This is a very pretty hydrangea, that changes colour. She is only a seedling and I think it would probably be wise to put her on in a slightly larger pot to let her get larger before you put it in the ground when the roots fill the pot.
Hydrangeas like a semi shady spot, they will grow in the sun as long as they are not baked all day. Cuttings are always worthwhile because put them in and forget about it and keep doing it and soon you will have a lovely garden full of plants.
