Kalanchoe blossfeldiana 'Calandiva Red', also called Flaming Katy, is a flowering succulent in the Crassulaceae family native to the rocky highlands of Madagascar. It evolved in warm, dry conditions with bright light and minimal rainfall, giving it natural resilience to heated indoor spaces and low humidity environments.
The plant forms a compact, upright, clustering habit with thick, waxy leaves edged in subtle scallops and broad oval shapes. Foliage is deep glossy green and fleshy, retaining moisture for drought tolerance, with leaves often developing red tints along their margins under bright indirect light.
Calandiva Red produces fully double, rose-like blooms in vivid red that persist for weeks at a stretch. It flowers in late winter through spring in response to shorter days and cooler nighttime temperatures, and it can be encouraged to rebloom with proper light and temperature cycles. The blooms are odorless.
Rotate the pot regularly for even growth and keep it away from AC vents and heater drafts. Move it outside in summer to a sheltered, bright spot, but provide cover from rain and bring it back inside before temperatures drop below 50°F. Place it on a high shelf since cats, dogs, and small children should not nibble the foliage or contact the sap, which can cause skin or paw irritation. You can leave it up to ten days without water.

Kalanchoe blossfeldiana 'Calandiva Red' grows well in bright indirect light and grows steadily under office LEDs, though south-facing windows can scorch the leaves.
Water it every 10-14 days, letting the soil dry completely between waterings. Check for wilting to confirm the soil is dry.
Calandiva Red does best in fast-draining cactus or succulent soil blended with perlite to prevent root rot.
It prefers temperatures between 60-85°F and should never be exposed to frost or temperatures below 50°F.

It grows outdoors year-round in Florida, Hawaii, and the southernmost reaches of California, Texas, Arizona, Louisiana, Mississippi, Alabama, Georgia, and South Carolina. It also grows in coastal Nevada, the Oregon coast, and warmer pockets of those regions on a covered patio through the milder months.

Q: How often should I water Kalanchoe blossfeldiana 'Calandiva Red'?
A: Every 10-14 days, letting the soil dry fully between waterings. Check the soil by inserting your finger an inch deep; water only when it feels completely dry.
Q: Is it toxic to cats and dogs?
A: Kalanchoe blossfeldiana 'Calandiva Red' is toxic if ingested. Keep it on a high shelf away from pets, and avoid skin contact with the sap, which can cause irritation.
Q: What window direction works best for Calandiva Red indoors?
A: East or west-facing windows work well, providing bright indirect light without scorching. North windows can work with supplemental office LEDs, but south-facing windows often cause leaf burn.
Q: How do I encourage reblooming?
A: Calandiva Red responds to shorter days and cooler nights. Provide 14 hours of darkness per night for 4-6 weeks along with a slight drop in nighttime temperature to trigger a fresh flush of double red blooms.
Q: Can Flaming Katy survive a long trip without watering?
A: It can easily survive 10 days without water thanks to its fleshy, drought-tolerant leaves. Water it well before you leave and place it in steady bright indirect light.
Q: How large does it get?
A: Flaming Katy grows at a moderate pace and stays relatively compact, typically reaching 12-18 inches tall with a similarly wide spread depending on growing conditions and pot size.
