Fun Facts
- 🌱 Tolumnia urophylla was formerly classified as Oncidium urophyllum and is sometimes still sold under that name; the genus Tolumnia comprises the smallest orchids in the Oncidiinae subtribe.
- 🌱 The flowers emit a delicate, sweet fragrance that intensifies in the evening hours, and some blooms can flower repeatedly on the same spike over several months with proper care.
- 🌱 This orchid is native to humid tropical forests where it grows as an epiphyte (on tree branches) rather than in soil, which is why it requires excellent drainage and high air circulation to thrive.
