Big and arching evergreen shrub that becomes an unbelievable sea of ultramarine blue flowers in April. To 8′ x 8′ very quickly in full sun and well drained soil. Amenable to clay if unwatered in summer. Once established NO summer water at all. Grows quickly to its ultimate size give it room. Leaves burn below about 12ºF but recovery is rapid in spring and seldom sacrifices blooms. Rapid growing in our climate it consorts well with native wildflowers and especially bulbs. Completely drought adapted in our climate. One of the most stunning wild lilacs ever released. Pictured below at an elementary school. Planted on the playground, the children use it as a shelter. Kind of cool.
This is one of the most popular shrubs in western Oregon of the last two decades. And rightfully so. This wild lilac sports excellent cold hardiness, prolific flowers, and glossy handsome evergreen foliage year round. A strong growing shrub that can literally explode in growth in rich soil but is much more restrained in poorer mediums. Remember this when planting it. It performs the best in average, un-amended soils in full sun with regular summer water for the first season to establish and then none in subsequent years. Sky blue flowers are profuse covering this dense shrub in a haze of color for 3-4 weeks in May to June. Later blooming that most other Ceanothus. This good looking shrub is so durable its made its way as highway verge mass plantings but it is just as stellar of a garden plant as well. Cold hardy to about 5ºF- it survived -5ºF in the southern Willamette Valley in 2013 by freezing to the snow line and then vigorously re-sprouting. Durable, dependable Ceanothus. Avoid the summer heat + water that it abhors- it leaves it open to root water molds that can do it in and fairly quickly. Excellent shrub for the beginning gardener. Loved by pollinators of all kinds and is virtually rolling in bees during its fabulous bloom. NOT DEER RESISTANT. Most likely a hybrid with C. thyrsiflorus which must be responsible for at least half of its make up. Found in Victoria, Canada- hence the name. Likely it is the old cultivar ‘Skylark’ that was re-named upon its survival there of a hideous winter. The old name was forgotten and the glee of survival and discovery led to the renaming. To be clear ‘Victoria’ and ‘Skylark’ are exactly the same thing. Very fast growing to on average 8′ x 8′. Excellent with all west coast natives. Blooms simultaneously with yellow Halimiums. A fantastic floral and cultural combination.

One of the cold hardiest blue flowered cultivars and one of the earliest to bloom as well. An open spreading shrub with prickily deep green leaves. In March/April the whole shrub is obscured in violet blue clouds of flowers. Upon first viewing in bloom most people are shocked at how showy this evergreen shrub is. To 7′ x 5′ in five years in any well drained soil with little to no summer water. Very adaptable to clay soils, especially on slopes- as with all Ceanothus avoid boggy sites. One of the toughest cultivars that also takes very well to pruning which should be done after blooming to increase density if needed. Blooms on wood from the previous year and the button shaped flower clusters are so profuse that they obscure the foliage. Tolerates blasting reflected heat and is great in hot urban situations. And makes a wonderful informal hedge for wild areas. Full sun. Moderately deer resistant- unusual for a Ceanothus. Cold hardy to 0ºF. The cultivar name might obliquely refer to the flower color but its an apt comparison to this tough , tough, shrub as well. No summer water.
A UK selection of our own west coast native wild lilac. And they did a good job. Large mounding evergreen shrub that puts on a spectacular display of deep blue flowers for nearly all of April into May. Fast growing to 5′ x 7′ very quickly in average well drained soil. Little to NO summer water. This cultivar has HUGE trusses of scintillating blue flowers. The largest of any Ceanothus that we grow- the reason why it is such a brilliant plant in bloom. Loved by pollinators of all kinds and especially tempting to large black and yellow bumble bees. Prune after blooming if you need to re-size the plant. Good cold hardiness. Best in a hot aspect. Good job to our friends in the UK.
