One of our neighbors are in the process of renovating their house and have taken out an old potted plant that they've said they dont want to keep anymore. I asked them about the plant and they didn't know what it was. From the looks of it, it appears neglected. Does anyone know what it's called?
I don't recognise the single flower, though someone else might, but the plant's determination to live despite its poor growing conditions probably should be rewarded! It's in way too small a pot, yet is obviously something that wants to get a good size - I'd wait till any flowering is finished, reduce the topgrowth by a third, then try to get it out of that pot - this may prove impossible because of the waisted shape which will prevent the rootball from coming out, so if possible, you will need to break the pot to remove it. Give it another pot (preferably one that isn't waisted, nor narrower at the top than at the bottom) 1-2 sizes larger than the rootball, using new potting soil, water well, watering ongoing as and when it needs it, and see what happens. It likely will respond by putting on new growth, and it may then become more apparent what it actually is, as well as producing more flowers next year, when an accurate ID should be possible.
You could try just planting it in the ground once its out of the pot, but it may be something that gets very large indeed, so it's best to ID it correctly before deciding to plant in the ground.
