Ornamental Grasses: Movement in the Garden
Various genera
Ornamental grasses add sound, movement, and four-season structure. Seed heads catch morning light. Winter silhouettes add interest when everything else has died back. Almost maintenance-free once established.

Care & growing tips
Plant in full sun with average soil. Cut back to 4–6 inches in late winter before new growth emerges. Divide every 3–5 years for tall species. Avoid over-fertilizing — too much nitrogen causes flopping.

Frequently Asked Questions
01 When do I cut back ornamental grasses?
Late winter — just before new growth. Leave them standing all winter for visual interest and wildlife cover.
02 Are ornamental grasses invasive?
Some are. Miscanthus sinensis and pampas grass reseed aggressively in some regions. Check with your local extension office before planting. Clump-formers like Calamagrostis 'Karl Foerster' stay where you put them.
03 Do ornamental grasses need a lot of water?
Most are drought-tolerant once established. During the first year, water deeply once a week. After that, they thrive on rainfall alone in most climates. Overwatering causes flopping.
