I'm just curious, is there any way to remove plants? My strategy is that I have one 'hording world' where I move all of my Seedlings, and all of its plants are the Coniferous-Missile plants, but the rest are just breeding worlds to make more Seedlings. However, a couple worlds typically have one or two Coniferous-Missile plants left after I conquer them. I couldn't find a way to remove them, either, and though it isn't TERRIBLY awful, it still is a minor annoyance. So, can I change the type of plant or remove it altogether, somehow?
