|These epiphytic, tropical cacti originate from the Southeastern Brazilian rainforest and are grown for their showy, trumpet-shaped flowers. From late fall to mid-winter, Wintermdrchen bears very pale pink, 2 1/2-3 inch long flowers, which turn almost white in winter. 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. 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.
