Fun Facts
- 🌱 Flaming Katy is technically a short-day plant that flowers only when exposed to 6-8 weeks of nights longer than 12 hours—this is why it blooms reliably in winter and is a favorite holiday gift plant.
- 🌱 The white variety was developed through selective breeding; the original species (Kalanchoe blossfeldiana) produces vibrant orange-red flowers that are equally stunning.
- 🌱 Kalanchoe blossfeldiana is native to Madagascar and is sometimes called 'Madagascar Widow's Thrill' or 'Christmas Kalanchoe'—its foliage is non-toxic to most pets but can cause mild stomach upset if ingested in quantity.
