They are everywhere, much like the Bradford Pear trees back in the South.
So, being the curious person I am, I plucked off a leaf and flower cluster and stuck them in my bag to take into work. I just knew someone at work would know what kind of tree it is.
Of course, since I have a 'specimen', it has to go into my journal.
The type of tree was on the tip of everyone's brain and we finally figured out it was a Linden Tree! And I wasn't quite wrong referring to it as a lemon-lime tree. In England, they are sometimes called Lime trees.
Then as it happened, on the day I was running around the library trying to figure out what kind of tree it is, a tourist came in and asked. Luckily, it was AFTER I had my question answered.
Oh, the trivia I stuff into my tiny brain!
