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.
