Description
Common Name: Heller's rosette grass
Synonym Name: Panicum oligosanthes Schult.
Dichanthelium oligosanthes is a perennial graminoid. It tends to form dense tussocks of many stems (FSU Herbarium).
Distribution
Ecology
Habitat
It can live in Foard and Lawton soils, which are both grassland soils.[1] It can be found in undisturbed areas.[2] D. oligosanthes var. scribnerianum can tolerate hot summers, cold winters, minimal precipitation (826 mm per year), and moderately strong surface winds.[3] It is commonly found in open woodlands.[4] It can be found in tallgrass prairie.[3]
Phenology
It flowers from early to mid season.[5]
Seed dispersal
Fire seems to stimulate the seed bank.[4]
Seed bank and germination
Fire ecology
It responds positively to fire. It increased in distribution and abundance following an early dormant-season fire.[4] Dichanthelium oligosanthes var. scribnerianum found in uplands and lowlands responded positively to summer burns but negatively to spring burns in the long run (more than 10 years). However, D. oligosanthes found in the canopy cover declined with both burns.[3]
