Grass - Carex pennsylvanica 'Straw Hat' PP29432

Provides cover and nesting material for small animals and insects

Supports native ecosystems as a host plant for some caterpillars and beneficial insects

Spring: fresh green foliage emerges; subtle straw-colored flower spikes appear

Summer: maintains lush, arching green carpet-like foliage

Fall: foliage may yellow slightly but remains attractive

Winter: semi-evergreen in mild regions; in colder zones, foliage declines and returns in spring

– Shade groundcover, turf alternative under trees, naturalizing in woodland gardens, erosion control on shaded slopes, pairing with ferns and Hostas

Fine-textured, arching, semi-evergreen blades of soft green

Forms low, graceful mounds that spread into carpets

Leaves remain fresh-looking into summer if kept moist

Produces straw-colored, inconspicuous seed heads in late spring to early summer

Seed heads are not showy but give the plant its cultivar name "Straw Hat"

Plant in well-drained, moderately fertile soil enriched with organic matter for best results

Space 12–18 inches apart; spreads by rhizomes to form dense, low carpets

Plant crown level with the soil surface; water well after planting

Works well in mass plantings, shaded slopes, or as a turf alternative

Best planted in spring or early fall to establish before summer heat or winter cold

Trim back old foliage in late winter or early spring before new growth emerges

Can be lightly sheared in midsummer to refresh appearance if foliage becomes untidy

Prefers evenly moist soil, especially in establishment phase

Once established, tolerates periods of dryness but performs best with regular moisture

Avoid prolonged drought for optimal appearance

Thrives in partial to full shade, making it excellent for under trees and woodland gardens

Can tolerate filtered morning sun in cooler climates but avoid hot, direct afternoon sun
