Description
Distribution
Ecology
Habitat
It likes sandy soils as well as disturbance. Kral (1983) says that it appears to have increased because of disturbance: "Areas in various stages of site preparation have an abundance which continues until the crowns of plantation pine close."[1] It is found in open sandy woodlands; it is most common in longleaf pine-deciduous scrub oak woods and oak-hickory-pine uplands wherever the soils are sandy. It is also found in sandy clearings, and sandhills.[1]. This has been found in habitats such as sandhills, upland pinelands that are annually burned, well drained uplands, and on slopes above a stream (FSU Herbarium). This is also found in human disturbed habitats such as a sandy fallow field (FSU Herbarium). This plant requires areas in habitats that have high light levels (FSU Herbarium) and is associated with areas that have loamy sand (FSU Herbarium). Euphorbia discoidalis is restricted to native groundcover with a statistical affinity in upland pinelands of South Georgia (Ostertag and Robertson 2007).
Phenology
It flowers from late August to frost.[1] This species has been observed flowering in August and September (FSU Herbarium).

Seed bank and germination
Fire ecology
This species is found in areas that are burned annually such as Longleaf pine-wiregrass savannas and sandhills (FSU Herbarium). It responds positively to fire. Kral (1983) writes "In naturally stocked uplands it increases as a result of woods fires which reduce competing woody vegetation." [1]
