Obscure but exceedingly handsome and reliable shrub for hedges, specimens, eventually a small tree. Rounded leaves are good looking year round and especially when they first emerge brilliant salmon red before settling to dark green. This is the most showy display on this plant and it lasts for weeks. In mid-late summer small pendant white/cream flowers are nestled among the leaves, you really have to look to see them. Clean evergreen whose foliage is never marred by fungus or cold. Full sun to high overhead shade. To 8′-10′ tall and about half as wide. With great age and no pruning it can achieve small tree status and it forms attractive cloud like crowns of foliage. As a hedge it excels. Plant 2 gallon plants on 3′ centers and mulch. Irrigate about once a week until you see good new growth. Established plants are very tolerant of dry conditions. Theaceae- Camellia family. Excellent cold hardiness to 0ºF, tolerates some subfreezing wind. Excellent companion plant for Rhododendrons, Pieris, Illicium. Full sun to quite a bit of shade. Native to Japan. Good looking tough plant. Light deer resistance.
Foliage Color: Dark Green
A fantastic, tough and exotic looking evergreen (conifer) that is striking and easy to grow. To 4′ in 10 years, a slow growing shrub that is often as wide as it is tall. The scale leaves are deep glossy green liberally splashed with cream. The large leaflets protrude from a single trunk and is layered like a gigantic moss. The foliage is glossy on the surface and dull beneath. Wonderful specimen or even small hedge. Scaled very well for large rock gardens. This is a very rare form of this enchanting species native to Asia. Full sun and water to establish, let it dry between irrigating, then in a year or two it can survive on natural rainfall alone. Very cold hardy and takes the subfreezing wind from the east with no damage. Excellent in the Columbia River Gorge. Not bothered by deer,and likely not bothered by rabbits, but we are not 100% sure, but its worth a try. Good appearance year round.
Elk Horn Cedar is originally from Japan but is grown around the globe This layered and refreshing glossy green conifer grows very slowly and looks fantastic year round. Slow growing to 3′ x 3′ in 10 years. Excellent in mixed borders or shrub borders. Water well to establish the first summer then occasional deep soaks in summer. Unlike any other confier the name elk horn refers to the flat leaflets that look to me like a form of giant moss. Works well in winter containers. The flattened scales are glossy on the surface and dull beneath. This is the darker green of two varieties in the nursery trade. It would make a challenging bonsai. Full sun to light shade in rich to average soil . Not often deer food, very worth trying. Cold hardy below 0ºF for short periods. Excellent performance in the Columbia Gorge.

Tolmiea menziesii
Piggy Back plant is what we called this moisture loving woodland plant. Its famous for its ability to sprout a new plant right from the leaf petiole, it forms roots and drops off the plant and roots into the ground. Its also commonly known as a very easy to grow houseplant. Native from Southern Alaska to Northern California. In moist, cool climates like the coast it can grow just about anywhere. The distinctly arrow shaped leaves cover the ground densely on a wide spreading perennial. In mid-spring 2′ spikes erupt with rows of brownish-red flowers. A member of the Saxafrage family and closely related to Heucheras and Tiarellas. this is as superb a garden plant. Evergreen and consistently moist shady sites are where it thrives. Though with some supplemental water it can make its home in some pretty challenging dry shade. Foliage forms spreading mounds to 10″ tall and spreads laterally 2′-3′ when happy. Plants shrink somewhat in winter, and not as verdant but they do cover the ground and out compete weeds. Great container plant. Very nice naturalized among ferns of any kind.

Trachelium caeruleum ‘Dark Purple’
Florists variety of Flossflower that we think makes a nifty garden plant too. Large rich violet umbels repeat through summer. Remove spent flowers to encourage more.

Short lived perennial- approximately 3-4 years per plant. Freezes to the ground below 20ºF- resprouts from the base if temperatures never drop below about 10ºF. Often self sows in open disturbed sites- even following hellacious winters that compromise the parent plant. Best in rich, soil that drains, double dig the soil to incorporate oxygen into the root zone and allow water to penetrate deeply. Light summer water- extends bloom. If you cut the main bloom on each stem- and it will last for 10+ days in a vase, the sides of the plant will erupt in further bloom and continue to autumn. Loved by butterflies who find an accommodating landing pad and copious amounts of nectar filled flowers. Iberian peninsula and Mediterranean.
Trachelospermum asiaticum ‘Fragrant Form’
About 30 years ago I was introduced to this form of Asian Star Jasmine in Eugene. It was passed around as a clone that survived the disastrous freezes of 1989 and 1990. Its also sweetly fragrant where most varieties of Asian Star Jasmine are not or faint. This is an actual pleasant aroma, not as heady as the more common Star Jasmine Trachelospermum jasminoides, but pleasantly sweet. The parchment colored flowers appear for an extended period from June to September. A huge flush of flowers in early summer and then sporadically for months. Rich to average soil with regular summer water to establish and speed growth. Asian Star Jasmine waits to grow until truly warm weather is consistent. Regular water + warmth leads to a spreading ground cover or in wind free places it can self attach to surfaces and climb. To 12′ tall as a vine 18″ tall x 3′ as a ground cover. Full sun to considerable shade but not competition from tree roots. Very cold hardy form tolerating temperatures below 5ºF for short periods. Glossy undulate leaves are handsome year round. Wonderful, durable, ground cover. Establish this plant well before its first winter and mulch for added protection. One of our favorite forms of Asian Star Jasmine. This performs just as consistently as other clones that have proved their durability. Not bothered by deer. Tolerates dry shade when very well established. Both as a ground cover and as a vine it clothes itself densely in foliage never any bare knees. Roots along the ground as it goes, great on slopes.
Xera Plants Introduction
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.
