Native Range

Moist meadows and open woodland; Connecticut to Michigan and Nebraska south to Texas and Florida.


In new housing developments, trees and shrubs used by birds for nesting, perching and escaping predators may be in short supply. Evergreens offer valuable year-round cover from the weather and predators in addition to secluded nesting sites.




This plant is easy to grow in average, moist, well-drained soils in full sun. Will grow in light shade, but may need support if grown in too much shade. Tolerates heat, some drought and wide range of soils. Remove spent flowers to encourage additional bloom and/or to prevent any unwanted self-seeding. Leave old flowers on the plant if you want to feed the birds. These plants freely self-seed and will usually remain in the garden and naturalize.
