I have no idea
It could be something local. I use a coots mix soil, that I mixed up and let cook outdoors. I searched most of the plants listed in the seed mix, but didn't find anything that resembled it. Looks like its fixing to start flowering, so maybe that will give me a better idea. Guess I could download one of those plant identifying apps for my phone. The leaves look like an ivy plant, but I have almost zero knowledge of ornamental plants, other than super popular ones. It just looked to nice to cut down. It will give the ladybugs somewhere else to crawl around, and they'll probably like hanging out under those big leaves. There are a couple more just like this one with some of my plants in veg, but they are barely a quarter the size.
