'Shenandoah' is a compact cultivar of switchgrass, a warm-season bunchgrass native to tallgrass prairies and open ground across most of the contiguous United States. It is prized among switchgrass cultivars for coloring earlier and more intensely than the species — blue-green blades develop wine-red tips by midsummer and deepen to full burgundy-red by fall, well ahead of straight-species Panicum virgatum.
Airy, pink-tinged seedhead panicles rise above the foliage in late summer and persist into winter, providing movement and structure along with forage for birds. It is more tolerant of periodic wet soil and light shade than most prairie grasses, though it colors best and stays most upright in full sun; overly rich soil or too much shade causes floppy growth and muted fall color. Its dense root system makes it useful for erosion control on slopes and rain garden margins.
'Shenandoah' has no meaningful culinary or medicinal history, but functions as a compact, well-behaved substitute for larger switchgrass cultivars in smaller borders, offering strong wildlife and pollinator-adjacent structural value through the seedheads and standing winter foliage.
Rust
Orange to brown raised pustules on the undersides of leaves, with yellow spotting on the upper surface. Heavy infections cause leaves to yellow and drop.
Remove and destroy infected leaves. Avoid overhead watering and improve air circulation. Apply a sulfur or copper-based fungicide if it spreads. Clear plant debris in fall.
Crown Rot
Lower leaves yellow and wilt; the base of the rosette turns brown and soft, sometimes with white fungal threads at the soil line. Plants collapse in wet conditions.
Remove and destroy affected plants. Improve drainage and avoid overhead watering. Do not mulch directly against the crown. Space plants for airflow and avoid replanting in the same wet spot.
