Where/how to plant: we recommend that you plant this species in its native habitat, or conditions that mimic its native habitat, such as in recently disturbed, sandier soils Management: to fulfill the plant's need for disturbed soil habitat, regularly create clearings and maintain them by thinning trees and vegetation and by delaying secondary ecological succession; plots may need to be reestablished every 3-4 years because this plant tends to be out-competed quickly; cut 2-6 inches from the plant to encourage vigorous growth
Notes: will not grow in conditions that are hot and dry; requires consistently moist soil
