Vines in the wild are downright exploitative. They do not support their own weight, so instead climb or sprawl over shrubbery and trees. Some are satisfied staying down below the canopy of the hosts who support them, as if aware that a healthy host will support them for a good long time. Many vines climb aggressively to the top and overwhelm their hosts, even if it eventually kills them.
There is nothing civil about the technique of the strangler figs, which incidentally includes two popular houseplants, fiddle-leaf fig (Ficus lyrata) and creeping fig (Ficus pumila). They wrap their hosts in networks of stems and roots that strangle the hosts as both the hosts and the clinging vines grow and expand. As the host’s die and rot, the vines develop into self-supporting tree trunks.
That is how fiddle-leaf fig, as it is known as a houseplant, grows as a freestanding tree rather than as a creeping vine. It is grown from cuttings from the self-supporting adult growth rather than the creeping juvenile growth. Conversely, creeping fig is grown from juvenile vines, which find a support to cling to, and ultimately develop shrubby adult growth when they get to the top of the support.
English and Algerian ivies are not quite as aggressive, since they do not intend to kill their hosts. They are not often intentionally grown as vines, and are almost never planted anymore, but their juvenile growth still works as ground cover in many mature landscapes. One of the main problems with ivy is that it is constantly trying to climb walls and trees so that it can bloom and toss seed.
That is not such a problem on concrete walls, but ruins wooden and painted surfaces, and makes a mess of trees.
Boston ivy (which is not really an ivy) lacks a juvenile ‘ground cover’ phase, but if kept off of painted and wooden surfaces, happens to work better on concrete infrastructures. It is important to know how a particular vine will behave before selecting it for a particular application. Carolina Jessamine, Mandeville, lilac vine and star jasmine are a few complaisant vines.
Highlight: Star Jasmine
There is some debate about the origin of the common name of Confederate jasmine. Some attribute it to its popularity in the former Confederate States of America. Others believe it originated in the Malay Confederacy, much closer to its native range. That is irrelevant here, where we know this popular vine with very fragrant flowers simply as star jasmine, Trachelospermum jasminoides.
One might think that it is too common, but there are reasons for that.
The dark green foliage is so delightfully glossy all year. As appealing as it is alone, it is even better as a contrasting backdrop for the small but strikingly white star shaped flowers that bloom in profusion about now, and continue to bloom sporadically for much of the rest of the year. The lavish fragrance is totally awesome!
The twining vines climb luxuriantly to about the height of first floor eaves. They can climb much higher, but higher growth takes a while to get as billowy as lower growth. However, it is more often grown as a shrubby ground cover, only about two feet deep. The simple leaves are two to three inches long, and one to one and a half inches wide. The clustered flowers are about an inch wide.
