Den speciosum
Pat, in many areas speciosum & kingianum co-exist & bloom. In fact, there' s a
natural hybrid, Dendrobium x delicatum that is speciosum x kingianum. So, if your kingianum is blooming there's a good chance conditions are right to bloom the speciosum hybrid when it's ready. D. Ira Butler is 50% jonesii (biggish), 25% speciosum (big) & 25% tetragonum ("normal" sized). All components are from Section Dendrocoryne of the Dendrobes, & require broadly similar growing conditions, though tetragonum typically likes a bit less light. If you keep it & flower it, it should be rewarding. On Thu, 2 Aug 2007 06:31:46 -0400, "Pat Brennan" wrote: Not good, not good. I have a couple of flasks worth of plants of Den speciosum X Den Ira Butler that I was hoping to start seeing flowers on this winter. They already are the largest plants in my Den section. Sounds like it might be a few more years; more repotting and larger pots. My question is just how cold do they need to get to set spikes. I am growing them in a greenhouse which does not go below 62 F. The kingianum and its hybrids bloom fine in this greenhouse. I have a couple of flasks of Den speciosum X Den Ivory in 3 inch pots and am wondering if I should cut and run. There is always room for one more plant in the compost pile.
