Bluestem Pawnee
Andropogon gerardii 'Pawnee'
grassBluestem Pawnee is a cultivar of Big Bluestem, a native warm-season prairie grass prized for its striking three-pronged seed heads resembling a turkey foot and dramatic fall color that transitions from green to deep burgundy and purple. This ornamental grass is extremely hardy, drought-tolerant, and provides excellent wildlife habitat and soil stabilization. It grows 3-5 feet tall and is a key component of prairie restoration and sustainable landscaping.

Germination & Seedling
8-12 weeksSeeds germinate in spring (60-90 days after fall planting or after cold stratification). Fine, thread-like shoots emerge and develop into thin grass blades.
Keep soil consistently moist but not waterlogged during first 8-12 weeks. Thin seedlings to proper spacing if direct seeded. Mulch lightly to retain moisture.
Establishment & Root Development
12-16 weeks (spring through fall)First-year plants focus on root development; above-ground growth remains modest (12-24 inches). Deep fibrous root system establishes during first season.
Water weekly during drought. Apply 1-2 inches of mulch to conserve moisture and suppress weeds. Avoid fertilizing; native soil conditions are preferred.
Vegetative Growth
Spring to midsummer (4-5 months)In year 2 and beyond, vigorous upright growth occurs spring through mid-summer. Dense clumps of fine, blue-green foliage develop; culms (stems) elongate.
Once established, little supplemental water needed. Avoid feeding; this promotes weak, floppy growth and reduces stress hardiness. Remove winter mulch in early spring.
Flowering & Seed Head Development
August to NovemberMid to late summer through fall, distinctive three-pronged seed heads emerge (resembling a turkey foot). Foliage gradually transitions from green to deep burgundy, purple, and bronze.
No deadheading—allow seed heads to develop for structure and wildlife food. Autumn color intensifies with cool nights and frost. Seed heads persist through winter.
Dormancy & Winter Structure
November to MarchLate fall through winter, foliage turns rich burgundy to nearly black; leaves and seed heads dry completely but remain upright and ornamental.
Do not cut back until early spring (late March to April) to provide winter interest and wildlife shelter. Cut back to 3-4 inches above ground with mower or pruners.

Common Pests
-
Rarely problematic; maintain healthy plants. Hand-pick if needed; predatory insects usually control populations naturally.
-
Uncommon in prairie grasses. Ensure proper drainage and avoid over-irrigation, which stresses plants.
-
Rare on Big Bluestem. Rotate plantings and avoid amending soil excessively, which attracts pests.
Uses
Pollinator & Wildlife Habitat
WildlifeProvides seeds for birds in fall and winter; dense growth offers shelter for beneficial insects and small mammals. Essential native plant for prairie restoration and supporting biodiversity. [source]
Ornamental & Landscape Design
HouseholdStriking year-round interest: blue-green spring foliage, distinctive turkey-foot seed heads in late summer, and deep burgundy-to-black fall and winter color. Ideal for rain gardens, erosion control, and modern prairie landscapes. [source]
Erosion Control & Soil Stabilization
HouseholdDeep fibrous root system (up to 12 feet) prevents soil erosion on slopes and in riparian zones. Improves soil structure and water infiltration. [source]
Dried Flower Arrangements & Crafts
CraftSeed heads and dried stems are prized for fall and winter flower arrangements, wreaths, and craft projects. Collect in late autumn for long-lasting display. [source]
Carbon Sequestration & Climate Resilience
HouseholdDeep root systems sequester carbon in soil; extremely drought and heat tolerant, making it ideal for sustainable landscaping in a changing climate. [source]
Harvest Tips
Bluestem Pawnee is not harvested for food but rather enjoyed for ornamental and ecological value. Seed heads can be collected in late fall (October-November) for dried arrangements or seed propagation by cutting stems just above the base. Leave plants standing through winter, then cut back to 3-4 inches in early spring before new growth begins. Divide mature clumps in spring every 3-4 years if desired.
Fun Facts
- 🌱 The common name 'turkey foot' comes from the distinctive three-pronged seed head (technically a tripartite inflorescence) that resembles a turkey's foot print.
- 🌱 Big Bluestem roots can extend 12 feet deep, among the deepest of any North American plant, allowing it to access water during severe droughts.
- 🌱 The blue-purple color in foliage and stems comes from anthocyanin pigments that intensify in cool fall weather, creating the spectacular burgundy-to-black autumn display.
