Cup Of Gold Vine

‘Variegata’ is a bit less aggressive.

Trellises, arbors and pergolas for this vine should be strong. Cup of gold vine, Solandra maxima, can grow quite large, and it can do so quite fast. It easily reaches forty feet high and wide. Within ideal situations, vines can grow a hundred fifty feet long! Fortunately, it is conducive to frequent pruning. It can grow as free standing shrubbery without support.

Flowers of cup of gold vine compensate for their lack of abundance with size. Individual flowers may be six to eight inches long and three to six inches wide! Bloom is not overly profuse, though. It occurs mostly between January and May, with a few sporadic flowers during summer. Bloom begins pastel yellow and darkens to richer gold as it progresses.

The simple foliage is nicely glossy. Individual leaves are alternate and two to six inches long. ‘Variegata’ produces delightfully variegated foliage, and is relatively docile. Cup of gold vine needs shelter from frost though, so may not be suitable where winters are cool. It grows almost too easily from cuttings or layers. Stems might root where they touch the ground. All parts of it are toxic.

Trellises And Arbors Provide Support

Boston ivy climbs without a trellis.

Vines are very diverse. A few are annuals. A few are perennials. Many are woody vines. Some climb by twining their stems, leaves or tendrils. Some cling onto their support with aerial roots or suction discs. Within home gardens, some need the support of trellises or arbors. Most vines are naturally aggressive, so should get all the support that they need.

Vines that cling onto their supports with roots or suction discs need no trellises or arbors. They climb regardless. English ivy clings with aerial roots. Boston ivy clings with suction discs. Both can be destructive to their support. They ruin paint and promote rot in wood. Therefore, they should only climb surfaces that they can not damage, such as concrete.

Vines that climb by twining their stems, leaves or tendrils are the sorts that need support. On trellises, some can cover otherwise bare walls or fences, or stand freely like hedges. On arbors, vines frame gateways. On pergolas, they mostly shade patios like small trees. Vines are not low maintenance, though. Actually, they require specialized maintenance.

Vines, by nature, seek the top of their support, where they grow the most. Consequently, vines on trellises tend to get top heavy. Carolina jessamine, lilac vine and mandevilla all need grooming to limit upper growth. Then, their lower growth is fuller and more uniform. Star jasmine is naturally more uniform, but even it may get somewhat overgrown on top.

Upper overgrowth may not be so undesirable on arbors or pergolas. However, pruning is as important. Grapevines need annual dormant pruning during winter. Such pruning is a bit more complicated at the height of a pergola. Wisteria can be spectacular on pergolas. It needs aggressive pruning, though, so that it will not become too overgrown and heavy.

Bougainvillea is one of several vines that does not actively climb. It requires guidance to follow trellises or arbors, or to reach the top of pergolas. Then, it needs frequent pruning to avoid overgrowth. Its various cultivars behave differently, though. Some stay compact enough for small trellises and arbors. Some grow large enough for substantial pergolas.

Morning Glory

Morning glory can bloom until winter.

Popular garden varieties of morning glory are descendants of various species of Ipomea. Too many species are involved to classify such varieties briefly. Perennial morning glory, particularly the blue dawn flower, can be invasive. Most others perform as annuals, so do not grow long enough to be invasive. However, they can self sow to become numerous.

Although it might self sow and grow in any soil, morning glory prefers rich and loose soil. It also prefers regular irrigation, and will wilt if its soil gets too dry. Roots disperse deeply, so dislike pots. Morning glory in pots typically stays smaller than the same in the ground. Morning glory grows best from seed, which should go into its garden at the end of winter.

Some annual varieties of morning glory can climb ten feet high. Some grow only four feet high. They are delightful on picket fences. Their cordate or lobed leaves are about two or three inches wide. Their simple circular flowers are about the same width. They bloom in rich hues of blue, purple, red, pink and white. Some types have stripes, streaks or spots. Several exhibit central star patterns.

Grape

Grapevines are productive and visually appealing.

Grape, Vitis spp., has been in cultivation for approximately eight thousand years! That is a very long time for many diverse varieties to develop. Most are cultivars of Vitis vinifera, but other species and hybrids are in cultivation also. Grapes are useful for juice, vinegar, wine, jelly, fresh eating and dried as raisins. Each application utilizes particular cultivars.

Grapevines are very vigorous. Without pruning, some can climb more than fifty feet high. Within home gardens, specialized dormant pruning limits most to less than ten feet high. On larger vines, fruit is awkward to reach. Vines climb with tendrils, but are conducive to redirection on trellises, fences or arbors. They are deciduous, so are bare through winter.

Grapes grow in clusters of all sizes, from only a few grapes to two hundred or more. Fruit can be green, yellow, orange, red, pink, purple, dark blue or black. Table grapes are the most familiar seedless type for fresh eating. Wine grapes are smaller and contain seeds. Established vines do not need much water. Excessive irrigation can compromise flavor. Bare root vines become available for winter.

English Ivy

English Ivy often climbs into trees.

With containment, English ivy, Hedera helix, is a dense and evergreen groundcover. As it matures, it eventually excludes weeds. Containment is very important, though. It grows fast into trees and shrubbery, and clings to buildings. On buildings, it promotes decay of wood siding and ruins paint. As a vine, it is safe only on concrete and cinder block walls.

