When I was a kid playing baseball, we always had one fan who was the guy who lived just off the right field foul post. His house bordered the ball field and it seemed he always had time to come and enjoy the games with us, and this was well after his kids had played through little league. He had his garden between the ballfield and his house.
It always happened, one, two, three times a game someone would hit a foul ball and it would land in his garden. In those days we did not have many spare baseballs, so the right fielder and first baseman, and others, would look for the ball. The man would always yell to them "Yall, be careful in them weeds, thars a garden under there somewhere"
I'll never forget hearing him say that. And now I can say, "Thars a garden under them fliers somewhere" I must say I think the flowers have given some needed shade during our hot summer. For 53 out of 54 days we have been above 90, and it was 89 the one other day.
but butterflies and bees love polygonums and I let some grow in various parts of my garden as well. Birds come after the seeds later on, too. Unfortunately, Japanese beetles like the leaves and some of mine are looking like Swiss cheese!
