Plant Type: Vine

 

Solanum crispum ‘Glasnevin’ is a prolific and long blooming vine.

Garlands of vines make use of vertical space in the garden. Over pergolas, along fences, and arbors they add a great element of romance and luxuriance. We love unusual vines and focus on fragrant, cold hardy Jasmines. It is possible to have vines blooming year round in our climate. Take a look at the winter blooming Clematis- they are loved by overwintering Anna’s Hummingbirds. We have a good selection of the very best performing vines in our climate from evergreen to deciduous. And don’t forget the magic of perfume.

Trachelospermum j. ‘Pink Showers’ and jasminoides.

Hot Tip for Vines: You are not limited to where you can put a vine. Employ the use of #4 gauge copper wire. It may be coiled and hung on bare fences with the help of sturdy eye hooks. It can guide a vine around a post like a garland- and quickly send any vine soaring up a huge pergola.  This gauge wire is extremely strong and lasts for 20 years or more. In time the copper surface develops a nice green verde gris patina. #4 Copper wire can be purchased in bulk at big box home stores with an electrical section. It averages around $1.10/ft. But remember it lasts for 20+ years- a great investment.

Jasminum officinale ‘Old Portland’

Years ago when I lived in southeast Portland, not far from where our shop is located I noticed a huge, old Poet’s Jasmine that straddled a fence with an 1840’s Bungalow behind it. I’ve always been a big fan of Jasmine so it was in my pervue. Fast forward 20 years and  when we went to check out the lot for our shop that Jasmine was still there. Peeking over the fence. Since then it has become a prime feature in our border and with extra love and water its gotten huge. We’ve grown quite a few cultivars of Poet’s Jasmine and there is one prime difference that makes this an exceptional plant. Unlike most Jasminum officinale which are most fragrant in the evening to morning this selection pumps out perfume 24 hours a day. A hot day at the shop is a wave of sweet jasmine perfume. Vigorous, deciduous hardy vine with a huge flush of bloom beginning in June and extending to August with some spare flowers into autumn. To 15′ tall and spreading. This large twining vine requires space and a strong support. In time the trunk becomes a bare, gnarled corklike texture and is pretty in a rough way. Fall color is a little yellow to very little  Sublime with white fragrant stars raining down for months.Excellent in concert up a pergola with roses. Also, I later found out that our 1840’s bungalow neighbor was the first home owned by Asian Americans on the east side of the Willamette River. I have a strong suspicion that this venerable Jasmine could be VERY old. Classic starry white flowers and fragrance on a tough, long lived vine. Native to central to eastern Asia. Moderate deer resistance.

Lonicera ciliosa

PNW Orange Honeysuckle is one of our most showy native vines. Our region is sparse on native vines so this pretty plant is welcome. In late spring to summer clusters of brilliant orange tubular flowers decorate the branch tips. Loved by hummingbirds as well as other birds which is obvious, its also important for all native pollinators. The flowers change to brilliant red fruit which is consumed  by wildlife and seldom lingers.  Deciduous mid green foliage is verdant all through the season. As with the vast majority of Honeysuckle vines this plant nearly always goes leafless at the base. Expect this and plan for it. Strongly twining plant to 12′ tall and almost as wide. Provide strong support. Light consistent summer water to establish then very little necessary once established. (Also accepts regular summer H20). Excellent vine for country fences, decorating mailboxes etc. Protect from deer, otherwise it is pest and disease resistant- occasional mildew in the autumn is virtually harmless – great news for a honeysuckle. Blooms on wood from the previous season, prune if needed after flowering. This vine can be very hard to find. We grow it from seed and quantities are limited.  Oregon native plant

Lonicera hispidula

Hairy Honeysuckle or wild pink honeysuckle is a common vine in the western part of our state. Ranging rom S. British Columbia to California. This sprawling and twining plant is most associated with the cover under white oak woodlands. This vine can crawl to impressive heights into trees. As a child near Eugene this grew extensively on our property. It would climb pole sized trees and I would strip the winding canes off the trees and use them as a trellis for annual vines. The strong wood lasted 10 years or more. It derives its name from the conspicuous hairs on the leaves. At terminal ends of the branches soft pink curly flowers appear in cymes from June to September. These are followed by brilliant red berries that are food for birds. It has no fragrance. Excellent plant for stabilizing banks and hillsides where its incredible tenacity and drought tolerance is an advantage. Never a tidy plant this vine can be sent up a trellis or large tree. Water to establish then set it free. This honeysuckle can be afflicted with aphids early in the season but I’ve never seen it actually inhibit the plant. Just make sure not to look to closely at the plant in May-June. Evergreen to semi-evergreen with round leaves that surrounding the stem nearest the ends just before the flowers appear. Best in wild areas.- for some it can lack the sophistication of our other native honeysuckle Lonicera ciliosa. and is not as immediately beautiful. In habitat it consorts with Oregon White Oak (Quercus garryana) Poison Oak (Toxicodendron diversifolia) and Creeping snowberry (Symphoricarpos albus). Often found clambering up steep rocky slopes in dry woods. Oregon native plant.

