Opuntia cespitosa, commonly called the eastern prickly pear,[1] is a species of cactus native to North America.
Description
[edit]Opuntia cespitosa is a prostrate succulent shrub, usually no more than 1-2 segments tall. It has large white spines, and a low layer of reddish-brown glochids, which break off in the skin if touched. It produces a yellow and red flower in late spring.[2]
Taxonomy
[edit]This species was historically included in a broadly defined Opuntia humifusa group, which is found further to the east. Opuntia cespitosa differs from Opuntia humifusa in its flowers having a red center.[3]
Distribution and habitat
[edit]The species is commonly found at the west of Appalachian Mountains and east of the Mississippi River, where it is found in the Midwest, Upper South and in Ontario.[1] Its natural habitat is in dry, open areas, such as outcrops, glades, and barrens.[1]
Invasive plant
[edit]O. cespitosa is invasive in South Africa. Some Hypogeococcus mealybugs are used as biological pest controls of this and other invasive cacti there.[4]
