Fun Facts
- 🌱 Dendrobium anosmum literally means 'without scent' in Latin, yet it is actually one of the most fragrant Dendrobium species—a naming irony from its historical botanical classification.
- 🌱 The flowers often emit their strongest fragrance in the evening hours, a characteristic adaptation in nature to attract nocturnal pollinators.
- 🌱 This species is an epiphyte in nature, growing on trees in tropical rainforests rather than in soil, which explains its preference for fast-draining orchid bark medium in cultivation.
