Disocactus speciosus is the remarkable epiphytic Sun Cactus from the jungles of Southern Mexico and Guatemala.
Related to the more common Aporocactus flagelliformis, Rattail Cactus, which have more recently been moved into the Disocactus genus. Similar flowers, but the Sun Cactus is much more spectacular.
Pendant stems will grow more than 3ft. in length. Easily hybridized, there are a number of cultivars out there with various and different equally remarkable flower colors.
We recommend that you grow them indoors.
