- 🌱 The aerial roots of Aranda orchids are capable of absorbing moisture directly from humid air, a characteristic inherited from their Vanda parent and reflecting their natural epiphytic habitat in tropical trees.
- 🌱 Aranda hybrids were first developed in the mid-20th century and remain among the most sought-after orchids by collectors due to their prolific blooming, large flowers, and remarkable color range.
