Growth Stages

1

New Growth/Vegetative

4-6 weeks

Emergence of new pseudobulbs and shoots from the base or sides of mature growth; fresh green foliage unfurls

Maintain consistent moisture and warmth (70-85°F); provide bright light; begin regular fertilizing at half-strength

2

Pseudobulb Maturation

8-12 weeks

Pseudobulbs develop their full characteristic cylindrical form and leaves lengthen; plant gains vigor

Continue regular watering and fertilizing every 2-3 weeks with balanced orchid fertilizer; ensure good air circulation

3

Flowering Initiation

4-8 weeks

Flower spikes emerge from base of pseudobulbs, typically in late fall to early winter; buds form along developing inflorescence

Reduce night temperature to 55-65°F to promote blooming; slightly reduce water but do not allow complete drying; cease fertilizing

4

Blooming

6-10 weeks (successive blooms)

Star-shaped white flowers with greenish-white lips open sequentially; flowers are highly fragrant, especially in evening and night hours

Maintain warm days (75-85°F) and cool nights; reduce watering slightly; avoid moving plant during bloom; flowers last 2-3 weeks per bloom

5

Post-Bloom Rest

4-6 weeks

Flowers drop naturally; plant prepares for dormancy with reduced growth rate

Resume light watering and fertilizing to promote next growth cycle; maintain cooler winter temperatures; ensure dormancy period of 4-6 weeks

Fun Facts

  • 🌱 Brassavola grandiflora earned its common name 'Lady of the Night' because its fragrance is strongest after sunset and throughout the night, attracting nocturnal pollinators when daytime insects are inactive.
  • 🌱 This orchid is an epiphyte in its native habitat, growing naturally on trees in tropical rainforests rather than in soil, which explains why it thrives in loose orchid bark medium with minimal water retention.
  • 🌱 The genus Brassavola was named in honor of Antonio Musa Brassavola, a 16th-century botanist and physician, and contains only about 20 species, making it one of the smaller genera within the Orchidaceae family.
