Chances are they go in the dumpster. I worked in the office for a huge nursery. Any started plants that didn't pass muster were dumped. Some employees and many of the locals would go collect those plants and take them home to plant.
Our HD store (and Walmart, too, I think) just let a nearby large nursery put out all of the live plants and manage them (watering, tossing the dead ones, and removing the left overs when cold weather gets here, etc.). The stores do not discount the plants 1 penney when the planting season nears end.And true enough I've been in HD several times and watched them throwing wilted plants into carts to toss in the dumpster. I always wished they would let me dumpster dive but no such luck. Happy gardening everyone.

I have asked.
The store just makes a little off of the sales by providing the floor space.
