Characteristics of Prairie Plants

Key for table

Competitiveness: 1= aggressive, can compete with weedy and exotic species, easiest to establish; 2 = intermediate, not as competitive with weedy and exotic plants, slower to establish; 3 = competition sensitive, will not compete and declines or dies with weedy species and exotics.

Old fields, disturbed sites: Native prairie plants that can be found growing on extensively disturbed sites. These species can be tough enough to survive grazing, mowing, plowing, spraying, or some other land management practices.

Plants restricted to virgin prairies: Prairie plants found growing on virgin (not plowed or disturbed) prairie remnants. Most of these plants will not tolerate any kind of disturbance such as plowing, heavy grazing, or mowing.

Plants established by seeds or plants: Some prairie plants can be established by seeds (S) or (P) or both (S/P). Recommendations are based on the difficulty of germination, survival rate, growth rate, and what is currently available through nurseries. Native plants should be nursery-propagated and purchased through licensed nurseries to support the conservation of native species.
