The rose Easter cactus is a bushy, epiphytic flowering plant that grows in the tropical rainforests of Southeastern Brazil. They can be found growing on tree trunks or on rocky ground. In its native habitat, it is threatened by urban development and deforestation. This species has an erect, bushy, and arching habit. It looks like a miniature version of the Easter cactus Rhipsalidopsis gaertnerii ); however, the rose Easter cactus has smaller joints and flowers. It is popular as an ornamental house plant and is a member of the cactus family (Cactaceae). The genus name, Rhipsalidopsis , comes from the word Rhipsalis, meaning "stem" and opsis , meaning "looking like." The specific epithet is Latin for "rose-colored." This plant thrives bright indirect light, and moist, well-drained, cactus potting mix, and high humidity. It is best to allow the soil to dry out slightly between waterings. During flowering, keep the soil moist, but after the flowers fade cut back on the frequency. It also prefers long periods of darkness, up to 14 hours. It can be propagated by stem cuttings. The stem segments are spineless, flat or have 3 to 5 angled concave sides, initially red and then become dark green, and the margins have 2 or 3 notches. The areoles are marginal and apical and have a few brown bristles. Its flowers are funnel-shaped, 1 to 1.5 inches long, and pink with rose-colored stamens. The fruits are yellowish, flattened, and spherical. The rose Easter cactus is ideal for new gardeners. It is low maintenance and has striking blooms.
