|These epiphytic, tropical cacti originate from the Southeastern Brazilian rainforest and are grown for their showy, trumpet-shaped late winter to early spring flowers. Bristol Beauty bears 3 inch long, purplish red flowers with silvery throats. Leaves are fleshy, medium green, pendulous, and truncate. This plant prefers moderate water and humidity and a high potash fertilizer monthly during the growing season. When repotting, do so in a cactus medium. Light should be bright, but indirect. If grown outdoors in warmer climates, soil should be well drained and neutral to acid and plants should be located where there is shelter from pooling rain or drying winds. It is not uncommon for buds to drop if conditions become overly dry.
