In the school grounds opposite my house is a small Sorbus about 3mtrs. It is still covered in very pale pink berries even in February . Any ideas what it might be. Also I have a Sheerwater Seedling Sorbus in my garden which is a bit of a disappointment to me. It has been there for about 7 years and is growing well but has no Autumn colour at all. The leaves turn dark brown and fall. It was recommended for is colour . What`s gone wrong?
