Flaming Katy (Kalanchoe blossfeldiana): Care Guide for Long-Lasting Blooms

Flaming Katy (Kalanchoe blossfeldiana)

Flaming Katy is a popular flowering succulent with clusters of tiny, vibrant flowers (red, pink, orange, yellow, white) above glossy, scalloped green leaves that redden in sun. It blooms naturally in spring but can be forced year-round. Easy care, but reblooming takes effort—or just propagate new plants!
