Rotstrahlbusch Switch Grass

Rotstrahlbusch is an upright, clump-forming switch grass known for foliage that shifts from green to red and deep burgundy, with pink-tinged flower panicles in summer. The Royal Horticultural Society lists a mature height of 1–1.5 m and spread of 0.5–1 m. [RHS plant profile](https://www.rhs.org.uk/plants/47192/panicum-virgatum-rotstrahlbusch/details) ## Seasonal display The foliage develops red tones through summer and turns deep burgundy in autumn; tan stems and seed heads can remain decorative in winter. Pink-tinged panicles rise above the leaves in midsummer. Its upright form suits mixed borders and prairie-style plantings. ## Growing conditions Plant in full sun in moderately fertile, well-drained soil. Allow room for a spreading clump and water while it establishes. The RHS H5 rating is a UK hardiness measure and is not presented as a USDA zone. ## Maintenance Leave stems through winter if their structure is desired, then cut the previous season’s growth back in late winter or early spring before new shoots emerge. Remove damaged or unwanted stems at the base. [Morton Arboretum](https://mortonarb.org/plant-and-protect/trees-and-plants/switch-grass/) also describes its pink-burgundy seed heads and fall foliage.
