Spring bouquet viburnum or Laurusitinus is a common shrub in our climate. This form lightens up what can be a very pedestrian plant. The edges of the evergreen leaves are margined in cream with an interior of soft green. This makes a shrub that glows year round and can be used to lighten up dark corners. In autumn clusters of pink buds form and hold until mid winter. Then as the days begin to lengthen it opens these clusters which are lightly fragrant and white. Strong growing shrub that requires very little water once established. To 8′ tall and 5′ wide in 6 years. Full sun to part shade to high overhead shade. Nice looking, tough shrub native to the Mediterranean very easy to grow and long lived. If a green sport appears simply prune it off to the base to retain the variegated form. Water to establish. Not deer resistant. Excellent backdrop to a mixed border or trimmed into a contained hedge. Nice fast growing screen. Blue berries sometimes follow the flowers. Buds and flowers put on a show for months. Blooms on wood from the previous season prune after flowering if needed. Naturally dense and rounded.
This is a remarkable oak whose geographic center is in high elevation Mexico. There are several forms of this evergreen tree with remarkable qualities. Its range extends from the SW U.S. south throughout Mexico into northern Guatemala. This southwest form has shown great cold hardiness and adaptability. These are started from acorns in a garden in Medford. The parent tree was pole straight with a boisterous green rounded crown. It is remarkably tolerant of drought and is cold hardy reliably to 0ºF. Full sun in average soil for a moderately fast growing tree. The outline of its crown is oblong at first and if you remove the lower limbs it will send the crown skyward. As I said the trunk was pole straight on a tree that was 35′ tall (18′ wide) and very pretty. Doing research on this tree it was found in California that this tree literally collects pollutants from the sky with its rough leaves. Its proposed to be planted along intersections and freeways and could be a boon to lower the particulate count. Dark green foliage looks good year round. Water to establish and then none in subsequent years. Grows fast for an oak and it really adores our climate. The bark is rough with gray striations. It makes many acorns and this should be taken into account in siting. Good candidate for a street tree or a garden shade tree. Average soil, including clay soils. Full sun from every direction for the straightest tree. Syn. Quercus reticulata. This would also be a good candidate for a formal large screen. Sometimes called net leaf oak or southwestern net leaf oak. Casts moderately dense shade with time.
Compact hybrid Corokia that has larger leaves that turn from gray to bronze in cold weather. To 4′ x 3′ in 6 years. The upper parts of the stems are more like soft gray rushes before the foliage elongates. In late spring starry bright yellow flowers spangle the older growth. Occasionally its followed by orange berries. Very forgiving shrub that we have actually grown for years. It has good cold hardiness for a Corokia x virgata hybrid and its compact, dense and good looking year round. Avoid the coldest sites, gains cold hardiness with age, protect the smallest plants from temperatures below 20ºF, after several years it will be hardy to the upper single digits. Makes a great sheared hedge and its used for that purpose in its home New Zealand. Great performance at the Oregon coast. Very good in containers. especially winter containers. This shrub has a much more burgundy hue in winter as opposed to the all gray look of Corokia cotoneaster. Easy to grow. This shrub would be good to try where deer are profuse. Its excels in containers in the urban scape of down town.
This is a different form of our locally native Buckbrush. We found this at approximately 2200′ on Mary’s Peak in the Coast Range in a forest that was comprised primarily of Douglas Fir and Golden Chinquapin. This shorter shrub with smaller deep green leaves is most conspicuous in its slick gray stems. To 3′ tall by 4′ wide in 5 years. Full sun and average to poor soil. Blooms April to May with ivory colored panicles that cover the whole plant on old wood. The sweetly fragrant flowers are always buzzing with pollinators. A true low water shrub that can easily get by on only what falls from the sky, once established. This is a cold hardy and locally native evergreen shrub. Often it grows in an arching and then angular kind of way. This form is less upright. Red seedheads follow the flowers. This is a very well known and stable population in the wild that is regenerating nicely. Extraordinarily tolerant of heat and drought. Oregon native plant.
