looking for ID help - wild "sunflower"?

[robrocke]

I'm looking for help identifying this sunflower-looking plant that's currently blooming in my yard.
The plants are ~4-5 feet tall.
I live on the Connecticut shoreline.
Is it native?
(Any chance it's ox-eye "false" sunflower, Heliopsis helianthoides?)
Thanks!

Yes, but it isn't the true wild specie. Looks like some kind of hybrid with all those extra petals.

Here's how the true specie looks.

The Oxeye Sunflower or False Sunflower (Heliopsis helianthoides) in the Sunflower Tribe (Heliantheae) of the Daisy Family (Asteraceae), is native to central and eastern North America. A number of cultivars and seed strains have been selected. The plant pictured is a semi-double form. There are a number of similar, semi-double cultivars of German origin including 'Goldgefeider' (or 'Gold Plume'), 'Sommersonne' (or 'Summer Sun'), Spitzentanzerin (or 'Ballerina') , and 'Venus'.
