About 7 years ago I started some Epis from seed and have tracked the plants from year to year as they got bigger. This year I'm really frustrated as this year I was hoping for blooms but the nodes along the branches seem to be "blind". Usually you get the vein running from the center of the branch out to node where the bud appears. My branches seem to be completely smooth with no indication of a vein or bud. I didn't think to check but I think all the branches are coming from the center of the plant. No branches coming from the branches.
Obviously a lot of folks cross pollinate and grow hybrids to blooming stage but is my situation common. I don't think my plants are going to bloom at all. Is sterile the right word to use?
I will try to remember to post some pics of the branches over the weekend.