We’ve been impressed with this extraordinarily deep blue flowered Wild Lilac released by Suncrest Nursery. A fine textured deep green evergreen shrub to 4′ x 8′ and forming a graceful cascading dome. Profuse cobalt blue flowers appear for 2-3 weeks in April. Extremely drought tolerant shrub for full sun and average to poor well drained soil. Little to no summer water required. Locate out of the path of subfreezing gorge winds. One of the most graceful and showiest of the genus. Grows very quickly to its ultimate size. Excellent performance on steep hillsides. Covers the ground like an umbrella with an great, intense, flower color. Excellent underplanted with yellow Pacific Coast Iris.
For cold gardens this is an excellent cultivar and its a version of a species native to the Willamette Valley south into California. Small green wedge shaped evergreen leaves on an arching, somewhat angular shrub. In April and May clouds of soft violet blue flowers swarm the whole shrub. Beautiful. To 7′ x 7′ very quickly in poor to average well drained sites. No summer water once established. Handsome at all times. Excellently adapted to rough urban life where compacted soils, reflected heat and little water is present in summer- thrives in all those conditions. Full sun. Easy. Surveys by the California Chaparral Institute report that this is the most common component shrub of that community in both California and Oregon. Fixes nitrogen with its roots and is common following disturbance. Classic west coast shrub. Oregon native plant.
This is a Willamette Valley native form of Buckbrush found in the SW part of the Valley. This species is found historically from the Portland/Oregon City area in the Willamette Valley and throughout the southern half of the state well into California. It has lost large areas of its northernmost natural range to development. Thats a pity because this is a fantastic native shrub for hot dry sites. It is now employed by ODOT for freeway plantings and we are happy to see that. A large, angular evergreen shrub with small deep green paddle shaped leaves. In April the whole shrub is swarmed with pure white flowers.This is a beacon to all pollinators and the sweetly fragrant flowers will literally be buzzing in bloom. Fast growing incredibly tough shrub for areas of intense drought and reflected heat. To 8′ x 8′ very quickly in any soil that does not become boggy. Excellent performance in tough urban situations. Irresistible to bees and butterflies. Extremely cold hardy to below 0ºF. No summer water. Moderate deer resistance. Oregon native plant.
The glory of this large, wild evergreen shrub occurs in April when the branches are awash in deep violet blue flowers.The darkest hue among this species. A fast growing very large shrub to 4′ tall by 12′ wide in time. Excellent for wild uncultivated areas. A handsome spreading deep green evergreen of great drought tolerance. Tolerates most soils that never become boggy. Good cold hardiness to 5ºF. No summer water when established. Loved by bees and butterflies. Takes well to pruning. Blooms on wood from the previous year, prune if needed after blooming. Excellent pollinator shrub for steep hillsides, rough areas. Evergreen foliage is handsome year round. Tolerates part shade. Blooms best in full sun. Photo below by Evan Bean.
The most popular ground cover Ceanothus and an important plant in our climate. Evergreen ground cover shrub that covers the ground densely. In March the entire plant is smothered in light violet blue flowers. Stems root where they touch the ground making it a valuable erosion control. Full sun to light shade in any well drained soil. Excels on steep slopes. To 10″ tall and 3′ wide very quickly. Plant on 3′ centers for a fast dense ground cover. If the shrub grown as a ground cover gets too tall it may be sheared after bloom has ended. Water to establish for the first season, this also speeds growth. Excellent performance in Hellstrips. Little water once established. Moderate deer resistance.
Easily one of the showiest wild lilacs commonly grown in our climate. Tiny almost black/green warty foliage is completely covered by masses of foamy deep cobalt blue flowers for several weeks in April into May. One of the showiest cultivars. The depth of blue is amazing. Very few plants can match the intensity of the hue blue. Fast growing evergreen shrub to 6′ x 8′ in three years. Full sun and average, well drained soil. Light consistent water to establish then none. Site out of subfreezing east wind which will not kill it but can burn it badly. Easy, spectacular, fast, west coast native shrub. Note: The size of Ceanothus has everything to do with the fertility of the soil and access to water. Poor to average soil is best for a more moderate rate of growth and not as huge of a shrub.
