Mother of Thousands 'Houghtonii' (Kalanchoe 'Houghtonii'): A Hybrid That Prolifically Produces Plantlets on Leaf Margins

Mother of Thousands 'Houghtonii' (also known as Houghton's Hybrid) is a vigorous, upright succulent with fleshy, lanceolate leaves that produce countless tiny plantlets (bulbils) along their serrated margins. These drop off and root instantly, forming carpets of seedlings. It grows 2–3 feet tall. In winter, it may produce clusters of tubular, pinkish flowers. A hybrid of Kalanchoe daigremontiana and K. delagoensis, it’s incredibly prolific and can be invasive in warm climates.
