Question
This is growing against a cinderblock wall in an urban area in MA. I can't get an id on iNaturalist or google photos lookup. I'd like to know both what it is (if possible) and if there's a name for this phenomenon going on with the leaves: the more mature leaves at the base have one shape and are in a group of three, but the leaves up the wall seem to have grown individually and then some are evidently split or in the process of splitting. It is attached to the wall with purpleish pads.
Answer
Dear waggledance, these appear to be the juvenile leaves of Parthenocisus tricuspidata (Boston-ivy). There are several cultivars of this species, and some of those cultivars even produce simple leaves that are not divided into three leaflets as is normal for this species. Best wishes.
