Great Josh and you beat me to it. My Flying Dragon flowered for the first time too and wanted to post it but here it goes piggybacking on yours. I think mine is also 5 yrs old or may be 6 at most. I have regular PT too but that is about 3 yrs now.

The FD is wickedly beautiful plant. Grows slow. Kept it outside from day 1 in zone 6b with a bit of winter protection. It drops all or most of its leaves. The PT seems to hang on to some. When I prune these I have to make sure they do not go into the compost pile. Those thorns remain wicked forever.

And here it is leafing out all over with a few flowers near the top.
