Hi Faye 'grafted' means that the 'scion' (in other words the actual fruit tree) has been grown on a rootstock of something different, in this case it is a rootstock which will keep the complete tree small. 10 foot is actually small for any fruit tree particularly over 10 years. You will be able to prune to keep to the actual height that you want.

Aha! Thanks for the translation :-)

If you want to grow it in a pot, ask the garden centre/supplier what the name of the rootstock is - Pixy would be the best for pot culture, but it might be on St. Julien A, and they get slightly larger.

Good point Bamboo

Thank you. There are a couple of cherry trees I like the sound of that are grafted onto a colt root stock, does that sound ok? I shall ask about the plum and see what they say.

I would suggest you look for cherry trees grafted onto Giesla 5 as Colt will get to 4 metres easily whilst Giesla 5 should keep the tree around 3 metres - 10 foot.
