Beautiful, Sherri. Those nobile type of Dendrobium do go dormant in winter, and like to stay dry and cool, so they like the colder winters for sure. I wonder if maybe your Aunt's plant was dormant when you got it? They do look pretty dead, with no leaves and just the fat canes hanging all over. But then the flowers appear like magic on those canes.
I have 3 plants of Den. anosmum, another dormant type like this. They're just starting to think about putting out buds.
