BAH's grandpa was a little bit of a gardener. He had some fruit trees, and when the fruit started forming, he would put a radio in one of the trees, tuned to baseball games, and that would keep the birds from eating the fruit. He also grew a perennial type of spinach.
He always had a lot of perennial spinach. Since I love spinach, he would always share a bunch with us when we came over to visit. Since it was perennial, it came back every year, same spot, unlike other spinach. It also had very pointy leaves, unlike other spinach. And the leaves grew on little stocks, unlike other spinach. Also, it tasted like no other spinach I've ever had before or since.
Actually, I'm pretty sure he just cultivated some sort of weed and believed it to be spinach. But it's the thought that counts, right?
