I recently put yard fabric/pea gravel around the foundation in front of a new "pool deck". The PO had a moon plant there, but I got all the roots out. But its come back again! Not just one, but 4-5 by now. I like them, but as the summer goes on the blooms wilt and brown. Does anyone have experience growing them? I guess there a vine plant. I was thinking of saving some seeds and making a moon plant bed somewhere else.
