My childhood past time of tree climbing is finally paying off. I got stuck up in a Catalpa tree once and had to be talked down by the security guy in the Remington Arms woods. I may not know what something is, but I know what it's not. From there I use the Sherlock Holmes method.
Have you noticed if this beautiful tree makes any type of seed pod?
Oh, never mind.
Skip that question; just noticed the tree is in NM and you are way up in MN. Blame the dyslexia. NM/MN looks the same when I'm tired.
