A GUIDE TO NORTHEASTERN GARDENING: Prickly Pear Cactus: Native and Sustainable

Prickly Pear Cactus (Opuntia humifusa)

Welcome to This Month in the Garden! You may have encountered this plant growing in the more northeastern regions of the U.S. and been intrigued by it. Native to North America, the eastern Prickly Pear Cactus (Opuntia humifusa) is the only species of cactus widespread in northern gardens. A member of the genus Cactaceae, it is known for its showy bright yellow blooms followed by vibrant reddish-colored edible fruit in summertime. Its flat, paddle-shaped foliage consists of modified stems that are covered in small, hair-like spines, which provide the plant with protection from herbivores. This species has adapted to thrive in arid and semi-arid environments, making it a popular choice for xeriscaping and sustainable gardening.

Prickly Pears are low maintenance and thrive best with at least six hours of direct sunlight daily and planted in a well-draining sand/gravel based soil. These cacti also perform well in containers where the use of a standard cactus mix is ideal. Prickly Pears are drought-tolerant once established and require infrequent watering. Allow the soil to dry out completely between watering to prevent root rot. This plant can be propagated through pads or seeds. To propagate from a pad, let it callous over for a few days before planting it in soil. Roots should develop within a few weeks. It is important to note that while Prickly Pear are native to North America, they can become invasive in some regions, competing with other native vegetation. Properly managing this plant is important in maintaining an ecological balance.

Along with its attractive blooms and fruit, Prickly Pear Cactus serves many culinary and medicinal uses. Both the pads (nopales) and fruits (tunas) are edible. The fruits are sweet and can be eaten fresh, juiced, or made into jams and candies and the foliage is often grilled or boiled and used in Mexican cuisine. Prickly pear fruit was wildly eaten fresh and raw by native Americans, as some tribes made candy and chewing gum from the fruit or mashed the foliage into a type of applesauce. Medicinally, Prickly Pear Cactus extracts have been used for their anti-inflammatory and antioxidant properties. The Aztecs would use the juice from this cactus to treat burns and other ailments, while considering the plant to be sacred.
