Light. Fountain grass does best in full sun and grows poorly in shade.
Water. Water regularly while it settles in. After that it is moderately drought tolerant. It needs a well-drained site.
Soil and feeding. It grows in sand, loam or clay, from acidic to slightly alkaline, as long as the soil drains well.
Size. Grows to about 4 ft in a clump 2–4 ft wide.
Problems to watch. No pests or diseases are of major concern. Its seeds sprout small plants nearby; pull them while small.
Good to know. Use it as an accent, in mass plantings or borders, or in containers. The plumes can be cut for arrangements, though they fall apart when dried.
