Fun Facts

- 🌱 The striking pansy-like appearance of the flowers is an evolutionary adaptation to attract specific bees and insects in their native cloud forest habitat; the intricate markings act as 'nectar guides' pointing pollinators to the flower's center
- 🌱 Miltoniopsis species have been extensively hybridized since the 1800s, creating thousands of spectacular hybrids; pure species like M. roezlii are now relatively rare in cultivation and prized by collectors
