Carolina Anemone (Anemone caroliniana)

Life history

Species overview

Carolina Anemone (Anemone caroliniana), a Wisconsin Endangered plant, is found in dry bluff and sand prairies and gravelly hillsides, mostly near the Mississippi and lower Chippewa Rivers. Blooming occurs early April through late May; fruiting occurs late May through late June. The optimal identification period for this species is throughout May.

Synonyms: None

Identification

  • Distinguishing characteristics: The combination of the highly dissected leaves and the numerous (greater than 10) sepals distinguish this species.
  • Flower characteristics: Flowers medium to large in size (2.5 to 4 cm wide); petals absent; sepals petal-like, 10 to 20, white to purple-colored.
  • Fruit characteristics: Fruiting head is narrowly elipse-like in shape and 13 to 20 mm in size; seed woolly.
  • Leaf characteristics: Deeply palmately divided basal leaves and a whorl of 3 stalkless cauline (stem) leaves at or below the middle of the flowering stem.

Phenology

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

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 dry bluff and sand prairies and gravelly hillsides, mostly near the Mississippi and lower Chippewa Rivers.
  • Soils: Dry, sandy or gravelly soils.

Natural communities

This table lists the natural communities that are associated with Carolina Anemone. 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).

Ecological landscapes

This table lists the ecological landscape association scores for Carolina Anemone. The scores (3=High, 2=Moderate, 1=Low, 0=None) also correspond to the map.

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 locating landings, staging areas, or access routes in open sandy areas dominated by native grasses.
  • 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 guidance

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

  • Maintain and restore open habitat through selective clearing and brushing.
  • Prescribed burns and/or brushing may be beneficial (dependent on local site conditions).
