Kalanchoe crenata Perennial herbaceous ornamental succulent shrub with one or more erect stems, 0.3-2 m high, commonly called Kalanchoe, mother of millions, which never dies, can be confused with gladiolus and Bryophyllum pinnatum. Inflorescences appear in late fall and winter and feature rounded heads of long, tubular, orange flowers. After the flowers wither, all above-ground parts return to strong roots and bear seeds like dust.
