Mine opened yesterday and it's beautiful, too.

Layering is laying a stem on the ground and removing the leaves at a node (where the leaves exit the stem), then make a depression in the earth, lay down the clematis stem, cover with compost or earth, weight it with a brick. In a year you'll have a new clone of the parent. Be careful not to break the stem!
