Product Description
Panicum virgatum ‘Shenandoah’ (Shenandoah Switchgrass) is a compact, refined selection of native Switchgrass prized for its early and reliable red to burgundy foliage color. Blue-green blades flush wine-red by midsummer, deepening to rich burgundy with the onset of fall. Fine, airy panicles float above the clumps in late summer, and stems stand into winter for four-season structure and wildlife value. Exceptionally adaptable—from dry to periodically wet soils—‘Shenandoah’ delivers movement, color, and durability for borders, meadows, streetscapes, and low-maintenance designs.

Care & Growing Information
- Site & Light: Plant in full sun for the richest red color, most upright habit, and best bloom.

- Fertility: Keep nutrients moderate to lean—excess fertility or irrigation can cause flopping and mute foliage color.
- Planting: Set crowns level with soil; space 18–30″ for airflow and vertical poise. Water to establish, then reduce.
