Looks nice! The ones I grow in containers don't spread out nearly that much! Most of mine (I have a bunch growing this year) are that magenta color like in your photo. But I have a few white, some pink, and a few yellow ones too. Supposed to have some salmon colored ones that are new to me, but none have bloomed yet. Yeah, I like 4 o'clocks.
My mom used to have them growing in front of our house in SoCal and those rascals were BIG! At least 4 ft tall....and that was AFTER my mom trimmed them down.
