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.
