Which one's Olga?

Here is my three sisters bed. I've grown sweetcorn and runner beans in two humps about 2ft across each, with squash planted between the humps - a variation of the traditional Iroquois women's planting scheme called the three sisters. Proper feminist allotmenteering! Apparently the beans nurture the nutrient-hungry sweetcorn, while the squash provide a mulch to keep water in and weeds out with their big spreading leaves.
