The wild species of Hydrangea arborescens has lacecap blooms. Annabelle should be the named used when the blooms resemble round balls or mophead but I often see the lacecap version called Annabelle too. To me, that is not correct but, sigh, oh well.... I kind of like this version better.

Give it morning sun, afternoon/evening shade. Maintain 2-4" of organic mulch (no rocks) at all times. It is almost summer so increase the amt of water one notch higher.

Do you think this one will bloom on new wood or old?

New.

Thank you for the info! It gets morning sun until 2pm. I'm thinking that might be too much?

It will let you know if it is getting too much sun or too little water if the leaves are going limp. In the case, give it a bit of shade for now and then move to a spot with morning only sun. Mine has sun until about 2 also and is fine, but I am much farther north.

Mulch the soil around it to help regulate soil moisture.

Bees just love the lacecaps flowers here too! It is the fertile flowers.
