pretty much almost all dendrobiums suffer from short life with me, though the most frustrating paph was that silly malipoense. I bought it in spike, and months later it finally flowered. For about three years the spike would grow up and up and up and after an eternity the bud would blast. Last time some scale got after it and I left them to eat.... no more problem
worst non-paph would have to be the dendrochilum cobbianum. I've had that almost the whole time I've been trying to grow orchids, and it's grown and grown and grown, been divided and chunks given to others, and grown and grown and grown, and never had a flower. I've tried many things and can't seem to get rid of it completely because it grows so well. One day I am convinced that the flowers will just explode out of it.... or it'll get sold or traded to someone. I can't throw away something that has grown so faithfully for so long.
