I have tried for more than 16 years to grow hostas in the ground at our house. No matter where I plant them they falter and slowly die over 2 or 3 seasons.
Several years ago my dear friend Becky gave me a saucer-shaped pot full of young hostas. They are the only ones I have not been able to kill. If you look closely you can see the saucer these plants live in, but it's pretty tough since they are so happy they overflow it.
