I continue to be intrigued by the many twists and turns of the tendrils of muscadine grapevine (Vitis rotundifolia). The more attention I pay to them, the more I begin to wonder at patterns I notice. For example, it seems as if all the bright red tendrils are located near the top of the vine, in places exposed to direct sunlight. The tendrils lower down on the plan tend toward much paler red or even green. I wonder if the red tendrils contain a photosynthetic pigment that the green ones do not. Something to research further….
