ID for large, bushy mallow
Hi, can anyone please help me with an ID for this plant. It's sprung up from either a bird dropping a seed or a dormant seed from one of my sowings.
It's a very large, bushy plant with a multitude of branches and a mass of small flowers that are either mallow or something closely related.
It doesn't look to me like other tree mallows I've seen as the flowers are very small, only a few centimetres in diameter. I could be wrong about that as it's only in its first year of growth.
It's a magnificent, healthy specimen whatever it is and I'd like to make sure it stays by looking after it properly.