Oregon cut leaf gold thread is a widespread but not common evergreen perennial that is found in dry shade on the west side the Cascades. Native primarily to Oregon it extends north into Washington and is rare south into California. A colony creating perennial that has handsome, intricate deep green foliage. The arrow shaped leaves are arranged in rosettes along the expanding yellow stolons. The effect is a dense cover that expands at a slow rate. In spring sparse thread like flowers are curious followed by swollen seed pods arranged in a circle. Rich to average soil in shade to dappled shade, though if pushed it can tolerate a little sun. Good year round appearance. It may be cut back at the end of winter, but I haven’t really found this to be necessary. Use its best attributes, adaptation to dry shade and evergreen good looks as a limited groundcover beneath woodland perennials or at its best on the forest floor. Not a wide scale groundcover and clumps expand at a slow/moderate pace. Not adapted to compacted or clay soils. Best in heavy duff on the forest floor. Great in shade containers at the foot of Aspidistra . Not bothered by deer. Limited quantities. It derives its common name from the bright yellow roots and stolons. Water until you see good new growth then set it free. Oregon native plant.
Wonderful dense, arching and low growing conifer for full sun and only occasional water when established. This cold hardy conifer is native to the highest elevations of Tasmania up into eastern Australia. In the summer the fine but substantial needles turn to dusty blue. The arrival of colder weather brings a distinct and beautiful soft purple cast. To 2′ tall and arching to 5′ tall in 7 years. Long lived and carefree conifer for full sun to very light shade. Dense and blocks weeds. Excellent large scale, weed supressing low water shrub. This cultivar originated in New Zealand and was released as a cultivar in 1994. Very good deer and rabbit resistance. Excellent appearance year round. It has been hardy slightly below 0ºF. Easy to grow.
Mudgee Wattle or simply showy wattle this is an extremely pretty small tree that requires a very protected location to thrive. Blue/green bipinnate leaves are intricate and pretty. In very late winter to early spring a stunning show of electric yellow puff ball flowers. It covers the whole tree weighing down the limbs in full bloom. To 12′-15′ tall in rich to average soil and it absolutely requires full sun. Excellent against a south facing wall. The flowers truly are showy and glow from quite a distance. Native to New South Wales and southern Queensland on table lands. Cold hardy to at least 18ºF- it should take colder temperatures if sited correctly. As with all Acacias it is extremely fast growing when young. Consistent summer water. Loved by hummingbirds and insects in general. This special small tree can begin its life in a spindly way. Full sun and regular water strengthens this growth. Excellent, and best adapted for the Oregon coast. It adapts to life on sand (with supplemental water) as well as well developed soils. Not bothered by deer. The large delicate leaves are blue/gray and are pretty year round. This Acacia is not as cold hardy as Acacia covenyi and is hardier than Acacia pravissima. Following bloom long dusty purple seed pods contrast against the blue/gray foliate. Bark is black to dark brown. Inland it is considered experimental. Eastern Australia.
Stellar passion vine with distinctly purple tepals and deep black to blue on the interior of the flower. Vigorous vine for a protected location in full sun. To 12′ in a season and blooming continuously from June to October. Attaches itself by winding tendrils. The flowers appear on new wood, as the vine grows it produces new flowers. Average to rich soil with REGULAR irrigation during the first season and then occasionally. Passafloras must be well established going into their first winter. In half of the winters (below 20ºF) it can freeze to the ground. It will then rapidly break from the base when truly warm weather arrives. Mulch heavily the first winter, Place on a trellis against warm, sunny wall for the best performance. The intricate and beautiful flowers are about 4″ across. Sometimes sets inedible fruit. Passion vines are loved by everybody but especially children. The toy-like flowers enchant everybody. Sweetly fragrant flowers up close. Loved by hummingbirds. One of the best hybrid Pnassafloras for our gardens. Moderate deer resistance
A very mysterious Gardenia that I got from the east coast and whose flowers are ENORMOUS and powerfully fragrant. Everything about this hardy Gardenia is big. The leaves are 5″x 3″ and are forest green and delightfully glossy. A moderately fast growing evergreen shrub to 6′ x 6′. Full sun but best in dappled shade in a protected location. Regular, consistent water is crucial. Gardenias like heat and water. Poorly irrigated plants will show yellow leaves on the interior of the plant before wilting. This is especially important since we’ve had consecutive dry springs and most likely you will need to water this plant beginning in April. Rich soil with regular water. Protect from subfreezing wind, and plant in rich soil with ample compost. Apply a handful of all organic fertilizer in early summer. The enormous flowers begin i July and continue to October. The only information I can find on this cold hardy cultivar is that it is particularly resistant to pests. Since Gardenias in our climate aren’t really pest magnets this is moot, but good to know. Spectacular flowers are 5″ across and semi-double. Excellent for corsages and even for floating in a bowl, one flower will perfume a wide area. It is crucially important that this shrub be well established going into winter otherwise its hardiness to cold will be compromised. Limited quantities.
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.