Lonicera x americana

A hybrid between two European species has yielded one of the best climbing honeysuckles we can grow. Less prone to pests and disease this prolific blooming vine produces huge trusses of pink/yellow/cream highly fragrant flowers from late spring to autumn. A non-twining semi-evergreen vine that requires the support of something in which the canes can interweave and be supported. Often bare at the base- plan for this. To 12′ tall and as wide. Massive initial display of flowers in late spring and then sporadically until Sept. Full sun to light shade and regular summer water to increase vigor, spur re-bloom. The fragrance is not sweet and cloying rather a complex blend of cloves, cologne and petunia. It carries for quite a distance. A good sized specimen will perfume the entire block.

Mandevilla laxa

Chilean Jasmine is not common in our region but it has been grown for many decades and it does well in warmer gardens, protected places. Large entire deep green leaves are 3″ long and  opposite on twining stems. This strongly growing vine requires heavy and reliable support (See #4 copper wire). Blooms on new growth, which is continuous, In rich soil it can achieve 15′ in a season. The 2″ long tubular white flowers have the familiar propeller petal configuration of this family the Apocynaceae . The fragrance to me is delicious on warm days and nights and close to the blossoms which appear in clusters. It is not a sweetly cloying scent but more sophisticated. I once had this vine around my front door. In full bloom on warm summer nights it would be a cloud of perfume. Deciduous and often freezes back either 1/2- 3/4 of the way in colder than normal winters. In horrendous winters (below 12ºF) it can freeze away. Choose a protected site in full sun with rich soil and ample water. The more verdant the growth the more profuse the display and fragrance. Blooms late May- October. Avoid, cold frosty sites, cold gardens. In rural areas place it against  south facing wall. Because it blooms on new wood and grows so prolifically it may be cut nearly to the ground for a fresh start to the year- do this in late March.  In most summers large two chamber connected bean pods are 8″ long and bright green. When they ripen to tan they will twist and release downy clad black seeds that sail on the wind. Several winters in a row and the seeds that germinate may survive. I almost always lose them but the climate is changing and don’t bet on self sowing any way -its rare  Root hardy to about 5ºF- mulch for added protection. Exquisite vine. Native to central southern Chile.

Passaflora caerulea ‘Becky’s Blue & White’

Blue crown passion vine is an incredibly popular if huge vine in our climate. This form has the typical 3″ intricate flowers with the tinker toy center but the filaments that encircle the middle are deeper blue w/ a contrasting zone of brighter white. The result is bolder coloration and contrast. Rampant evergreen vine to about 13ºF . The vine is root hardy to about 0ºF- especially when established.  Give this big vine room and proper support. To 18′ tall and wide very quickly in average, well drained soil. Evergreen lobed leaves are glossy and this vine blooms profusely on new growth. The more it grows the more it blooms. Winding tendrils assist its climb and will adhere to anything with a diameter smaller than a regular sharpie pen. This includes screen…and if it is too close to a house and they attach to the screen….bad scene getting them off. Otherwise provide a trellis or pergola that can accommodate its size. Flowers appear from May-Frost. It may be cut back very hard in spring to refresh, supply new blooming wood, or just to restrain. Overly rich soil leads to rampant growth and less flowering. So, average soil that drains is ideal. Flowers often transform into golf ball sized orbs that are sweet tasting but not really food. Established passion vines will often sucker quite a way from the parent plant. Plant for this and be vigilant. There is no vine, however so magical in flower form that it transfixes people and is a special joy for children. Little water once established. Deer resistant. Mountains of Brazil.

Passaflora caerulea ‘Snow Queen’

Ravishing pure white intricate flowers flow from this passion vine, which can be rambunctious in the wrong place. Large growing plant to 20′ (long) tall and attaching itself  firmly by tendrils. Full sun in average soil with a lot of water to establish. Once established it is on its own. Too much irrigation and soil that is too rich leads to prodigious growth that can get rank and lack bloom. So, don’t starve it, just put it in reasonably good soil, that you have double dug. Water faithfully to spur growth. Semi-deciduous to evergreen in our climate.In winters below 15ºF and depending on the length of cold it can be totally deciduous. Good performance on the Oregon coast.  5″ wide flowers have a light sweet fragrance. Moderate deer resistance- it can also climb out of reach. Wonderful white passion vine.
