Kalanchoe blossfeldiana 'Yellow'

Bright, cheerful yellow flower clusters make Kalanchoe blossfeldiana 'Yellow' a popular choice for adding sunny color to indoor spaces and protected outdoor areas. This classic florist's kalanchoe features thick, scalloped, dark green succulent leaves and dense umbels of small, four-petaled flowers that last for weeks. It's a low-maintenance succulent that blooms in response to short days—making it a natural for winter and early spring color.

Plant Profile

Kalanchoe blossfeldiana (flaming Katy) is a compact, bushy succulent reaching 12–18 inches tall and wide. The 'Yellow' cultivar produces vibrant golden-yellow flowers in dense clusters above the foliage. Bloom time is naturally winter through spring, but growers manipulate day length to produce flowering plants year-round. The succulent leaves store water, making it drought-tolerant and forgiving of occasional neglect.

Secrets of Success

• Light: Bright, indirect light indoors; full sun to partial shade outdoors. Needs high light for best flowering and compact growth.
• Water: Water thoroughly when soil is dry to the touch. Keep drier in winter. Excellent drainage essential—never let sit in water.
• Fertilizer: Feed regularly during active growth (spring–summer) with balanced houseplant fertilizer. Reduce in winter.
• Humidity: Prefers dry air. Average home humidity is fine.
• Temperature: Avoid extremes. Ideal 60–75°F (15–24°C). Protect from frost.

Uses & Care

Perfect as a flowering houseplant, in mixed succulent containers, or in protected patio gardens (zones 10–11). To rebloom, provide 14 hours of darkness daily for 6 weeks in fall. Remove spent flower clusters to encourage new buds. Watch for mealybugs and root rot from overwatering.
