Do potted plants count as personal belongings?

[Stacy Tring]

I am buying a property that has potted plants outside that I do not want to maintain. See attached picture for an idea of how extensive we are talking here. Not a ton, but this is on all four sides and in front, so all in all about 20 or so potted plants, and I simply don't want to deal with hauling all of it away.

Most of our sales contract is based on a standard template, which does say that the seller must remove their personal belongings, but there is disagreement as to whether the potted plants fall under that clause. I feel that since the plants are not planted into the ground and are freely movable, they do count as personal belongings that the seller is responsible for moving. Thoughts?
