Glyceria striata (Fowl Mannagrass)

Glyceria striata (Fowl Mannagrass) is a long-lived, perennial bunchgrass forming a robust clump of soft, ribbon-like leaves, 6-10 in. long (15-25 cm). In early to mid-summer, each erect to ascending culm terminates in an airy pyramid-like panicle of spikelets, up to 12 in. long (30 cm), with spreading and drooping branches. The seed is food for waterfowl and birds while the foliage and tall stems provide good wildlife cover. The foliage is seasonally grazed by deer, muskrats, and bears. Occurring across most of North America, Fowl Mannagrass is found in bogs, seeps, wet woods, thickets or swampy areas, shaded ditches, and along or in streams. It may occasionally be found growing in full sun on summer damp soils as well as in standing water. The root system is fibrous. Fowl Mannagrass spreads by reseeding itself and occasionally forms colonies. Useful for restoration of swamps, the edges of marshes, ponds, and streams, it is an excellent choice for a water garden, wetland garden, or near ponds and streams.

• Grows up to 24-48 in. tall (60-120 cm).
• Performs best in full sun to part shade in moist to wet soils. Fowl mannagrass tolerates open areas but prefers shady habitats. Prefers soil containing loam or clay. Grows poorly in sandy soils. This species does not tolerate salinity and needs moderately good fertility.
• A good choice for plantings in bog gardens, rain gardens, or near ponds and streams.
• No serious pest or disease issues. Keep an eye out for fungal pathogens such as Epichloe glyceriae, which causes floral castration, and Ustilago striiformis, better known as stripe smut.
• Propagate by seed.
• Native to much of North America, from Alaska and northern Canada to northern Mexico.
