Which genus of flowering plant is shown in the picture?

An extremely popular free flowering house plant in the UK, however it does well outside during the summer months. It's extremely easy to propagate. Just pop a broken stem into water and roots will start to develop within a few days to a week. Don't leave them outside if you're susceptible to cold weather. It's known by its common name in the UK as Busy Lizzie. Most probably because it's one of the easiest plants to propagate.

Demure, IDK either but it’s a cool picture!

Globular Martian, I'm not sure what I'm looking at im your photo. My photo and name are from a question in this game.
