Hmmm, climbing hydrangea?

This photos was taken in August/zone 5. I'm inclined to believe based on the leaves and blooms that this is a climbing hydrangea, but not being familiar with them, it appears to be structured more like a small shrub than a vine.... hence my confusion. Hopefully a wiser owl can confirm or contradict this. Thanks in advance for your help!

It's Hydrangea paniculata.

RE: Hmmm, climbing hydrangea?

I concur with carol23. The panicle shaped blooms suggest that it is a paniculata. Climbing hydrangea (Hydrangea anomala ssp. petiolaris) has white lacecap blooms (see the link below for a picture). It prefers to climb up a "surface" (tree, fence, etc) or spread on the ground, as opposed to creating a bush like the one on the picture.

Paniculatas will develop white panicle-shaped large blooms in June but some like Tardiva may bloom much later. After 3-4 weeks, the white blooms will change color. They are very cold hardy and will tolerate growing in clayish soils (up to a point). While some dwarf versions are being introduced lately, most tend to be 8-10 feet tall or more. Grandiflora (also known as Pee Gee) will get even taller and can be grown as a tree. The large blooms can be a problem sometimes when they get wet, causing an arching shrub effect.

Some well known paniculatas: Burgundy Lace, Grandiflora, Kyushu, Limelight (Little Lime is the dwarf version), Pee Wee, Pink Diamond, Pinky Winky, Tardiva, Unique, Vanilla Strawberry, White Moth, etc

Like many other climbing shrubs climbing hydrangea forms a mound where a vertical support that would take it higher is not present. But, apart from other differences from H. paniculata its stems angle downward rather than up.
