WILDLIFE & INSECTS
Birds
- Provides seeds for songbirds and valuable cover for birds as its upright stems remain standing through fall and winter.
Butterflies
- Serves as a larval host for several skipper and butterfly species including the Common Wood Nymph and Leonard's Skipper while also providing valuable habitat within native plantings.
Spacing & Landscape Use
Spacing Recommendations
- Space 18 - 24 in apart to create a strong mass while allowing its narrow upright form to remain distinct.
Landscape Placement
- Ideal for native gardens, prairie plantings, sunny borders, and erosion prone areas where its upright form and dramatic fall color create strong seasonal structure.
Companion Plants
