Description

Also known as eggleaf rosette grass, D. ovale is a native perennial graminoid that is a member of the Poaceae family. It has a rapid growth rate reaching a mature height of 1.7 meters on average, and a short lifespan. [1]

Distribution

D. ovale grows in the eastern United States, ranging from east Texas up to New York and Michigan, excluding West Virginia, Tennessee, and Missouri. [1]

Ecology

Habitat

D. ovale grows in a range of dry to damp soils, in sandy pinelands and woods and fields. [2] More specifically, D. ovale can be found in habitats ranging from open limestone glades, moist soil, longleaf pineland bogs, moist sandy peat, coarse sand habitats, abandoned fields, sandhills, and other sandy loams. [3] It has been seen to be more abundant in disturbed areas. [4]

Associated species - Aristida beyrichiana, Sorghastrum secundum, Schizachyrium scoparium var. stoloniferum [5]

Phenology

The species flowers in the springtime beginning in May, and continues to develop fruit throughout October. [2] Fruit has been seen in the months March through June and August. [3]

Seed dispersal

This species is thought to be dispersed by gravity. [6]

Fire ecology

The species does not have any tolerance to fire. [1]
