Description
E. heterophylla is a annual/perennial forb/herb of the Euphorbiaceae fmaily native to North America.[1] It has minute flowers that lack petals within a gland-rimmed and 5-lobed cup. This structure is on top of a leafy stem above white, red, and yellow leaves. Plant overall has milky sap.[3]
Distribution
E. heterophylla is found along the southern United States, from Florida to California, and disjunct in Kentucky. It is also native to Puerto Rico and the U.S. Virgin Islands, and has been introduced to Hawaii and the Pacific Basin.[1]
Ecology
In traditional chinese medicine, the whole plant of E. heterophylla was utilized to help treat irregular menses.[4]
Habitat
E. heterophylla is largely found in disturbed habitats. [5] It has also been recently found in waste areas in Virginia. [6] It's native habitat is canyons and uplands, though the plant is relatively scarce. [7] This species is also found in thickets, alluvial soils, glades, along railroads, open or rocky woods, and most often found in shady areas.[8] Specimens of this species have been collected from drying loamy sand of roadside, and along fences. [9]
Associated species include Sida rhombifolia, Chamaesyce sp., Boerhavia sp., and Solidago altissima.[9]
Phenology
This species generally flowers all year round.[5]
Seed bank and germination
E. heterophylla was found in the seed bank of an early successional site of a Neotropical dry region in Mexico.[10] It has also been observed to germinate in a wide pH range.[11]
Diseases and parasites
It is a host plant for the false spider mite Brevipalpus californicus.[12]
Conservation and Management
Euphorbia heterophylla is considered a noxious weed by the Florida Department of Agriculture and Consumer Services, Division of Plant Industry, and considered a plant pest by the South Carolina Department of Natural Resources, Aquatic Nuisance Species Program. Overall, it is considered to be weedy or invasive throughout the United States and Canada.[1]
