Range and Habitat in Illinois

Pale Penstemon is occasional throughout Illinois, except in east-central and some northern areas of the state, where it is uncommon or absent (see Distribution Map). Habitats include dry rocky woodlands, hill prairies, dry-mesic railroad prairies, sandstone and limestone glades, upland savannas, thinly wooded bluffs, rocky cliffs, and abandoned fields. Occasional wildfires are beneficial in maintaining populations of this species, particularly in wooded habitats.
