Pereskia, the Rose Cactus

Pereskia is a genus of shrub-like cacti that are naturally found in tropical regions of Mexico and Brazil. The genus is believed to belong to ancient species of cacti that managed to keep their leaves and shrub like structure and did not evolve in to other cacti that we know today.

Though the genus of Pereskia is not much popular in horticulture, many members of this small genus make interesting specimen plants. They have woody stems with clusters of long and sharp spines. The leaves are fleshy and elliptic to oblong in shape. Most species produce large and showy flowers of pink color in late spring or early summer. These species vary greatly in size and growing habit. Some Pereskias can gain the height of 15 meters or more whereas some grow as small succulent shrub of 1 meter.
