Red kalanchoe (Kalanchoe) is one of about 125 species of tropical, succulent, perennial flowering plants in the Crassulaceae family. Normally cultivated as ornamental houseplants and rock or succulent garden plants, kalanchoes are popular because of their ease of propagation, low water requirements, and wide variety of colors. They can grow to 2 feet in height and width with blossoms that are typically borne above the leaves in large, upright clusters of five petals with yellow stamens. The flowers can last anywhere from seven days to a month. The large, smooth, leathery leaves are 2 1/2 inches long and 1 1/2 inches wide, with edges that are lightly scalloped and often slightly tinted red. To maintain this plant, thoroughly water it, and then allow the soil to dry out; it will not thrive in moist soil that is not allowed to dry out between watering. The colorful kalanchoe is attractive to bees, butterflies, and birds.
