White Camas (Anticlea elegans ssp. glaucus)

Life history

Species overview

White Camas (Anticlea elegans ssp. glaucus), a Wisconsin Special Concern plant, is found in a variety of habitats, including oak openings, wet-mesic calcareous prairies, limestone-capped sandstone bluffs, cliffs, outcrops, and stabilized dunes along Lake Michigan. Blooming occurs late May through late July; fruiting occurs mid August through early September. The optimal identification period for this species is late May through late July.

Synonyms: Anticlea chlorantha, Melanthium glaucum, Zigadenus elegans var. glaucus, Zigadenus glaucus

Identification

  • Distinguishing characteristics: Leaves linear, crowded toward the base of the plant, with tall panicle of 6 parted greenish-white flowers.
  • Flower characteristics: Inflorescence paniculate, bearing flowers with 6 white petal-like tepals, usually purple beneath and with green or yellow spots near center.
  • Fruit characteristics: Ovoid capsule 10 to 15 mm long, barely exceeding the persistent perianth.
  • Leaf characteristics: Crowded toward the base, narrow to broadly linear, 2 to 4 dm long and up to 12 mm wide, attenuate.

Phenology

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 a variety of habitats, including oak openings, wet-mesic calcareous prairies, limestone-capped sandstone bluffs, cliffs, outcrops, and stabilized dunes along Lake Michigan.
  • Soils: Moist, calcareous soils.

Natural communities

This table lists the natural communities that are associated with White Camas. 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 White Camas. 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.

  • No avoidance measures have been developed for this species.

Management guidance

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

  • Maintain low to partial canopy; avoid closed canopy conditions.
