Apparently the Latin name is in dispute, but yellow dancing ladies probably describes this one better than Oncidium anyway. The main flowering for this is late October but this year it’s flowered well in August. It’s an odd cultivar, with a twisted mass of pseudo bulbs and twisted leaves, and like its purple relative it clambers away from its origin and needs frequent re-setting. Bright indirect light, plenty of water, go light on fertilizer, and cold tolerant to 5C.