Juvenile growth of English ivy is mostly rather compact. Ideally, it is less than six inches deep. It gets a bit deeper where shaded. Leaves are as wide as three and a half inches. Stems develop roots where they touch the soil. Adult growth is shrubby, though, and can protrude several feet higher than its support. It blooms and produces small black berries.

‘Hahn’s’ is probably the most popular cultivar of English ivy because it branches so well. ‘Needlepoint’ has elegantly narrow foliar lobes. Cultivars with yellow or white variegation grow notably slower. They are popular as foliar components in big pots of mixed annuals and perennials. Some of the hundreds of cultivars are more popular as houseplants than outside.

Vines Are Naturally Very Competitive

Some vines climb with clinging roots.

Nature is competitive. Competition is natural. In the wild, vegetation competes for limited resources. Where sunlight is a limited resource within forest ecosystems, competition for it is fierce. Understory vegetation does what it can in the shade of taller trees. Taller trees strive to be the tallest for more sunlight. Vines are the most aggressive competitors of all.

Vines are blatantly exploitative. They rely on trees to do the work of growing to the top of the forest canopy. Then, they climb into and over such trees to grow even higher than the trees do. Some can overwhelm and even shade out and kill the trees that they rely on for support. Strangler fig literally strangles its hosts as it develops its own supportive trunks.

Vines climb with clinging roots, twining stems, tendrils, twining leaves or hooked thorns. Some are perennials or even annuals. Some sprawl over the ground while juvenile, and then climb as they encounter support. As they reach the top of their supports, such vines generate shrubbier adult growth. Then, such adult growth can bloom and generate seed.

English ivy, for example, is a practical groundcover plant in its juvenile form. However, it becomes a clinging vine when it finds support. It quite often climbs shrubbery, trees and buildings. If left unattended, it develops into shrubbier growth that blooms and produces seed. Such shrubby growth shades desirable vegetation, and on buildings, promotes rot.

Carolina jessamine, lilac vine, mandevilla and wisteria climb by twining stems. They are generally not as potentially destructive as clinging vines. However, they can crush lattice or small trellises. Wisteria can crush substantial trellises. Like English ivy, star jasmine is likely more popular as a ground cover. It performs double duty, though, as a twining vine.

Bougainvillea neither clings nor twines. It merely produces vigorously tall canes that flop over on top of their support. Long thorns help to anchor them into place. Therefore, such canes need a bit of help to climb trellises or other support. They must be tied in place or woven into their trellises. Various other vines exhibit various and distinct characteristics.

Blood Red Trumpet Vine

Blood red trumpet vine can get aggressive.

Abundant lush foliage is actually the main asset of blood-red trumpet vine, Distictis buccinatoria, with the sporadic clusters of three inch long tubular flowers blooming as an added benefit during warm weather. Bloom can certainly be impressive when least expected though; and has a sneaky way of getting a late blast of color out during Indian summer weather patterns, when the weather gets warm after a cool phase in autumn. Contrary to the name, the flowers are more ruddy orange with yellow throats than blood red. The rich green leaves are compound, with a pair of three inch long leaflets and a three fingered tendril reaching out from between.

The vines are somewhat aggressive and can climb more than twenty feet, so need adequate support. They should not be allowed to overwhelm smaller or slower plants, or escape out of reach into adjacent trees. The tendrils can grab onto and damage shingles and light fences, but are an advantage for covering chain link fences. Given the opportunity, blood-red trumpet vine can even climb rough cinder block or stucco walls.

 Passion Vine

Passion vine has the weirdest flowers.

My niece knows the weird flowers of passion vine as ‘flying saucers’ because they look like something from another planet. The most common species, Passiflora X alatocaerulea, has fragrant, four inch wide flowers with slightly pinkish or lavender shaded white outer petals (and sepals) around deep blue or purple halos that surround the alien looking central flower parts. The three inch long leaves have three blunt lobes, and can sometimes be rather yellowish. The rampant vines can climb more than twenty feet, and become shabby and invasive, but may die to the ground when winter gets cold. Other specie have different flower colors. Some produce interesting fruit. Passiflora edule is actually grown more for its small but richly sweet fruit than for flowers.

Star Jasmine

This jasmine is quite a star.

It is certainly a star within many gardens, but it is technically not a jasmine. Star jasmine, Trachelospermum jasminoides, is actually closely related to Plumeria. Its floral fragrance can be comparably rich with copious bloom, but is distinctly vanillish. Bloom is abundant for late spring and early summer. Sporadic bloom can start early and continue to autumn.

Without bloom, the distinctly glossy foliage is handsome alone. Individual leaves are not much longer than two inches, and not much wider than one. Their deep green foliar color and lustrous sheen almost seem artificial. Pruning or any disturbance of foliage or stems releases caustic and toxic sap. Twining vines ascend by wrapping around their supports.

Star jasmine can get two feet deep as a ground cover without support. It requires pruning to prevent it from overwhelming shrubbery or climbing into trees. It also requires frequent pruning around its edges. As a climbing vine, it grows fast to ten feet high, and can grow much higher a bit slower. It can become a neatly shorn faux hedge on a chain link fence.
