Golden Rain Tree

A couple of years ago, Cliff and I began admiring a pretty tree about three miles down the road; it was a nice, shapely thing.  It had lovely blooms at the beginning of summer.  Oh, I wanted such a tree!  
One day the man who owned that property was mowing his lawn, and I asked Cliff to stop and back the car up so we could see if he knew what sort of tree he had.  
"That's a Golden Rain Tree," he said.  "Have you seen it when it's blooming?  It's really pretty then!"  
I researched a bit, and found out it's a fast-growing, trouble-free tree.  Sounded perfect, so I called the nursery to find out if they had one.  

Isn't it cute?  It's been there since early spring, and has already grown some; it's better than six feet tall.  
It is not a native plant, which surprises me, because I saw them growing wild in abundance all through Arkansas.  It's easy to spot them when they're in bloom.  

Here's one I saw in an Arkansas village as we were pulling out of a gas station.  I just wonder how big mine will have to get before it starts blooming.  I wonder if I'll live to see it bloom.  Some of these tree species take their own sweet time about getting down to business.
