This was one of my first Dendrobiums and I acquired it through EBay, and seller “orchidtn” on March 15, 2015. When repotting it into S/H, I discovered it was really two plants, potted together. (I have found out that this is frequently the case, to make the plant look bigger.) I potted both plants, and both bloomed, and held their blooms for three or four weeks.
They both have new growth. I will have to give these a winter rest period in the late fall.
