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.

Iris tenax

Oregon iris or Tough leaved iris is the most northerly species of Pacifica Iris- extending its native zone as far as SW Washington. Its common throughout the western part of our state where it decorates grassy hillsides in full sun to quite a bit of shade with jolly purple flowers April-June. That was the most common color where I grew up SW of Eugene. Turns out this Iris comes in quite a few colors. Pink, blue, white, golden yellow, red- all hues that have been recorded for this species. Conspicuous also, among the 11 Pacifica species this is a winter deciduous perennial and its the hardiest of the lot. Forms grassy clumps in fan shaped displays to about 10″ tall.  A large clump can be 30″ across and filled with nearly 100 flowers- these rise on cantilevered stems to 14″ tall. Not very tolerant of disturbance and to be honest it has stymied us quite a few times. They HATE division. Therefore, we feature seed grown plants- local seed. These plants feature extra vigor and usually bloom with in 3 years. They also establish better.  Best in light shade, dappled shade on slopes. Average, clay soil is what it wants and you can increase vigor by double digging the hole very wide to incorporate oxygen in the soil and water lightly and consistently through the first summer. Then none to light in subsequent years. And admirable competitor with introduced invasives and as per all Iris it is supremely deer and even rabbit resistant.  Winter deciduous- also, it may go drought deciduous in extremely dry summers. Mixes well with native annuals. Established clumps live for decades. The flowers have the light fragrance of root beer (at least to me) and are the only fragrant Pacifica species that I can detect.  First nation people used the incredibly tough leaves to braid into ropes, traps. Which is cool.  Photo credit: East Multnomah Conservation District. Oregon native plant.

This tree is wonderful in many ways. Its staunchly evergreen, but rather than the somber glossy leaves of Magnolia grandiflora these simple leaves are  grass green and matte. Moderately fast growing shrub/tree, on average 1′ to 2′ per year if sited correctly In mid April to mid May the most exquisite miniature magnolia flowers erupt directly from the stems. These adorable ivory pinwheels have a sweet sophisticated fragrance. Well behaved plant that is moderately dense and always healthy looking. Best in a protected courtyard or agains a west facing wall, do not expose it directly to arctic east winds.  To 14′ tall by 6′ wide in 10 years. Full sun but not reflected heat and adaptable to the dappled light of woodlands. In our experience it was unharmed at a brief dip to 7ºF.. This would make a fantastic and adorable espalier subject. The way the perfect flowers are arranged on the stem would lend itself well to that method. Rich to average soil, including heavy clay soils, Best with intermittent deep irrigation in summer. A deep soak once every two weeks on established plants. This rare smaller evergreen Magnolia deserves wider use in our climate.

Toothed leaved Azara is a somewhat obscure evergreen tree native to South America. Closely related to the more common Azara microphylla, this species has much larger leaves and MUCH larger gold flowers.  The puff ball gold flowers deck all the boughs in an opulent spring display that lasts for weeks. An upright broad spreading evergreen whose crown usually assumes a conical outline. Spreading branches hold the foliage which is very substantial. To 18′ tall and half as wide in 10 years. Best in a protected location, out of east wind, on the edge of a woodland or near a house. The large flowers truly are a spectacle and emit a light sweet fragrance. Full sun to high overstory shade in rich soil with occasional deep soaks in summer. Grows 1′-3′ per year and faster with attention to water. More tender as a youngster gaining full cold hardiness with age. Established trees endure 5ºF by losing many leaves- they can also disappear in particularly enthusiastic bloom seasons but it regains foliage very fast by early spring. Excellent performance at the Oregon Coast. Very elegant tree. Chile/Argentina.

Matthoila fruticulosa

Stock, the common early spring cut flower with that is wonderfully fragrant of cloves. The sweet perfume can be detected at quite a distance. This is a cold hardy, PERENNIAL version of that beloved flower. Forming a semi-woody dome like shrub multiple spikes to 10″ long eminate from the crown and bear pristine cleanly white flowers with that dazzling perfume. Great fragrant filler in bouquets. Native to mountainous areas around the mediterranean. To 2′ x 2′ and becoming a multi branched shrublet. Full sun and rich to average soil with light consistent summer water for the first season. Good drainage is important and its a natural plant for a slope. Established plants can get through summer without irrigation. The long strappy leaves are gray/green and add to the overall appeal especially when decked with white flowers. Average life span 5-7 years. Do not coddle. Combines well with Cistus, Halimiums, Helianthemums. Dianthus where it will compete for perfume. Very reminiscent of a Wallflower (Cheiranthus) and accepts the same cultural requirements. Blooms May-August. Pronounced muh-TOY-luh

