New, distinct and stable cultivars of double-flowering Kalanchoe interspecific hybrids are disclosed. Double-flowering Kalanchoe interspecific hybrids produce one or more flowers with at least 5 full or partial petals per flower. Double-type K. aromatica x K. blossfeldiana, K. grandiflora x K. blossfeldiana, K. laciniata x K. blossfeldiana, K. pumila x K. blossfeldiana, K. marmorata x K. blossfeldiana, K. porphyrocalux x K. blossfeldiana, K. jongmansii x K. blossfeldiana, K. pinnata x K. blossfeldiana and K. daigremontiana x K. blossfeldiana are disclosed. The double-type flowering characteristic has been combined with many desirable Kalanchoe traits including different flower colors, growth characteristics and plant habit. Methods for the reliable breeding of the double-type characteristic into diverse Kalanchoe genetic backgrounds, as well as methods for increasing the number of petals per flower, are disclosed.
