Description
P. dichotomiflorum is an annual graminoid of the Poaceae family that is native to North America.[1]
Distribution
Excepting North Dakota and Wyoming, P. dichotomiflorum is native to the United States, and has been introduced to British Columbia, Ontario, and Quebec. [1]
Ecology
Habitat
Moist habitats such as streams, flodplains, wet clearings, and waste sites are common environments to find P. dichotomiflorum. It requires full sun. [1]. Marshes are also common environments for the species. [2]
This grass is considered an indicator for anaerobic and compacted soil. [1]
Phenology
P. dichotomiflorum has been observed flowering August through December and in May and June with peak inflorescence in September and October. [3]
Seed dispersal
Seeds will fall off the stalks and into water and the ground, likely picked up by animals and dispersed. [1]
Seed bank and germination
Shallow flooding after seed dispersal is ideal for maximum germination. [1]
Germination will occur between April and May. [1]
Temperatures of 80F+ is ideal for proper germination.[1]
Use by animals
Small birds and ducks will was the seeds of the grass and deer will use it for browse. [1] It can be a major food source for ducks in a managed impoundment in South Carolina. [4]
P. dichotomiflorum has been known to cause photo-sensitivity to livestock as well as extreme nitrate poisoning. [1]
Conservation and Management
Planting a shade canopy will block the necessary sun light for P. dichotomiflorum is grow. [1]
