Is there anyway I can undo an action?

I had been diligently tending to the needs of a singular plant for the past several weeks, accidentally sold it when a card came up, and am now desperate to find some way to get it back. I know it’s a long shot, but… I don’t know, I was really hoping to see how that paid off, and now I just completely lost it.

Sorry for your loss… you can get the plant back, but you’d have to start all over again.
