Switch Grass 'Prairie Sky' (Panicum virgatum): A Blue-Foliaged Cultivar with Upright Habit

Switch Grass 'Prairie Sky' is a cultivar of Panicum virgatum selected for its intense blue foliage and strongly upright, narrow form. It is a native prairie grass adaptation for formal and naturalistic gardens.

Vertical Blue Accent

This grass forms a tight, columnar clump 4–5 feet tall but only 2–3 feet wide. The leaves are a striking metallic-blue. In late summer, airy, pinkish panicles appear just above the foliage, aging to tan. Fall color is golden-yellow. The narrow habit makes it useful in tight spaces and as a vertical accent.

Culture

Full sun, well-drained soil. Drought-tolerant, adaptable to clay and sand. Hardy to zone 4. Cut back in late winter. 'Prairie Sky' offers the blue color of 'Dallas Blues' in a more compact, upright package.
