I'm a new homeowner and love the hydrangeas in my back yard. Last summer we just moved in to the house and didn't have a ton bandwidth to landscape. This year we've been doing a lot of landscaping and I need some help identifying/working with this hydrangea. This hydrangea seems to be a mix of a variegated one and regular one? I first thought it was two placed too close together, but looking at the leaves (see picture 2), they are the same plant. This hydrangea didn't flower last year. They had one bud that never fully bloomed. Any advice?
