Vegetative Growth
6-12 months per seasonPlant produces new flattened stems (cladodes) that grow longer and fuller, becoming increasingly vine-like
Water regularly during growing season. Feed with balanced or slightly higher phosphorus fertilizer every 2-3 weeks. Provide support structure if desired. Remove any dead or diseased stems.
Bud Formation
4-8 weeksSmall flower buds form along the stem edges, typically appearing in late spring or early summer after a cooler winter rest period
Maintain consistent temperatures (50-60°F nights in winter triggers blooming). Reduce watering. Avoid moving the plant. Ensure adequate phosphorus and potassium. Do not disturb stems with buds.
Flowering
One night per bloom; season spans several weeksLarge, cream-white fragrant flowers with delicate petals and prominent stamens open exclusively at night (evening to dawn)
Keep soil evenly moist but not waterlogged. Maintain warmth (65-75°F). The blooms are ephemeral and last one night only. Enjoy the experience! Expect sporadic blooms throughout the season.
