Kalanchoe blossfeldiana, commonly known as Madagascar Widow’s-Thrill, is an evergreen perennial succulent native to the rocky and sandy soils of Madagascar’s plateaus. It typically reaches a height of 30 to 45 cm (12 to 18 inches) and a spread of 10 to 50 cm (4 to 19.5 inches) within 2–5 years. The plant forms a bushy, rounded habit with moderate density and has a slow growth rate. Its foliage is green, shiny, and textured, remaining vibrant throughout the year. Kalanchoe blossfeldiana produces clusters of flowers in late autumn to early winter, with each bloom featuring four petals in a variety of colors including dark reds, pinks, oranges, golds, and whites. The flowers are particularly showy due to their bright colors and the contrast with the glossy green leaves.

Madagascar Widow’s-Thrill is valued for its long-lasting, colorful blooms and low maintenance requirements, making it a popular choice for indoor container plantings and as a seasonal outdoor plant in temperate climates. It thrives in cool, partially shaded conditions and requires protection from frost, preferring a minimum temperature of 10 °C (50 °F). This succulent needs well-draining soil and moderate watering, being careful not to overwater as it is susceptible to root rot. While it can be placed outdoors in summer, it should be brought inside before temperatures drop. It is important to note that Kalanchoe blossfeldiana can become invasive in some regions outside its native range, so gardeners should check local regulations before planting it outdoors.CC BY-SA 4.0
