obnoxious plant
A plant that is so stupid and ugly it makes you want to yell at it. It’s the kind of plant that you think is trying to be cool but it’s not.
That bush is so perfectly trimmed, it’s like it’s trying to be a showoff.
That tree is so messy, it looks like it was hit by a tornado.
That flower is so obnoxious, it’s like it’s trying to take over my brain.
