Hairy Meadow Parsnip (Thaspium chapmanii)

Life history

Species overview

Hairy Meadow Parsnip (Thaspium chapmanii), a Wisconsin Endangered plant, is found in open woods and woodland edges, often with dolomite near the surface. Blooming occurs early May through late June; fruiting occurs early June through late October. The optimal identification period for this species is early June through late September.

Synonyms: Ligusticum barbinode, Thaspium barbinode, T. barbinode var. chapmanii, T. barbinode var. angustifolium


  • Distinguishing characteristics: Distinguished by its leaves which are 2 or 3 times compound and its rounded inflorescence of pale yellow flowers. Look, also, for minute hairs near the stem nodes.
  • Flower characteristics: Pale yellow or cream-colored; bractlets linear, acute, 1 to 4 mm.
  • Fruit characteristics: Smooth, ellipsoid, 4 to 6 mm; lateral and some of the dorsal and intermediate ribs broadly winged.
  • Leaf characteristics: Basal and principal cauline leaves twice pinnate or ternate-pinnate; leaflets ovate to lanceolate, serrate to incised.


  • Blooming phenology: early May through late June
  • Fruiting phenology: early June through late October
  • Optimum time to identify: The optimal identification period for this species is early June through late September


  • Growth form: Forb-erect
  • Vegetative reproduction:
  • Life cycle: Perennial
  • Comments: Associated Species: Quercus macrocarpa, Q. alba, Schizachyrium scoparium, Bouteloua curtipendula, Hystrix patula, Elymus villosus.

Habitats and landscapes

The Natural Heritage Inventory has developed scores indicating the degree to which each of Wisconsin's rare plant species is associated with a particular natural community or ecological landscape. This information is similar to that found in the Wildlife Action Plan for animals. As this is a work in progress, we welcome your suggestions and feedback.

General habitat information

  • Habitat description: Found in open woods and woodland edges, often with dolomite near the surface.
  • Soils: Moist soils with loam, sand or rock.

Natural communities

This table lists the natural communities that are associated with Hairy Meadow Parsnip. Scores for natural community associations are: "significant" association (score=3), "moderate association" (score=2) or the species can be present but is only weakly associated with the community (score=1).

Species guidance

The Endangered Resources Program has developed avoidance measures and management guidelines for plants on the Natural Heritage Working List. These are a work in progress, and we welcome your suggestions and feedback. Sources used in developing this information can be found here.

Avoidance measures

These are specific actions designed to avoid "take" (mortality) of this species.

  • Avoid known individual plant locations and conduct operations elsewhere when they are least likely to cause damage. Ideally, this would involve frozen, snow-covered ground. However, in areas of the state where frozen conditions are unreliable, very dry soils late in the growing season might be the best available alternative. Consult with a biologist, if needed.
  • Avoid broadcast spraying of herbicides; use care with spot spraying.

Management guidance

Management guidelines are additional considerations that may help maintain or enhance habitat for this species

  • Maintain open to partially open canopy; avoid closed canopy conditions.
  • Prescribed burns and/or brushing may be beneficial (dependent on local site conditions).
