Description
Pereskia grandifolia is a cactus that forms a shrub or small tree, up to 16.4 feet (5 m) tall, with a grayish-brown trunk up to 8 inches (20 cm) in diameter. The areoles are rounded, cushion-shaped, grayish, or brownish. The new twigs can have spineless areoles, while the trunk areoles may have up to 90 black to brown spines, each up to 2.6 inches (6.5 cm) long. The leaves are green, elliptic to ovate, and obovate-lanceolate and up to 9 inches (23 cm) long. The dense inflorescence develops at the ends of stems. The flowers are showy and rose-like, usually pink or purplish (but also white or tan) and up to 2 inches (5 cm) in diameter. They appear during warm months.
Hardiness
USDA hardiness zones 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
How to Grow and Care
As with many cacti, Pereskias can be almost ignored and still flourish. One of the major advantages that these plants pose as houseplants is their ease, and overwatering or overfeeding them is a bigger danger than neglecting them because it can damage their roots. If you repot them, remember to leave them alone for a brief period to avoid overstressing them and make sure to keep an eye out for common houseplant pests. Many of these cacti can't be grown as houseplants anyway due to their shrubby growth habit, and others are very rare, but when you do find out Pereskias can be good in cultivation.
They like dry conditions and don't need to be repotted often, but still, it is a good idea to refresh their soil by repotting occasionally. Be careful when repotting any cactus not to get hurt by their sharp spines and lift the plant from its mix and replace it in a new container before backfilling with soil. Do not water for a few weeks after repotting. See more at: How to Grow and Care for Pereskia.
