Plant ID - is it a tree?
Hello everyone. Can anyone tell me what this is/might be? I found it growing in my mum's large pot of lilly bulbs she had put out the year before last. The lilly had babies and they were all tangled up with this more sturdy plant. It was very diffifcult but we untangled most of them and moved those into a different tub. This shrub/tree (?) looks to be growing healthily so I have temporarily put it in this pot while I work out what it is. I might put it in the ground depending on what it is. It had a very big root ball and a plethora of long stringy fibrous roots. I didn't plant it. My dad has a tendency to put fruit seeds into my mum's patio and houseplant pots. Like that we have a grape vine and a did have tamarind plant too. He doesn't recall though. Could it be an apple tree from seed? Or is it something else?
