Catharanthus roseus 'Titan Polka Dot'

many .. if not all .. are poisonous.. and the grapish looking fruits could attract young children ... and for sure attract birds who spread them for miles around... be done with it.. asap ... ken

" is that photo a bit photo-shopped? .. or was it taken at the precise moment of time at dusk with pink sky.. when you can capture this type of color pic? " It was edited with Photoscape, but I didn't adjust the colours.....I cropped it, increased the sharpness, and decreased the contrast a bit to keep the white flowers from overpowering the purple and pink ones. Otherwise, it was taken with a Sony mirrorless Alpha 6000, on a sunny day, sometime before lunch. Thank you to everyone for your help. I'd only ever previously seen the "mophead" hydrangeas.

Likely Oenothera biennis. If you look around there are probably some first year non flowering rosettes.
