Pot Size: 3.5"
Accepted Scientific Name: Epiphyllum hybrid 'Jan Killian'
Origin and Habitat:
Epiphyllum hybrids descend from rainforest cacti native to Central and South America, where they grow as epiphytes in the forest canopy. These plants anchor themselves on tree branches or within decaying plant matter, thriving in environments with filtered light, steady humidity, and excellent air circulation. The natural habitat provides them with a loose, organic medium and protection from direct sun. 'Jan Killian' retains these epiphytic qualities, preferring bright but indirect light, consistently moist yet well-drained soil, and humidity that mimics its tropical origins.
Description:
Epiphyllum hybrid 'Jan Killian' is prized for its spectacular large flowers, which measure 6 to 8 inches in diameter. The blooms display vibrant shades of orange and red, often blending toward magenta at the petal edges, creating a striking tropical display. The plant itself forms trailing, flat green stems that can grow 12 to 24 inches tall with arching or cascading growth up to 36 inches long. Its vivid blooms contrast beautifully against the green stems, making it an outstanding choice for hanging baskets and greenhouse culture.
Cultivation:
Zone: Best grown in Zones 10–11; overwinter indoors in cooler regions.
Temperature: Thrives in 18–30°C and should be kept above 10°C.
Growth rate: Moderate to fast, especially with warmth and humidity.
Soil: A free-draining, organic medium with pumice and orchid bark is ideal.
Watering: Keep soil evenly moist during growth and bloom periods, allowing light drying between waterings. Reduce watering during dormancy.
Fertilizing: Apply diluted cactus or orchid fertilizer every 2–3 weeks in the growing season to encourage strong flowering.
Light: Prefers bright, indirect light with protection from harsh midday sun.
Pests and Diseases: May be affected by mealybugs, aphids, or spider mites. Overwatering can lead to root or stem rot.
Propagation:
Propagation is simple from stem cuttings. Allow cuttings to callus before planting in free-draining soil. Roots usually form within a few weeks under warm, humid conditions.
