Gardeners' Notes:

One of the most cultivated orchids in Brazil, this beauty comes from the humid brazilian coastal rainforests. Itīs an epiphytic herb, with smooth, somewhat flattened, elliptic pseudobulbs, bearing a pair of ribbon shaped leaves on the base, and another on the top of each pseudobulb.

The inflorescences are panicles that come from the axil of the lower leaves, bearing tens of small flowers. The flowers have yellow with brown stripes and short petals, and a large yellow labellum with a red spot and some calousities in the middle. The flowers wave by the wind like tiny dancers in golden dresses.

It needs a supporting tree, or fiber to be planted on, keep consistently moist, and light, tolerating a few hours of sun per day. Keep it from air currents and frost free. This is an easy tropical orchid to grow, and doesnīt require fertilizers for long times. I have two of them blooming right now. In the Botanical Garden they have an awesome plant with larger inflorescences.


This plant has been said to grow in the following regions:

Brea, California
Lecanto, Florida
