My mom decided to get me a package of bacopa caroliniana, and i really don't have anywhere to put it besides somewhere in the foreground. I know they grow a lot and won't be suited for foreground, but they look so nice right now in the package when theyre only like 3 inches tall and tiny. Like a type of fancy grass or something. I was wondering if I could constantly trim them to not let them grow over ~4 inches, or if this would be unhealthy or just not work. Otherwise I really don't have room for it...
