In the vegetable patch, pole bean seedlings send up new, green tendrils–slightly streaked with purple–that wrap around the bamboo “teepee”. Sweetpeas begin to stretch their threads out and up as though seeking support; they’ll even twine around grass stems. With all this rain, tomato plants surge and leaf out.
Among the perennials, weedy vines snake and coil: poison ivy, virginia creeper, bindweed, creeping charlie, nightshade, wintercreeper, wild cucumber. These plants make the process of keeping my perennial beds “clean” very challenging.
But the clematis vines, which I love, also use tendrils to spread themselves over bushes and trellises.
In botany, the curl or tendril is termed cirrus. Visualize the cirrus cloud, thin and thready and curled:
It’s easy to imagine how the apparent action of tendrils inspired metaphor and why humans so easily anthropomorphize the twining and vining as grasping, embracing, tugging, clinging, clasping–terms that are by turns tender and aggressive in implication. The plant’s tendril is, in fact, sensitive, another word that can be used to describe people but which means, in botany, something closer to irritable (susceptible and responsive to touch). The Encyclopedia Britannica says:
Tendrils are prehensile and sensitive to contact. When stroked lightly on its lower side, the tendril will, in a minute or two, curve toward that side. As it brushes against an object, it turns toward it and—the shape of the object permitting—wraps about it, clinging for as long as the stimulation persists. Later, strong mechanical tissue (sclerenchyma) develops in the tendrils, thus rendering them strong enough to support the weight of the plant.
Usually, that means a movement upwards–toward light, against gravity–another metaphor we human beings like to adopt.
Because these are things all human beings need: support, and a way to move toward the light. A little sensitivity helps. Then, strength can develop; we can bloom.
