Lovely! It's a hydrangea of one sort or another
Cut last year's flowerheads off just above a pair of fat green buds - scatter some Fish Blood and Bone or Rose Fertiliser on the soil around it and hoe it in lightly.
When it flowers we'll have a go at telling you a bit more about it.
It likes to be in semi-shade but can cope with sun as long as the soil doesn't dry out, and it strikes easily from cuttings.
