Ok, so thanks to my mom and my Twitter friends, I think we’ve identified the tree as a mulberry.
Unfortunately, I had Frank chop it down this morning because I thought it was a weed (it grew ridiculously fast).
From what I read, though, it’s nearly impossible to kill, so maybe it’ll come back.
(I’m also going to try to get a cutting to grow. We’ll see.)
In the meantime, I’ve harvested the berries I could easily reach:
Anyone want to come over for a mulberry tasting party? I don’t have very many ripe ones, but the unripe ones are interesting, too. From here: “Unripe fruit and mature leaves have a white sap that’s intoxicating and mildly hallucinogenic.”
Perhaps this explains that crazy song about the mulberry bush.
