Help needed to ID this hydrangea, not the name

I love the edges to this one but don't know how to even start with any identification.

Is there a specific word to describe the edges?

One more photo coming.

From a few feet away.

Thanks for any help at all.

In this picture from Garden Web they describe the petals as "saw toothed."

Edit: I notice that the picture is actually from Dave's Garden

Thank you, Sofi. I kept thinking scalloped but knew it wasn't right.

I appreciate your help.

Is Garden Web allowed to use DG photos?

I don't know....I found the picture when I googled "hydrangea petals toothed" and the source was a hydrangea thread in GW. I only noticed the DG watermark after I posted it here.

Anyway your hydrangea is beautiful and now I want to find one like it. I guess Altona is one to consider.

The watermark is there because you saved the pic on your computer and then uploaded it here--on the original thread on GW there's no DG watermark. Unless you have it set otherwise in your preferences, anytime you upload a picture here it will put a watermark on it saying that the picture is copyrighted by you...this is why if you have a picture on another site that you want people to see, it's best to link to it rather than uploading it, since it's really the person who posted it on the other site who owns the copyright to it.

Thank you for enlightening me, ecrane3.

Now I'm even more confused since not all serrata hydrangeas have serrated edges on the florets.

The photo on this pages does not appear to have saw toothed edges:

I'd appreciate any clarification. Thank you all.

The species name probably refers to the leaves, not the petals on the flowers.

Pirl I was able to find examples of saw toothed petals for both H macrophylla and H serrata.
(And another way to describe the petals, "deckle edged".)

macrophylla "Europa"

Love those photos, especially 'Blue Deckle'. Mine arrived from a west coast friend without any identification.

Thank you, Sofi, for all of your help. You've really been wonderful.
