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 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.
Greg and I found this distinctive form of Coast Blue Blossom in the wild. This species ranges from Lane County, Oregon to Santa Barbara County, California. A fast growing seral species that follows fire and disturbance. Very near the location where we discovered this handsome small tree was to the largest Ceanothus thyrsiflorus ever discovered in 1925- it was nearly 30′ tall. This is a large and fast growing evergreen tree with copious amounts of scintillating flowers. It has smaller deep green leaves and huge trusses of soft turquoise flowers in late April to early June. A tall growing tree/shrub that attains heights of 15′ very quickly if allowed. This drought tolerant native takes very well to pruning too- which should be done after blooming. Full sun and average well drained soil- including clay soils. Little to no summer water when established. Excellent for use as an instant screen or informal hedgerow. Pretty in the background of dry borders. Loved by bees and butterflies in bloom. Very easy to grow native evergreen shrub that should be used more. Life span 15-20 years. Oregon native plant.
Xera Plants Introduction.
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.
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.
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.
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.
Possibly the darkest blue flowering cultivar that blooms in the summer. This hybrid is technically supposed to be deciduous but for us it never has been. Large panicles of cobalt blue flowers erupt from the current seasons growth in June to July. Remove spent flowers and more may follow. To 5′ x 3′ in average to enriched soil with REGULAR summer water. Good drainage. Easy to resize as it blooms on new wood, it may be cut to as low as 18″ in early spring. Black seed capsules follow the flowers and persist until birds relieve them of their contents in autumn. Excellent in borders, as a specimen, or informal hedge-row. Not as drought adapted as most of the genus. This plant is best with consistent moisture through its bloom period- not boggy (ever) but consistent. Remarkable flower color- moody, deep indigo.
