Product Description
Panicum virgatum ‘Northwinds’ (Northwinds Switchgrass) is a celebrated selection of native Switchgrass known for its narrow, columnar habit and clean, blue-green foliage that holds rigidly upright through the season. Airy, fine panicles float above the foliage in late summer, then shift with the leaves to warm gold/tan tones for standout fall and winter structure. Exceptionally adaptable—from dry to periodically wet soils—‘Northwinds’ is ideal for meadows, tight screens, streetscapes, and low-maintenance borders where vertical poise, movement, and durability are essential.

- Fertility: Keep nutrients moderate to lean—excess fertility or irrigation can cause flopping.
- Planting: Set crowns level with soil; space 24–36″ for airflow and vertical poise. Water to establish, then reduce.
