Hypericum species

The diagonal one is a Rumex species.

I really don't think so. Here it would be H perforatum but I don't know which ones occur in MA.

H. reptans doesn't seem right ... this isn't a creeping, prostrate plant; it's upright, about 20"-30" tall. That's tall bearded iris foliage next to it.

I'd need to look more closely to see if its leaves have translucent speckling for perforatum, which is an introduced species here, though not listed as invasive.

Maybe punctatum,

Here is a species list from Connecticut Botanical Society. You will have to type in Hypericum for the search to show the species. I copied and pasted but it won't come up.

To check for the perforations hold a leaf up to the light as they're quite hard to see looking down on them.

Managed to run out for a quick check/picture before a front comes through ...

It's H. perforatum, it has the perforations:

Bingo.
