What is pereskiopsis?

Pereskiopsis: An Overview

Pereskiopsis is a genus of cacti, unusual because they possess leaves, unlike most other cacti. This characteristic makes them valuable in horticulture, particularly for grafting.

  • General Characteristics: They have true leaves and spines, resembling shrubs or small trees more than the stereotypical cactus. They are native to tropical and subtropical regions of the Americas.

  • Use in Grafting: Pereskiopsis is highly prized as a grafting stock, especially for smaller, slower-growing, or more difficult cacti like Ariocarpus and Astrophytum. Its rapid growth promotes faster development of the scion.

  • Growth Habits: Pereskiopsis exhibits rapid growth, often needing frequent pruning when used in grafting. They require warm temperatures and are not frost-tolerant.

  • Cultivation: Pereskiopsis are relatively easy to cultivate. They prefer well-draining soil and regular watering during the growing season. They can be propagated easily from cuttings.

  • Species: Several Pereskiopsis species are used in cultivation, with Pereskiopsis spathulata being one of the most common. There also exist hybrids within the Pereskiopsis genus which are widely used.

  • Potential Problems: They are susceptible to pests such as spider mites and mealybugs. Overwatering can lead to root rot.
