New England Wildflower

Can anyone identify this wildflower growing in my backyard? I live in Central Massachusetts. Thank you.

 

Four O'Clock, Mirabilis

 

Mirabilis has fused petals and the stamens protrude. Maybe Phlox davidii?

 

Yes to phlox. The bees, butterflies and hummers love them in my garden.

Phlox paniculata.

Phlox davidii is not a valid species name... there is however a white-flowered cultivar of Phlox paniculata called 'David'?

 

Ha, thanks abgardeneer, yes I think I had purchased P. paniculata 'David' under that incorrect name once and it stuck in my head.

 

Thank you very much. It was driving me crazy as I had not been able to locate it anywhere online.
