Rose cactus Pereskia
- Description
-
The rose cactus is a Genus of tropical cacti in the Cactaceae family with various forms ranging from a hedge, houseplant, shrub, and vine. It originated in Brazil. There are approximately twenty species that are native to the Caribbean, Central America, and South America. It is found in dry forests in its native habitat. The genus name, Pereskia, honors the French naturalist, Nicholas Claude Fabre de Peirese.
It prefers moist, well-drained soil in full sun or part shade and is drought tolerant. The flowers are ¾ to 3 inches in diameter and look similar to a wild rose. Most species are cultivated for their rose-like fragrant flowers and edible fruit. The leaves will drop if the temperatures are below 50 degrees F.
Some species can be grown in containers with direct sunlight and a well-drained potting medium. The rose cactus may require regular pruning if it is a houseplant. It should be watered regularly in a container when it is growing and has leaves.
The rose cacti have spines and floral cups like other cacti. However, they are the only cacti with persistent non-succulent leaves. Many scientists believe the rose cactus is the ancestor of the Cactaceae family, and other cacti lost their leaves as they adapted to dry conditions. It can be propagated from seed or fresh stem cuttings planted in soil. It can also be rooted in water.
