Plants of this species and its hybrid, Bryophyllum ×houghtonii are known to be highly invasive, reproducing vegetatively from plantlets produced on leaf margins, and forming dense stands (giving the name mother of millions). Individual plants are relatively short-lived, dying soon after flowering.
Sometimes grown in horticulture under the names Kalanchoe delagoensis Ecklon & Zeyher, Bryophyllum tubiflorum Harv., and Kalanchoe tubiflora (Harv.) Raym.-Hamet.
