Rhynchorides Bangkok Sunset 1 Orchid Nature

The Rhynchorides (Perreiraara) Bangkok Sunset is a monopodial epiphyte orchid hybrid. It was registered in 2008 by Chao Praya Orch. and is a cross between Vandachostylis Thai Noi and Aerides houlletiana. This orchid is renounced for its beautiful colors that truly remind of an exotic sunset. Its small leaf span is also a plus for orchid enthusiast who don’t have a large growing area.


Blooms are very small, about 1.5 cm in diameter and present a waxy texture. The color is a unique blend of deep oranges that fade into strong yellow shades, while the lip is a striking purple color, making the overall inflorescence a beautiful sight to behold. The flowers stay compact and have the tendency to overlap each other.

Flowers are displayed on a thin flower spike of about 15-20 cm in length and each spike can produce between 20-30 flowers, or more. The blooms last for 6 to 8 weeks, depending on temperature. This orchid is not a sequential bloomer, once the flower fall the spike will not produce more blooms.

The flowers are moderately fragrant, smelling floral and clean. There is nothing bothering about the fragrance and can only be described as a refreshing, floral scent. This orchid releases its fragrance mainly in the first part of the day, towards the evening and night it slowly fades away.

The Rhynchorides Bangkok Sunset can bloom once or twice a year, although it doesn’t necessarily have a bloom season. While temperatures are warm and bright light is provided, it can bloom throughout the year.

The flower spike emerges from between the leaves, towards the top of the orchid, 3-4 side leaves down. It takes about 6 weeks for a flower spike to grow and open the flowers and usually this orchid produces 1 flower spike at a time and rarely 2 at the same time.  After blooms drop, the spike can be cut close to the stem, as it will not rebloom, or produce other plantlets.


The Rhynchorides Bangkok Sunset is a monopodial orchid that can become tall throughout the years, but its growth rhythm is slow. It produces about 3 or 4 new leaves within a year. Leaves are a medium to light green and the fan measures about 20 cm in length. New leaves sprout from the top of the orchid, but plantlets can appear at the base of the orchid. The leaves can get dark purple spots which look like freckles in bright light.

Roots can grow very long and while they are in active growth, green root tips are visible. When roots are wet they can have a green color, while when they are dry they are usually silvery grey. In very bright light the root tips can present a pink-red color.

It is usually grown bare root in hanging baskets and generally does very well in this set up. If pots are to be used, clay pots and a very coarse, well-draining media is preferred. The orchid can get top heavy, so stabilization might be needed for taller individuals.

Soft spots: stem and crown rot, root rot if the roots are not very well ventilated

Overall it is a hardy orchid that doesn’t fuss if its environment is less than ideal. Humidity is not an issue if the orchid is properly watered. It does like very bright light and direct sun, as long as the leaves are not permitted to overheat. If location is not a problem, it can be grown in a normal home with ease.
