Yeah the one I mentioned is about 20 feet tall now too. Beautiful trees, the leaves are the size and shape of pine needles, except they are deciduous. We have a big one in the back, over 100 ft. tall, and the 1st year we were here I thought something was wrong with it when it turned yellow then brown, lol.
I mowed that front area in the pics on Saturday, and we have a major crop of cicada killers this year. There has to be 50 to 100 holes on that side where they make their nests. Needless to say I mowed it at a high rate of speed. They were annoyed to say the least. I had done my research and only the females can sting, although they say it's not as bad as a yellowjacket sting. Still, lol.
