Description

Black fountain grass is an ornamental plant with a spreading, clumping habit from the grass family (Poaceae). Moudry is a vigorous grower, often extending out to 3 feet wide, known for its long lasting maroon colored flowers. Wide, dark green, glossy leaves are more upright in form than other fountain grasses. A prolific self seeder in warm climates, it was introduced by the U.S. National Arboretum.

It grows best in full sun but will tolerate part shade. Growing in the shade may lead to less flowering. Highly tolerant of moist to wet soils; it lends itself well to plantings in rain gardens, ponds and slopes for erosion control. In warm climates it may become an aggressive spreader and should be cut back before seeds mature. Division is the best form of propagation.

Moudry received the Royal Horticultural Society Award of Garden Merit in March 2021 for its ornamental qualities and vibrant color.

This plant attracts pollinators and songbirds. As a specimen plant it performs well in mass plantings or combined with contrasting perennials in mixed perennial borders.  Its height and color make it an excellent filler in large containers and pots. See native alternatives to the left.

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