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 "wrong" direction started to coil in the "right" direction as soon as they could. Why is this? Some winding plants such as morning glory and wisteria wind counter-clockwise (CCW). Others, such as hops and honeysuckle, wind clockwise (CW). Supposedly, you should not force them to wind in the "wrong" direction or they will wither.rnAlthough it is said that hops wind CW to follow the sun, the actual direction of winding is determined by the plant's genes and the pull of gravity.
