Common Name Gamagrass
Family Poaceae
Info "Family Name: Poaceae Summary: Gama Grass is a type of perennial grass. Nativity/Habitat: Native to the Eastern United States. Gamagrass can be grown in tall grass prairies, limestone glades, abandoned fields, thickets, wood margins, salt marshes, stream banks, and roadsides. Morphology/Physiology: -Foliage: Found in clumps of arching leaves. Leaves grow to a height of 4-8 ft. and spread from 4-6 ft. The leaves are coarse, long, and dark green. The leaf arrangement is alternate, leaf shape is linear, leaf tip is acuminate, and leaf venation is parallel. Some larger leaves have a conspicuous white vein running down the center. -Trunk/Branches: -Flower: Flowers bloom from May to September and are found as slender spikes with red anthers containing both male and female flowers on the same spike (monoecious). Purple stigmas are female while the orange stamens are male. -Fruit/Seed: Their fruit type is caryopsis. The hard yellow seeds are typically eaten by deer. -Roots: Gamagrass has fibrous roots and naturalizes with the use of thick creeping rhizomes and self-feeding. Growth Requirements: Light requirements include sun to partial shade. In fact, Gamagrass is better adapted to shade then most other grasses. Grows best in wet, boggy sites but will also tolerate well-drained soil if watered adequately. Uses/Fun Facts: Gamagrass is used as an accent plant in ground cover beds and as edging plants for ponds. T. floridana looks similar to T. dactyloides but has narrower leaves and is overall more compact. Wildlife us Gamagrass in diverse ways: birds may use the grass for cover and nesting, deer eat the grassís seeds, and butterflies such as Problema byssus feed on the foliage.
