Variegated Asian Star Jasmine. Excellent evergreen ground cover with playful foliage that looks great year round. Lovely entire leaves are spaced and outlined in cream. Great contrast to the sage green leaf interior. Trailing ground cover (occasionally it can rise up to be a vine- in windfree locations with support) but mainly its value is a year round showy and consistent look. Mounding and trailing it will root into the ground when it feels like it. To 10″ tall and 3′ wide as a ground cover. To 10′ tall as a vine. Full sun to dense shade in rich, well drained soil. But it adapts to harsher sites if given regular water. Excellent under trees, shrubs. Dense enough to discourage weeds. Very cold and drought tolerant. Seldom blooms. Moderate deer resistance. This and all Trachelsospermum asiaticum have two distinct forms of foliage. Juvenile and adult. Juvenile foliage is associated with long trailing and vining material. In wind free, still locations it can rise up as vine and thats when it becomes adult. This plant ONLY BLOOMS ON ADULT foliage. So, that is one reason you seldom see flowers on Asian star jasmine. Over time adult foliage will appear on ground covers. Its less vining and more bushy. Again, until adult foliage forms there will be no flowers.
Plant Type: 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.
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.
Climate Adapted Plants for Gardeners in the PNW
Trachelospermum jasminoides
Not a true Jasmine at all but Star Jasmine is a classic summer blooming evergreen vine in our region. One of the most popular vines and rightly so with its clouds of ivory colored propeller shaped sweetly fragrant flowers for all of summer. Twining vine, provide support- easily guided with the help of #4 gauge copper wire. It has the enviable trait of clothing itself to the ground in evergreen foliage- seldom has bare knees. Full sun to quite a bit of shade, including dry shade. To 12′ tall and 4′ wide in 6 years. Cold hardy to the single digits when established. Can be slightly tender when vines are young- hence the myth that it is not hardy. Regular water in summer speeds growth measurably and should be applied for the first few years. Blooms on wood from the current season. Prune before or after blooming. In warmer climates this vine is only a spring bloomer. In our milder summers with cooler overnight lows in summer it spurs Star Jasmine to bloom for all of our summer. Lucky us. Moderate deer resistance. Drought adapted with age. See below- trained as a free standing hedge in Laurelhurst. Kind of cool.
Trachelospermum jasminoides ‘Madison’
Reputed to be a hardier form of Star Jasmine, we really haven’t witnessed that. It seems just as hardy as the commonly grown clone. But it has several important differences. The large deep green leaves are conspicuously convex and thick. In June to September it alights with tons of ivory colored sweetly fragrant pinwheel shaped flowers. These are slightly smaller but come in such fragrant abundance that it doesn’t seem to matter. Evergreen from the base to the top which is nice. No bare knees. Full sun to quite a bit of shade in rich, well drained soil. Summer water speeds both growth and early establishment. Then light regular summer water. Moderate deer resistance. Twining to 15′ provide support. Fences, pergolas.
Trachelospermum jasminoides ‘Pink Showers’
Exciting color variant of star jasmine. Soft pink propeller shaped flowers yield the same sweet perfume. Blooms June-August and prefers part shade and protection from hot sun. The intensity of pink in the flowers is more pronounced in cooler conditions. Strongly twining evergreen vine with deep green, glossy, undulate (wavy) leaves which are handsome year round. To 10′ tall and 4′ wide in 5 years. Good cold hardiness. Provide strong support. Water heavily after planting and for the first summer. This will speed both establishment and growth and lengthen the bloom season. If it never bloomed (and the flowers are beautiful and fragrant) it would be a top notch evergreen vine on those merits. Excellent recent introduction. See video below (img 6053). Just below the main picture. A really great vine.
Trachelospermum jasminoides ‘Variegatum’
Nice form of star jasmine with large sage green leaves edged in cream. New growth emerges a very pretty pink. From June to August a continuous supply of clusters of sweetly fragrant ivory flowers. To 12′ tall and twining. Provide sturdy support. A nice attribute of Star Jasmines is their habit of keeping their foliage densely to the ground- never any bare knees. Takes full sun to quite a bit of shade- and still blooms. Slightly more tender than the species it requires a protected location- against a wall is ideal. Regular summer water speeds growth and this intensifies the re-blooming. Evergreen. Moderate deer resistance.
Trachelospermum mandianum
The apricot hued flowers of this Star Jasmine species are not the only difference in this elegant evergreen vine. The fragrance is different too with much more of a balmy citrus scent. Vigorous twining vine for part shade. Provide sturdy support. Very cold hardy and permanent. To 14′ tall and 8′ wide on trellis. Possible to use it as a small scale ground cover. Tolerates full sun but with some leaf discoloration. Regular summer water in well drained soil. Occasionally at the end of the season this species will form twin bean seed pods which are showy as well. Blooms earlier than Star Jasmine and finishes later as well. Evergreen foliage is light yellow green- lighter than other species of Star Jasmine. Moderate deer resistance.
