All the stems of the morning glory plants growing on my balcony coil in the same direction. When I moved some of the plants, I recoiled them by hand onto the strings they creep around. Those that I had coiled in the 鈥渨rong鈥� direction started to coil in the 鈥渞ight鈥� direction as soon as they could. Why is this?
