Taxonomy

Some botanists treat this cactus as a variety of '' O. compressa'': hence ''O. c.'' var. ''humifusa'', or a synonym of ''O. compressa''. Those recognizing this species treat '' O. rafinesquii'' as a junior synonym.


Distribution

This species naturally occurs along the East Coast of the United States, including on barrier islands from the
Florida Keys The Florida Keys are a coral cay archipelago located off the southern coast of Florida, forming the southernmost part of the continental United States. They begin at the southeastern coast of the Florida peninsula, about south of Miami, and e ...

. Eastern prickly pear is found is scattered locations from New Mexico and Montana eastward, and is one of two cactus species native to the eastern United States, along with the related '' O. cespitosa''. Since eastern prickly pear grows in hot, sunny locations with thin soil that does not hold water, it is found in shale barrens, which are accumulations of thin, flat, eroded sedimentary rock on steep slopes with southern exposures - essentially a desert microclimate - in the Appalachian Mountains.


Habitat

This plant is very intolerant of shade and instead thrives in sunny, hot and dry environments with well-draining, sandy
soil Soil, also commonly referred to as earth or dirt, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Some scientific definitions distinguish ''dirt'' from ''soil'' by restricting the former te ...
. ''O. humifusa'' will grow in open areas in sandy, rocky and coastal scrub habits. It is capable of surviving cool winters unlike many cacti, although harsh winter storms are known to cause habitat loss.


Uses

The fruits are edible, but have small spiny bristles. The pulp can be scooped and the seeds strained out to make syrup or jelly. The seeds can be briefly roasted and ground into meal. Young cactus segments can be roasted to remove spines, then peeled and sliced to be eaten like string beans; alternatively, they can be deep fried. The leafy segments can be peeled and chewed for emergency hydration.
