Not Just Any Green Beans... African Green Beans!

Last year my garden miraculously grew green beans that I didn't plant. They were really long. This year they miraculously re-seeded themselves, and they are still really long (one bean can completely wrap around my head... not as pretty as a beaded Zulu headband, but it was the best I could do...). This one was 22.25 inches (56.5 cm) long (and now you know how big - or small - my head is!)
