A fine form of our native Yarrow that has leaves that are a striking gray with pure, clean white flowers. A great combination. Spreads to form a low wide plant that is evergreen (gray). The flat clusters of flowers appear continuously from May to frost. More consistently if you remove spent flowers. The umbels, unusual for the daisy family, are loved by butterflies. Well, actually all pollinators. They are given a flat landing pad and tons of flowers- what more could you want. Excellent for low care areas where this romping perennial will happily out compete weeds and hold ground with very light amounts of water. Full sun and well drained soil. its best to double dig the soil to incorporate oxygen and de-compact the soil. Does not like compacted soil. Light but consistent summer water speeds growth and vigor. Otherwise very drought tolerant. Excellent on slopes. To 20″ tall in bloom on a low spreading foliage plant to 2′ wide or wider. High deer resistance. Great cut flower. Mix with other low water plants. Pretty with other colors of yarrow. Oregon native plant.
New Mexico Agave is a spike wonder. Much more upright-growing than the species with sharp-tipped leaves that terminate in a blood red thorn. OW. Forms a very symmetrical plant with many leaves of steel blue. Full sun and VERY WELL-DRAINED soil. Excellent on hot slopes where it will tilt the rosette to avoid winter wet. Pups, heh, freely and you will soon have many rosettes. Amend the soil with pumice and gravel. Make sure there is plenty of air in the soil and no place where water could collect. Fantastic specimen plant for a dry garden/gravel garden. Water through the first summer to establish then none in subsequent years. Clean out the rosette when deciduous leaves collect in there- a shop vac works great. The leaves will cause rot when they decompose….so they must go. Great in containers- large, sturdy containers. Cold hardy. High deer resistance.
Consistently one of the most successful Agaves for gardens in our region. Soft gray rosettes have leaves with a distinct upright habit. At the tips of the wide leaves is a single (deadly) black thorn. Very nice. Full sun and very well drained soil with little to no summer water when established. This Agave requires soil that is never soggy- amend heavily with pumice and gravel to create air pockets. Plant this (and all) hardy Agaves in our climate on a tilt. The tilted rosette sheds rainwater and it keeps it much drier in winter. Ideally, this Agave should be sited on a hot, south facing slope. In autumn deciduous leaves from (everywhere) seem to blow into the rosette and collect. You must remove these immediately so that they do not rot the center of the plant. A shop vac works wonders…so do bar-B-Q tongs. Excellent in containers. Its best to plant hardy Agaves in early spring to early summer. They require a long season to develop a tap root which in turn ensures that they are cold hardy. No tap root and not so hardy. Hardy below 0ºF when dry. Highly deer resistant.
Excellent garden-tolerant smaller Manzanita. New growth is blushed pink as are the winter flowers. Settling to soft gray, this dense rounded plant achieves about 3′ x 3′ in 7 years. The bark becomes reddish and shaggy with age. Full sun and very well drained soil with no supplemental water once established. Gray foliage is organized symmetrically around the thick stems. This is a good scale for smaller gardens and a handsome shrub at all times. Provide good air circulation in an uncrowded environment. Long lived.
Our very, very favorite Manzanita and one of the very rare ones in the wild. Occurs on two ridges in northern California- Horse Mountain was one of them and Greg’s dad just happened to have a cabin there. Low, dense, spreading, very gray shrub to 3′ x 5′ wide in time. The bark is a great glossy mahogany and the winter/spring flowers are white tinted pink. Russet berries are quickly consumed by wild life. Spectacular shrub for full sun, average to poor, well-drained soil and absolutely no summer water. Loathes the combination of water and heat. Neglect is its friend and you will reap great rewards with this beautiful shrub by strictly ignoring it once it is established. Ultra cold hardy- hailing from over 4500′ in elevation and recommended for cold gardens. This species is native to southern Oregon, and though not technically native to Oregon this is our favorite form of this species. Not the easiest to propagate so quantities are often limited. Absolutely NO summer water. Ever. Forms rounded balls of soft silver. Dynamic on slopes.
Immensely handsome dense rounded Manzanita that has smaller than average silver foliage and fantastic bark. Moderately fast growing shrub to 6′ tall x 8′ wide in 8 years. In late winter each branch tip is bedecked in clusters of small white flowers- they are born in profusion and expand from pink buds. Russet colored berries often follow and are consumed by wildlife. The black/mahogany glossy bark is beyond striking with the silver foliage. It splits, rolls up into ribbons, and exfoliates in late summer. In time it may be pruned to reveal trunks–for most of its youth they are hidden by dense almost formal looking foliage. Adaptable to many soils including clay soils- especially on slopes. Excellent long term landscape plant that looks great year round. Very good cold hardiness enduring 0ºF with no problem. Dig a hole 3x as big as the rootball in the pot to loosen the soil and allow the new roots to penetrate virgin soil. Water regularly through the first summer- then little to none in subsequent years. Combine with green leaved Arctos for great foliage contrast. Perfect on slopes, areas with intense reflected heat such as parking lot planter islands. Great urban shrub. Appreciates good air circulation.
Ghostly white foliage is almost too pale to believed and ‘Ghostly’ is an apt name. A moderate growing Manzanita to 8’ tall and 4’ wide in 5 years. Fast growing in our climate. Do not be afraid to cut back lanky new growth for a more upright and sturdier plant. Prune in July. In late winter and early spring clusters of white urn shaped flowers appear at the branch tips and delight hummingbirds. There is no more silver/white foliaged Manzania that we have seen. Truly spectacular in well drained soil with good air circulation and little summer water once established. From a species native to the Santa Cruz Mtns. in California and surprisingly cold hardy.
Wonderful low spreading Manzanita that we have grown for more than 20 years. Silver/gray pointed leaves densely clothe the spreading stems of this adaptable shrub. In time the lax, decumbent stems point upward at the tips. In spring white flowers are a bonus. To 2′ tall and 6′ wide it may be employed as an informal ground cover. Full sun to light shade and well drained soil of average fertility. Little to no summer water when established. Nice looking plant year round. Excellent on slopes. Takes more shade than most cultivars. Excellent cold hardiness.
We sowed the seed and I’ll be damned if hundreds came up. This remarkable form of one of our favorite Jack in the Pulpits. Deep brown hoods host an interior spathe of pure white It looks like a little ghost rising up. Adorable. The large trifoliate leaves on this form are marked on the interior with a zone of silver. All together a fantastic look for a woodland perennial that requires deep, rich, well drained soil and ample summer moisture. Shade. Emerges late in spring- be patient and the way the bulb grows underground it means that it can wander a bit each year. Multiples when happy to form clumps. Completely winter deciduous. To 20″ tall.
Lovely, soft gray curls make up the foliage of this low spreading perennial. Easy to grow and long lived plant for full sun and well drained soil. Little summer water when established. Takes the hottest aspects with aplomb and remains good looking all season. At the end of summer stems extend to produce small white flowers. Not really showy but it expands the overall texture of the plant. Completely winter deciduous. Cut back hard in early spring. Forms woody stems at the base and is a quite permanent plant. Flows in and around other plants gracefully. Moderate deer resistance. To 1′ x 3′ in a season.
