Siskiyou Iris is native to the southwestern part of Oregon. Though its named after the mountain range it is more often a valley species. You see it sparsely under Oaks, Madrones, and especially Ponderosa and Jeffrey Pine woods. Never at high elevations it grows in a host of soil types but the common component is that they all dry thoroughly in summer. Do not irrigate past the Fourth of July when established OR water only to establish the first year and then set it free. Forms almost caulescent evergreen fans that are red at the base. These rise to about 14″ and are not profuse. The plants which we raise from seed are a range of pale ivory to yellow all with conspicuous darker markings on the falls. Blooms April to May. Full sun to part shade and best with some protection from afternoon sun. In habitat it is found with Sidalcea malvifora var. Asprella , Erythronium hendersonii, and Vancouveria chrysantha with interspersed clumping Fescues. Long lived. This Iris among other Pacifica species do not compete well with invasive weeds and grasses. They are native to a fairly invasive free and less competitive balanced biome. Protect them by not allowing weeds grasses from getting a foothold around this Iris. Mulch with gravel to assist. Not bothered by deer or rabbits. Not as floriferous as other species but the flowers which are larger are much showier as well. Drought adapted. Oregon native plant.
Clackamas Iris is a rare endemic to only three counties in northern Oregon. Though it appears in scale with Pacific Coast Iris, it is not related and is more closely aligned with bearded Iris. Pale green 15mm wide leaves first emerge vertically before settling to a more horizontal position. Light lavender buds unfurl to white with yellow on the falls in May-July. In its native range this smaller iris is everywhere which begs the question; Why isn’t its natural range larger? Not bothered by deer or pests this is a supremely climate adapted perennial. To 12″ tall in bloom the arching leaves equal that and spreads out. Light consistent summer water to establish, then only what falls from the sky. Full sun to quite a bit of shade. In habitat it is an understory component with Sword Ferns and shrubs such as Hazel, Oso Berry, and Viburnum. Provide deep rich soil and room to spread. This Iris makes very large colonies quickly- to 3′ wide. The broad leaves are winter deciduous. Wonderful Iris for gardens and wild areas. Oregon native plant.
Kind of an obscure Pacific Coast Iris that Greg claims is a little more orange with brown striations than this picture depicts. Grassy leaves are evergreen and in May/June a continual parade of multi-colored flowers on 14″ cantilevered stems. Very easy to grow west coast native Iris hybrid that increases its bloom as the clump increases. The orange/ and maroon/cranberry flowers are visible from a distance and are particularly fetching when back lit. Completely deer and rabbit resistant perennial for part shade to full sun. Rich to average soil. Water diligently for the first summer, in subsequent years leave it strictly alone. Wonderful between and near Manzanitas, other west coast drought adapted shrubs.
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 20 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. An 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. Oregon native plant.
One of the most striking pacific coast cultivars. Large somewhat flat flowers are a saturated orange/ rust color with contrasting purple nectary guides. Excellent plant that is not only extraordinarily heavy in bloom it blooms the LONGEST of any PCI that we grow. Often repeat blooming 1-3 times following the grand first display. Grassy evergreen leaves form spreading clumps to several feet wide. The large flowers rise on 10″ stems. Loved by pollinators. This intense flower color and propensity for heavy bloom endears this wonderful cultivar to gardeners and its often on the list of favorites. Full sun to light shade- ideally it may be grown best in an open north exposure. Such as the north side of a house with no overhead shade. Blooms late April-early June. Very deer resistant. Water consistently through the first summer than none in subsequent years. And once established it resents disturbance.
Astonishing flower color is one reason to love this large flowered Pacifica hybrid. Orange/coral/pink all morphed into one hue with a central zone of deep purple near the center. To 1′ tall and forming spreading clumps of evergreen foliage. Blooms April-June. The large flowers are showy from quite a distance. Part shade is ideal but endures full sun and tolerates total shade. Water regularly through the first summer to establish- the clump should increase by twice its size then none in subsequent years. Resents disturbance best left where it is to live. Great deer resistance. A very unusual color for a PCI.
Yellow is a special color for Pacific Coast Iris and this selection does a great job at producing profuse large luminous yellow flowers for an extended period. To 14″ tall and forming spreading clumps. The vivid flowers are showy from a distance and resonate with the candy-like colors of other Pacific Iris. Mix with ‘Blue Moment’ for a classic blue and yellow combination. This Iris also blooms simultaneously with the clouds of blue flowers of Ceanothus. And they appreciate the same cultural conditions- a late spring vignette that gets by on no summer water! Evergreen. Not fussy about soil. Water consistently through the first summer to establish (established Iris will double their clump size in the first summer). Then only what falls from the sky in subsequent years. Heavy bloomer in April-June. High deer resistance.
Not a very enchanting cultivar name but a useful and distinct flower color variant of Algerian Iris. This winter blooming species produces large pale lilac/ivory flowers from November-sporadically until March. The 4″ flowers are nestled in the grassy evergreen foliage but are a light enough color to read from quite a distance. This for is perhaps best planted with the species to produces contrasting flower colors for more depth. To 1′ tall and twice as wide in several years. Full sun to very light shade in well drained soil of average fertility. Not quite as cold hardy as the species but it has to get pretty damn cold (below 5ºF) for damage to occur and that just never happens. Long lived perennial. High deer resistance. Low summer water requirements.
Our first deliberate cross of two Pacifica species has yielded a real looker. Half Iris innominata and half Iris tenax. It inherits the incredible amount of flowers from the first parent which is yellow and more intricate markings and purple hues of the latter. Fun to grow colony producing grassy iris for full sun to part shade. Begins blooming in late April and continues for 3 to 4 weeks. Adaptable to many types of soil, including clay soils. Water regularly through the first summer to establish then none in subsequent years. This little iris ( to 8″ tall) is very wild looking and reminds us of natural hybrids that occur in the wild.

Pacific Coast Iris can be dodgy to divide. You have to do it at the exact correct time in the fall just before they grow roots for the new year. Even then it takes a careful and gentle hand to produce viable divisions that will grow on and bloom. Native warrior must derive its name from from its ease of division.

I found this naturally occurring hybrid at the intersection of the species Iris tenax and Iris douglasiana in the southern Oregon coast range. There are 11 Pacific coast species and finding a true hybrid with knowledge of the parents in the wild is rare. Pacific coast iris are most closely related to Siberian Iris. These guys crossed the land bridge from Alaska and speciated. Its still possible to cross Pacifica Iris with Iris sibirica. These are known as Calsib hybrids.
