Jasminocereus thouarsii is a columnar cactus that can grow up to 16.4 feet (5 m) tall. It has tree-like form with a thick stem that usually separates into several branches. The stem is deeply ridged and bears clusters of long spines which may be colored white, yellow, reddish-brown or black. The scientific name is a reference to its attractive, large, jasmine-like flowers which have white and yellow petals. The plum-sized fruits grow on the trunks and bright red when ripe.
USDA hardiness zone 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
How to Grow and Care
Like most cacti, Cereus are fairly low-maintenance and hardy. Make sure they receive enough water without becoming waterlogged, especially during the summer, and fertilize them for best results. If the roots have become black or overly soft, the cactus could be experiencing root rot – cut away the affected parts and replant. Like all cacti, give them lots of direct sunlight, especially during the summer. Well-drained soil is best, and most Cereus perform well in a soil that contains some organic material. Some recommend avoiding a soil that contains sphagnum moss, though – it can make the cactus vulnerable to root rot.
Cereus cacti propagate quite easily from cuttings; simply sever a branch and replant in moist, well-drained soil. It helps to allow the cut end dry out and harden before you replant it; this makes it easier for the new cactus to form roots… – See more at: How to Grow and Care for Cereus
