A torch cactus is a South American cactus of the Echinopsis genus. It has incredible blooms that rise from the top of the cactus in varying colors, according to the Tuscan Cactus and Succulent Society.
Torch cacti have a burst of blooms in May and then again in mid-summer. They are able to bloom every 10 to 14 days over the course of a few months, with each flower lasting one to three days. Colors of torch cacti include red, white, purple, yellow and orange. Plants vary in size and shape, depending on the specific cactus cultivar, or variety, selected.
