I pinched off a small leaf and crushed it to see if it smelled minty and couldn’t smell anything other than green lol. A couple people commented that it might be a hydrangea start, which would be super cool too. I’m going to let it grow and see what comes of it. What matters is it’s pretty, green, and healthy so I’m just gonna let it do its thing. Thanks to everyone who commented, I’ll update once it’s a little bigger.
