Reminds me of Love You Kiss, a lacecap Hydrangea macrophylla & Kiyosumi (sp?), a lacecap H. serrata (but your leaves do not appear to be serrated).

from a google search, the coloration kind of looks like Miss Saori, but I'm not sure about the leaves. Also, Miss Saori isn't a lacecap...

Thanks for the info and the guesses about the plant. Doubt it would be hardy anywhere near my zone. I just thought I could pot it up and then bring it inside in the winter. It's getting to be about 60 degrees some days here. Could I take it outside in the shade during the day now or wait til it's warmer?

I did add my zone, thanks for the suggestion. ( Didn't zones used to appear on the old Gardenweb?)

Yes. Pot it up, bring it inside when it goes dormant (or if some wild downdraft in temps below the 20s suddenly approaches in the Fall). Then slowly re-introduce it to the outside. Maybe bring it to full shade that is however bright. For a few days. Then direct sun for a few hours for several days and finally, put it in its fina location... not too windy if you can help it... where it gets 2-6 hours of sun. Dappled sun is fine too.

Yeah about the zones. I noticed that too. They either did not "transport" that when they converted GW to Houzz or the conversion did not work.

luiz_pr: thank you for the information. Can I clarify a couple things that you said?
Would you expect it to go dormant before fall? Or were you referring to this coming fall?

Otherwise, am I correct to go forward introducing this to the outside (per your instructions) now?

Thanks again! I hope I can keep this alive, it's so pretty.
