Vines are characterized by fast growth and limited lateral growth (although there are notable exceptions). They can be deciduous or evergreen, monoecious or dioecious, ten feet or one hundred.
Vines are plants that do not support themselves but scramble or climb upon others. They are an evolutionary adaption that developed independently in numerous plant families.
For what purpose?
Why dedicate energy to growing upright with a sturdy and rigid stem/trunk when you can take advantage of other plants to do that work for you? The great lianas of the rain forest (think the long ropey vines in Tarzan) reach the sunlit canopy by piggy backing on giant forest trees.
How do vines accomplish this? How do they climb?
They have developed a number of different strategies, sometimes using more than one of these strategies at the same time, and sometimes modifying a prefered strategy depending on the available support structure.
These various strategies have fascinated people in many fields of study for a long time. The mechanics of twining and tendrils especially are complex and have been the focus of experimentation and entire books dating back to Darwin. His "On the Movements and Habits of Climbing Plants" was originally published in the Journal of the Linnean Society of London, 1865, 9: 1-118 and later published on its own as a separate monograph. More recently, in-depth scientific explorations like The Biology of Vines (ed. Putz and Mooney, Cambridge University Press, 1991) have appeared.
Scientists study just how twining vines twine, in which direction they spiral, what their angle of their spiraling is, and how large a center structure they can spiral around, among other things. They study how tendrils reach out searching for something to grab onto, moving around in mid-air until they come upon something of the right diameter to meet their needs for attachment. Time lapse videos of both of these mobile strategies are fascinating to watch and provide scientists with detailed information on these complicated processes.
☞ Support Structures
Because of vines' varying growth habits and attachment strategies, it is crucial to provide the right kind of support for each particular vine. Do you need a wall or large post for adhesive pads or adventitious roots? Wire for tendrils? Posts of varying dimensions for different twining vines?
Whatever vine you have or are considering purchasing, be sure you can give it what it needs to do what it does.
Conversely, if you have a certain structure, whether it be a trellis, a wall, or a post, and you want to grow a vine on it, be sure to select a vine with compatible support needs.
ATTACHMENT STRATEGIES INCLUDE:
Use their petioles (the small stalks at the base of leaves) to twine around objects in a manner similar to the tendril climbers.
or Holdfasts: at the ends of tendrilsLike root climbers, lianas that have adhesive tendrils adhere to the tree or surface that they are climbing. However, it is not the roots that are doing the climbing in this case, but modified tendrils that have small adhesive pads at the tips.
