Cardiospermum halicacabum

I haven’t grown it. Looks like a fun plant to have though.
I grew hairy balls once (waiting for comments!!) but they weren’t a success. Grew too tall and leggy and only produced a few pods before frost got them.
Your post has made me consider having another go, but will pinch them to try and keep them bushy.
