4-6 weeks

Young plant develops compact rosette of thick, waxy green leaves

Keep in bright light, water sparingly, maintain temperatures 60-75°F, avoid root disturbance

2

Vegetative Growth

6-12 weeks

Plant fills out with dense foliage, leaves may develop reddish edges under bright light

Maintain bright indirect light, continue minimal watering, avoid fertilizer or use diluted solution monthly

3

Bud Formation

4-6 weeks

Small green buds begin forming at stem tips in response to short day length

Exposure to 6-8 weeks of cool nights (50-60°F) and short days triggers flowering; reduce watering slightly

Flowering

4-8 weeks

Dense clusters of small, bright white star-shaped flowers bloom profusely, typically December-February

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.
