You'd practically have to kill an epidendrum with an axe, they grow like weeds here in Oz. I have heaps and they flower and throw keiki's like crazy.
I have several exactly the same as that ebay one. It's a very strong grower and flowers on the same stem for months at a time. It's been known to be in bloom practically all year.
Wish I lived near you, I could give you a few of mine!
