Fire Pink (Silene virginica)

Life history

Species overview

Fire Pink (Silene virginica), a Wisconsin Endangered plant, is found in dry to mesic, oak woodlands, preferring partial shade. Blooming occurs late May through early July; fruiting occurs late June through late July. The optimal identification period for this species is late May through early July.

Synonyms: Silene virginica var. virginica

Identification

  • Distinguishing characteristics: The bright red petals, which are notched at the tips distinguish this species.
  • Flower characteristics: Inflorescence open, 7 to 10 flowered; calyx broadly tubular, 18 to 22 mm; petals crimson with 3 mm tubular appendages; limb linear-oblong, 15 to 22 mm, 2-lobed; styles 3.
  • Fruit characteristics: Capsule dehiscent by 6 teeth; seeds roughened.
  • Leaf characteristics: Opposite, entire; basal leaves oblanceolate or spatulate, petiolate, 4 to 10 cm long by 8 to 18 mm wide; cauline leaves in 2 to 4 pairs, sessile or nearly so, to 30 cm long and 3 cm wide.

Phenology

  • Blooming phenology: late May through early July
  • Fruiting phenology: late June through late July
  • Optimum time to identify: late May through early July

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 to mesic, oak woodlands, preferring partial shade.
  • Soils: Rich, rocky soils.

Natural communities

This table lists the natural communities that are associated with Fire Pink. 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 Fire Pink. 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.

Fire Pink (Silene virginica) has very few known occurrences in the state and is of the highest priority for conservation; we encourage you to consult with your District Ecologist or NHI Botanist for specific recommendations for your site.

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 partial canopy to encourage woodland species; avoid closed-canopy conditions.
  • Prescribed burns and/or brushing may be beneficial (dependent on local site conditions).
  • Survey for and control invasive plants prior to conducting timber operations, as these can be spread by vehicles and often respond vigorously to increased light; see forestry BMPs for invasive species.
