What I can't grow and have tried to grow numerous times are perennial Oriental poppies. I love those things and if I plant them in the fall they will grow just fine in fall, winter, and spring. Then the summer kills them and they don't return. I keep thinking that someday I'll find the perfect spot combined with a plant that has a bit of heat resistance and have success, but I think I'm probably wasting my effort when I do it. My last time was to attempt them in a container thinking I could guarantee perfect drainage and move them into the shade where it's cooler during the summer. Didn't work.
