It reminds me of some yellow leafed paniculatas like Summer Snow and Yuki Gessho or Ghesso (not sure of the spelling)

Whatever it is, I doubt it would grow in zone 6. haha

Hint! it is a H. scandens......... can you identify the cultivar?

The name scandens always reminds me of the word "Scandinavian" for some reason... Hee hee hee. Isn't that a synonym for CH? CH has at least two yellow variegated (in Spring) versions, Miranda and Firefly.

'Fragrant Splash'?? If I'm right do I get a cutting?? LOL!

Hydrangea scandens
’Fragrant Splash’

"Hydrangea
scandens subsp. liukiuensis ’Fragrant Splash’ is a good stab at the correct
name for this plant. This selection of the species has speckles to irregular
blobs of light yellow variegating the narrow green leaves, giving the
appearance (to me) of some of the milder variegated Aucuba selections.
Otherwise, it looks nothing like an Aucuba. The stems are thin and splay about,
the lacecap flowers are white but sparse having the redeeming quality that the
fertile center is fragrant. Only to be cherished by the obsessed collector but
available here to all; we don’t judge your obsessions. Height to 4 feet or so.
Literature claims hardy in Zones 7-8."
