I have several locust trees in my front yard. They grow like weeds. So much so, that I will be digging up several out of the yard to give to my cousin.
They are late to leaf out. This spring I had two slightly misguided but well-intentioned people, on separate occasions, tell me I should cut those dead trees down. Are you kidding? Check them out.
The tree itself does look craggy and old man-ish.
The leaves and flowers though are delicate and lacy. The flowers have a heavenly aroma, that I don't find cloying like lilac can tend to be. Don't let the lacy bit fool you though, it also bears 1/2" to 1" thorns on the branches.
One day a couple of years ago, I walked outside to head to the mailbox, and heard a loud buzzing. I couldn't figure out where it was coming from, so started down toward the gate. The buzzing got louder. I realized that the locust trees were covered in thousands of bees, all busily working away. I'm glad the trees help feed the local bee population.
