This plant has managed to live despite the other plants having long since moved to the compost pail. Oh, and did I mention how tough Christmas cacti are? This is evidence!
Unlike the desert cactus that Tucson is covered in, these succulents are epiphytic cacti. Christmas Cacti grow on other plants and rocks, not in the soil, in their native rainforest habitats. They are shielded from full, direct sunlight by the canopies of trees and plants, and they flourish in this environment.
Changing Color
Christmas Cactus can become orange, brown, or golden when exposed to much sunlight because they prefer shade from it. Yellow leaves may also be an indication of excessive sunlight or moisture. In Santa Barbara, my Thanksgiving Cactus was an outside plant that turned burgundy or purple in the winter as a response to the chilly weather.
Early in December, the Thanksgiving Cactus was lying on its side on the opposite end of the front porch when I first went to my client’s house. She is close to the Pacific, so at least some moisture is provided by the fog where she resides. That, in my opinion, is what has kept it going.