Most Ceanothus are famous for their intense blue and profuse flowers, this interesting shrub has the typical masses of sky blue flowers which obscures the tiny warty foliage. To 5′ x 8′ and spreading wider than tall it becomes a cloud of blue in April and pollinators take notice.  Rolling in bees and every other awake pollinator a shrub in full bloom is a buzzing fountain of activity. Fast growing, wiry, dense shrub with extraordinarily dark green tiny leaves. This gives the shrub the distinct appearance of a cloud. Full sun  and average to poor soil including heavy clay soils that dry in summer. No summer water once established. Remarkably drought adapted west coast native shrub. Very easy to grow large, showy, shrub for wild areas, blasting hot urban hell scapes. Not totally deer resistant but better than most other species. Excellent performance at the Oregon coast. Endures sandy substrates and even a bit of salt wind. Attracts some of the first butterflies to emerge. Cold hardy to slightly below 10ºF for brief periods. Recovers from cold damage completely by bloom time.

Gilia capitata ssp pacifica

We once grew this form of Gilia capitata as our own local species. WRONG. We compared it to the southern Oregon Coastal variety ssp. Pacifica. That form is shorter but blooms are a distinctly darker blue. Everything as for the species Reseeds faithfully in OPEN disturbed sites with little competition from invasive weeds/turf grasses. This thick, stout variety makes a wonderful cut flower. It also has the same attractive properties that make it one of the best native pollinator plants. To 18″ tall and forming patches that reliably re-sows each year.  See above care. WE love both forms of this Gilly Flower made famous by early European settlers. They’ve spread this wild flower around the globe where it has become naturalized in parts of New England into E. Canada. Not a bad weed but an example of something from here with adaptation to another climate.  Oregon native plant.

Extraordinary Higo Camellia that is wildly showy and fun to grow. Higo Camellias are a form where the stamens rather than being clustered together in the center are instead splayed out in the shape of a star against smaller flat petals.  They are surprisingly rare in the United States. Its a different look for a japonica and we love it.  Moderately fast growing handsome glossy evergreen shrub for full sun to shade. To 8′ x 5′ in 7 years. Regular summer water speeds growth and increases flower bud set. Mid-season bloomer with flowers opening from February on. Rich to average soil, definitely apply ample mulch when planting. Good looking shrub at all times- w/ a somewhat formal appearance until the blooms open. 4″ wide flowers have flat petals that are white striped and stippled in peppermint red. Takes low water conditions when established. Long lived.

A really interesting and wonderful vine that we grow as an annual but its a perennial in warmer climates and can be here too if you treat it right. Arrow shaped leaves have modified petioles that attach and hoists this climber to 8′ in a single season. A continuous supply of tubular (snapdragon shaped) purple blue flowers with a white throat. Loved by hummers this native of the driest parts of the mediterranean is adapted to being dry in the winter and wet in summer. If wet and saturated the whole vine is only hardy to about 26ºF. However, if the plant is kept dry in the winter it is hardy to MUCH colder. In a former garden I had it planted against the south facing side of my house under the eaves. It was bone dry in winter and to my shock it lived for 7 years with temperatures down to 10ºF. I offer this information as interesting but its a primo delicate vine with beautiful flowers that appear continuously all season which makes a lovely seasonal bower. Great on a tripod, or teutier in containers. Full sun to very light shade in rich, well drained soil. Excellent on spring blooming shrubs that are quiet in summer- its a fine textured plant that will never smother the host. Excellent plant.

Our friend garden designer plantswoman extraordinaire Magi Treece spotted this Camellia and observed it over time. I too had noticed it around town- always large and VERY old. Its most conspicuous trait is to produce simple single fluted ivory flowers from pink buds. Up close these 3″ wide flowers have a decadent sweet scent. Its appearance is most like the species Camellia cuspidata which is a very cold hardy species known for its fragrant white flowers. Blooms appear from December (Often as early as November) and open until the end of February. The elegant flowers are tough and it takes some serious weather to impede or even damage the flowers. Deep green leaves are long and thin and very glossy/handsome with a sharp tip. The entire plant is good looking at all times. Ancient varieties around town are upwards of 15′ tall and 3/4 as wide. I’d say it would be an 8′ x 8′ shrub in 10 years. Regular water speeds growth and assists in bud set for the following season, this is only important in summer. Excellent specimen or hedge. This is one tough and beautiful Camellia.  Dig a large hole to disturb the soil around the planting site and set the plant in the hole even with the soil horizon. Backfill, water and mulch. Magi queried Camellia Forest about this plant with no luck. I queried Nuccio’s and their best guess was that it was a form of C. cuspidata or a hybrid close with it. Either way its one of our most favorite Camellias and we have our sweet friend Magi to thank. This Camellia looks and acts very much like an evergreen Magnolia and it could be used as a smaller substitute. The flower fragrance on warm days is a bit like a Gardenia. Moderately fast growing.
