I have an Onc Rosey Sunset 'Pink Bouquet. It just finished blooming about 2 weeks ago. The spikes have not turned yellow or dried out and now it looks like it is trying to rebloom from those 2 spikes or grow a couple of Keiki;s, Don ;t know how to post photos if some one can help me. Thanks
It's also not usual for Oncidiums to bloom on previously bloomed spikes - some genera in the alliance do; Tolumnia and Psychopsis, that I know of - but it seems unlikely for yours ... BUT, I certainly don't know everything!
