Cymbidium dayanum

Cymbidium dayanum sprout from a 'dead' backbulbWhen I divide a specimen plant my experience has been that I don't end up with much in the way of larger pieces. I often end up with a large number of very small pieces. That's what happened when I divided a Cymbidium dayanum this spring.

Cymbidium dayanum grows from India through Southeast Asia to Japan. The plant grows in full sun and is cold to warm growing. This Cymbidium is an epiphyte blooming in summer and fall. The flowers are pendant and fragrant.

Cymbidium dayanum sprout 6 weeks agoSix weeks ago I was going through my Cymbidium dayanum backbulbs and decided that this one was dead. But when I removed it from the pot I found two sprouts.

Although sprouts are strong enough to break concrete if left alone, they can be broken off easily with sideways pressure. With a nod to the orchid gods, I repotted it as carefully as I could, fully expecting never to see either of these sprouts again.

Yesterday I found this tiny shoot just breaking the surface of the sphagnum. It's alive! It is going to remain unmolested in the greenhouse and be given a chance to develop a couple more generations of growth before separating it from the backbulb.

UPDATE: The orchid is spoken for.

Oncidium sphacelatum - Flower photo by Richard LindbergWould you like a free Oncidium sphacelatum? It is giant sized and grows long, pendulous spikes of 5 feet or more. As far as culture goes, this is considered a beginner plant, but not a good indoor plant because of the plant size and the length of the flower spike.


  1. It looks very much like my Onc Gower Ramsey. Sure enough, Onc. sphacelatum makes up 50% of the Gower Ramsey.
    Mine are in spike and the flowers just starting to open.
