A fine-textured ornamental grass with feathery, bottlebrush-like plumes that emerge in late summer and persist into fall. Drought-tolerant once established, it adds movement and interest to sunny garden spaces.

Why grow it

Chinese Fountain Grass offers finer texture and more delicate plumes than many clumping ornamental grasses, making it useful where a softer visual effect is desired in dry or difficult soils. It reaches moderate height (3-4 feet) and width, fitting intermediate spaces where larger miscanthus or smaller sedges might be less suitable. Once established, it requires minimal supplemental water in most climates, reducing maintenance compared to more moisture-dependent ornamental species.

Watch out for

This grass can take a season or two to reach full size and flowering capability, so patience is needed during establishment. In areas with hot, humid summers, ensure good air circulation around the plant to reduce fungal issues. Cutting back spent plumes in late winter or early spring requires care to avoid damaging emerging new growth.
