Coelogyne rochussenii

Coelogyne rochussenii is a spectacular tropical orchid species native to Southeast Asia. It is best known for its long, pendulous flower spikes that can carry dozens of fragrant flowers, creating a dramatic cascading display when mature plants come into bloom.

The flowers are typically greenish-yellow to olive-green with a beautifully marked lip, while the arching to pendant inflorescences can reach impressive lengths on established plants. This is a rewarding species for collectors seeking something unusual and visually striking.

Why Collectors Grow It

Few orchids create the impact of a well-grown Coelogyne rochussenii. Mature plants can produce remarkably long cascading flower spikes packed with blooms, making basket-grown specimens particularly impressive. While attractive year-round, this species truly shines when flowering, transforming into a curtain of fragrant flowers hanging beneath the plant.
