Queen of the Night

Epiphyllum oxypetalum

flower

Queen of the Night is a spectacular night-blooming cereus cactus prized for its large, fragrant white flowers that open only after dark and typically bloom for just one night. This epiphytic cactus naturally grows on trees in tropical and subtropical forests and develops long, flattened, leaf-like stems rather than typical round cactus arms. The blooms are a gardening spectacle, often measuring 6-12 inches across with intoxicating fragrance.

Growth Stages

1

Establishment

6-12 months

Young plant develops long, flat, leaf-like green stems with aerial roots visible. Growth is relatively slow initially

Keep in bright, filtered light. Water moderately. Provide support or stake for vertical growth. Begin fertilizing lightly in spring

2

Vegetative Growth

1-3 years

Plant produces increasingly long stems, reaching 1-2 feet or more. Stems may branch and develop trailing sections. Plant gains size and maturity

Maintain consistent bright, indirect light. Water when top inch of soil is dry. Feed every 2-3 weeks with diluted balanced or high-potassium fertilizer. Support with stakes or trellis as needed

3

Bud Formation

4-8 weeks before blooming

Flower buds appear along stem edges, typically in late spring or early summer. Buds are initially green and elongated, gradually enlarging over weeks

Do not disturb or move the plant once buds form, as movement can cause bud drop. Maintain consistent watering—neither too wet nor too dry. Continue light fertilizing

4

Blooming

Several nights over 2-4 week period

Large, creamy-white flowers with multiple petals and prominent yellow stamens open in evening and typically close by morning. Flowers are highly fragrant, often smelling of vanilla or jasmine. Blooming typically occurs in June-July

Allow flowers to open naturally in the evening. Take photos or enjoy in person during the night bloom. Do not cut or disturb flowers. Maintain normal care; most plants produce multiple blooms over several nights

5

Post-Bloom Rest

Fall through late winter (3-4 months)

After blooming concludes, plant enters dormancy period. Growth slows, stems may appear less vigorous. Some leaf-like structures may develop at base

Reduce watering significantly in fall and winter. Provide cooler temperatures (50-60°F) if possible to promote flowering. Hold back on fertilizer. This winter rest period is essential for next year's bloom initiation
