Description

Oriental fountain grass is an ornamental plant with a spreading, clumping habit from the grass family (Poaceae). Mid-sized among the fountain grasses, growing to about 2 feet tall, it has green to gray-green leaves with pinkish white flowers that darken to mauve in the fall.

Oriental fountain grass grows in moist, well-drained soil and is drought-tolerant once mature. Does well in acid, alkaline and neutral soil as long as drainage is good. This is a warm-season grass as it does not tolerate frost well and should be planted in a sheltered position in the garden. Propagation is best by division.

This species is listed as a recommended ornamental with the Royal Horticultural Society and received the Award of Garden of Merit in July 2017. However, it has the potential to be weedy. See native alternatives to the left.

This versatile plant performs well in mass plantings or combined with contrasting perennials in mixed perennial borders. It is often used along walkways and slopes. Once mature and drought tolerant can be used in a xeriscape landscape.

Insects, Diseases and Other Plant Problems:  No notable issues. Weedy. Is deer and rabbit resistant.
