My parents have a home in Florida and my Dad often complained about a shrub near the front of the house that visitors saw every time they came to visit. For some reason nothing would grow there and it had been replaced several times. Then he got a stone, a black stone. He was so proud of that stone. He would tell us how it never needed to be pruned or fertilized. It made it through the hottest parts of the summer, never wilting back. If there was a late spring frost warning, he never worried about it getting nipped by the frost. If someone hit it with their car door, well, they were more careful next time.
So become a rock-star and find a stone and set it in your garden. I guarantee it won’t be your last.
