If it didn't get so tall, I might consider letting that plant grow. When I was a new gardener, I did just that and ended up with spectacular looking 2-3 foot plants! LOL! Combined with its' explosive dehiscence, it's on the no-no list. The seeds would end up in beds in frustrating numbers, something I pull multiple individual sprouts of daily already, knowing that no plants have released seeds anywhere on the property for over a year. They're either coming in from wind/critters, or there's still a bank of them in the soil, &/or both. If it was possible to have just a few, I sure would! It's a very attractive plant, IMVHO. :+)
I do love O. crassipes & triangularis as a ground cover under shrubs. Tidy mounds of pretty leaves & flowers.
Gorgeous Ixora!!
This heavy shade spot isn't relevant to general lawn replacement, but there was just enough sparse grass to have to mow occasionally. I've pulled it up & put Callisias & Tradescantias instead. No more maintenance here except pulling occasional grass & tree sprouts. These plants don't even "want" me to mulch there. (So much easier to start in shade...!)
Forgot to paste a link originally. I like this one "weed," Portulaca amilis so much...
