Description

Pereskia grandifolia is a shrubby cactus or small tree with a grayish-brown trunk and rounded crown that grows up to 8 inches (20 cm) in diameter. It grows up to 16.4 feet (5 m) tall. The areoles are rounded, 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. Leaves are green, elliptic to ovate or obovate-lanceolate, and up to 9 inches (23 cm) long. The dense inflorescence develops at the ends of stems. Flowers are showy, usually pink or purplish (but also white or tan), and up to 2 inches (5 cm) in diameter. They appear during warm months.

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 find out Pereskias can be good in cultivation.

They like dry conditions and don't need to be repotted often, but it is still a good idea to refresh their soil by occasionally repotting. 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.
