Pale Purple Coneflower (Echinacea pallida)
Pale Purple Coneflower (Echinacea pallida), a Wisconsin Threatened plant, is found in prairies and prairie remnants along roadsides and railroads. Blooming occurs early June through late July; fruiting occurs early July through late August. The optimal identification period for this species is early June through early August.
Synonyms: Brauneria pallida, Echinacea pallida var. pallida, Rudbeckia pallida
- Distinguishing characteristics: Distinguished from E. angustifolia by overall size, larger ray flowers and white (not yellow) pollen.
- Flower characteristics: Single showy flower head at the top of each stem, with many drooping, pale purple, petal-like ray flowers, each up to 3.5 in long; disk purplish-brown, broad, cone-shaped.
- Fruit characteristics: Cypselae tan or bicolored, 2.5 to 5 mm, faces more or less smooth, usually glabrous.
- Leaf characteristics: Rough-surfaced, up to 10 in long and 1.5 in wide, tapering at either end, with several paralel veins running along their lengths; basal leaves on long stalks; stem leaves few and usually lack long stalks.
- Blooming phenology: early June through late July
- Fruiting phenology: early July through late August
- Optimum time to identify: early June through early August
- Growth form: Forb-erect
- Vegetative reproduction:
- Life cycle: Perennial

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 prairies and prairie remnants along roadsides and railroads.
- Soils: Dry, mesic soils.
This table lists the natural communities that are associated with Pale Purple Coneflower. 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).
This table lists the ecological landscape association scores for Pale Purple Coneflower. The scores (3=High, 2=Moderate, 1=Low, 0=None) also correspond to the map.
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.
These are specific actions designed to avoid "take" (mortality) of this species.
- Avoid broadcast spraying of herbicides; use care with spot spraying.
- 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.
Management guidelines are additional considerations that may help maintain or enhance habitat for this species
- Prescribed burns and/or brushing may be beneficial (dependent on local site conditions).
- Maintain and restore open habitat through selective clearing and brushing.
