Family: Cactaceae. Origin: tropical America
Growing habits and cultivation
Perescia or Rose Cactus is a member of the cacti family from Tropical and Central America. Perescias are the only cacti with leaves. Being a cactus, it has spiny stems. In natural conditions it grows up to 10 feet (3 meters), but can be kept pruned or trimmed to a bushy shrub. It has woody stems, fleshy, pale green leaves, and creamy orange to pinkish flowers followed by funny yellow fruit which is not edible, but has a wonderful pineapple scent. Perescia needs full sun to partial shade, with a rich, well-drained soil. A soil mixture consisting of 2 parts peat moss to 1 part loam to 2 parts sand or perlite is recommended. During the spring and summer, the plants are kept moist and fertilized on a weekly basis. Since the plants are fast growers, you may have to keep them pruned to keep a desired form.
Potting culture
Perescias are easy to grow in a pot. They keep resonable size - under 3 ft, especially when pruned. Shade tolerant, it still prefers bright location. Regular fertilizing will encourage bloom.
Flowers and fruit
During spring-summer, the orangish-red, 2 in (5cm) blossoms open late in the afternoon. They are very showy. If fertilized, they create a waxy fruit up to 2" in diameter.
Propagation
Perescia is easily propagated from cuttings or seed in spring. Unlike other cacti, this plant is not succulent, and the cuttings should be planted in a moist soil mixture immediately instead of being left to dry out a couple of days. Seed sown in spring usually germinate within 21-30 days after planting.
Species
Perescia bleo (P. corrugata, P. aculenta)
Perescia Grandifolia
Perescia Grandifolia, unlike the Bleo, which has orangish-red flowers, has pinkish-purplesingle flowers. Grandifolia has very glossy, small, leaves while the Bleo has big and veiny leaves, flowers are in clusters.
