Any idea about the kind of cane dendrobium is this?

I found leaving mine (which look like yours unflowered) like the light and cool to cold (on my deck temps down to low 50's) in the fall, and they have bloomed every year ( maybe the last 3 or so) since doing the cold therapy.

Oh ok, thanks for the input.

I would try to keep these above 55F. Den-phals are typically warmer growers.
