The Torch Cactus (Trichocereus grandiflorus) is a species of cactus from the Patagonian Desert in Argentina. The Torch Cactus is notable for its huge display of dramatic red colored flowers that open in late spring. When adult Torch Cactus flower they can often produce displays of flowers that cover the top of the plant and can look like a carpet of red flowers from above.
Torch Cactus have become immensely popular in cultivation and are readily sought out by plant collectors. There are ever increasing varieties and colors of Torch Cactus that are being bred with intensely colored flowers that range from yellow through red and Magenta.
The Torch Cactus is frequently mislabeled and many other members of the genus Trichocereus and Echinopsis are frequently labelled as Torch Cactus to increase their perceived value, as the Torch Cactus is one of the most sought after members of the cactus family.
