Taking a cutting - mop-head hydrangea

[OverWyreGrower]

I really want a mop-head hydrangea - I will have a lovely space in my front garden for a shrub shortly (removal of some conifers)... I've seen loads around (gardens, parks etc)

Would I be able to grow one from a cutting? How do I do it??

Maybe this will help Hydrangea propagation
