Help me identify this plant, the flower was like a small square parcel before it opened.

Good afternoon & welcome to GT. This is a balloon flower

Looks like balloon flower

Thank you for your response, the flower was like a little origami box before it opened, the only thing I've seen similar is Chinese lantern plants, but this was more square. We only moved in 5 months ago 3 weeks before lock down, we are just letting things happen and new plants keep appearing.

Hi Colin, I agree with Joan, its baloon flower. If you want to reply to anyone, remember to put @ and then their username or they won't see your reply i.e @joanboston

@joanboston I've been googling it but can't find the exact variety with the 4 points and square before opening.

Sorry I meant balloon not bellflower 🤣🤦🏼‍♀️
