borne in umbrella shaped terminals – gives rise to yellow seed clusters, 2-6 inches across. Wild Parsnips are a common weed that grows on properties, roadsides, along train tracks and is known for its sap that can causes painful rashes and blisters. Up to 18 inches long.įlower: May-August (second year). Leaves: Alternate, pinnately compound with coarse saw-tooth edges deeply lobed and not hairy. Second Year Growth Habit: 2-5 feet, branched, flowering plant. Wild Parsnips are a common weed that grows on properties, roadsides, along train tracks and is known for its sap that can causes painful rashes and blisters. Large, three-lobed leaves resemble celery. Life cycle: Biennial, forming a rosette the first year and producing flowers and seed in the second.įirst Year Growth Habit: Rosette of basal leaves. Of course, giant hogweed has a more threatening sounding common name while wild parsnip sounds like a vegetable gone wild which it actually is Parsnips have been cultivated as a root crop in Europe for centuries, perhaps millennia. Staff or volunteers doing this work must avoid all skin contact with the plant so protective clothing is a must.Habitat: Wastelands, wet sites, roadsides and pastures, undisturbed ground. Wild parsnip is found throughout the state and is equally damaging. Areas of heavy infestation are mowed with follow up herbicide or hand cutting or pulling of stray plants. In dense populations herbicide application is used. Plants can be pulled if the ground is wet, or the tap root of each plant can be cut with a sharp-bladed shovel. Cowling Arboretum Procedures for Removal:Ĭontrol of wild parsnip can be done by hand if the infestation is small. It is hoped that with consistent control with herbicides, mowing and digging, the populations can be eliminated or at least controlled. To this point, the spread of wild parsnip has been mostly confined to the roadside ditch on Highway 19, Hillside Prairie and the southern portions of the newly planted ’06 and ’04 prairie fields. Wild parsnip has only begun showing up in large numbers in the Arboretum in the past few years, and these plants have been the subject of mowing and spraying. Because of wild parsnip’s success in prairies and oak savannas it is a target species for eradication in the Cowling Arboretum. It is shade-intolerant, however, preferring sunny conditions, and as conditions for wild parsnip growth become more optimal seed production increases greatly. It is tolerant of a wide range of conditions, including dry, mesic, and wet-mesic prairies oak openings and calcareous fens, and is primarily a problem in southern Minnesota in prairies and oak openings. The rash is similar to a severe burn and may take many weeks to heal, leaving long lasting scars.Ī native of Europe and Asia, wild parsnip has escaped from cultivation in the United States. Contact with the sap of wild parsnip combined with the presence of sunlight causes phytophotodermatitis, very unpleasant rashes on skin, making this plant difficult to remove by hand.Wild parsnip grows very rapidly and is persistent, even after being sprayed.Wild parsnip invades slowly, but once populations build it spreads rapidly and can severely modify open dry, moist, and wet-moist habitats, soon dominating areas.Wild parsnip readily moves into disturbed habitats, along edges and or in disturbed patches. ![]() Wild parsnip infestation Reasons Wild Parsnip is a problem: ![]()
