I would like to find an adequate substitution for the beautiful but invasive, Mexican Feather Grass (Nassella tenuissima). I was thinking about using Purple three-awn (Aristida purpurea) seen below. Anyone have experience using this or have another idea for a substitution?
Pennisetum?!?!?!? OMG!?!?!?!?! It's even more invasive than Mexican Feather Grass. Vast swaths of the California Coast have been taken over by it. It even likes the desert (Phoenix). Attached is a view from La Piedra State Beach, where we State Parks volunteers have been battling it or years.
