@Subrosa: There are actually a total of 5 Catts and 1 Dendrobium presently 'mounted' in the tree, plus 2 Vanda in baskets hanging from it.

I'll start a post about the tree and the thinks in it soon.
@silken: I know! The blooms be purple, or purple with a bit of white. I have it narrowed down to 2 color variations.
It's mostly cloudy with some wind here today. But I managed to take a few pics when the sun poked out.
1st: a pic of the plant from it's right side..
2nd: a pic of the plant from it's left side...
3rd: a pic of the "new" bud breaking from the dead/failed leaf...
