Springbank Clover. Fascinating perennial clover that was once widespread in wet areas of the Willamette Valley and is now found in restricted sites there but is much more prevalent on the coast and east of the Cascades. A pretty spreading spring wildflower with heads of brilliant magenta/purple flowers. Blooms in mid spring to early autumn. To 4″ tall it can be up to 2′ wide in favorable conditions. Though mostly restricted to seeps and wet areas now it once made life under native white oaks and there indigenous people would use it as a food source. The creeping green stems root where they touch the ground. Stems were harvested and steamed as a vegetable and they replanted as they harvested the remaining stems ensuring another crop. Not a long lived perennial 3-5 years but it sets copious seed. Wet sites in moisture retentive soil. Mainly riparian in habitat. It can dry considerably in summer and still thrive. But regular water is what it wants. Fun plant to grow that has lost a LOT of its native range. In habitat it is best seen on the wet cliffs adjacent to the beach. Great pollinator plant. Easily overwhelmed by invasive exotics. Oregon native plant.
Tea, the commercial source of black tea is a fine ornamental shrub in our climate as well. Its more than welcome in autumn when the small cup shaped fragrant white flowers peek from the stems. A rounded, good looking clean shrub with leaves that are deep green with more conspicuous venation on the surface. To 8′ x 8′ in 10 years for light shade to full sun. Great on an eastern exposure. Commercial black tea is produced by the fresh tips of the plant. These then go through a process of fermentation before it is edible. See more research. Easy to grow and somewhat more open than more commonly grown Camellias. And the leaves appear more matte as well. Regular summer water for the most verdant growth. Otherwise it accepts the same conditions as any Camellia. Blooms August to November. Blooms on wood from the previous year, prune if needed after flowering.
Slender Cinquefoil is a common, somewhat quiet but easy to grow long lived native perennial. Palmate leaves are conspicuously serrated on long stems. In early to mid summer 20″ stems support multiple clumps of sunny single yellow flowers. Full sun to part shade in average to enriched soil. Water to establish the first season then let it go with seasonal rainfall. Wild looking perennial that shines in borders, among shrubs and along the urban wild lands interface. Very pretty clustered at the foot of Holodiscus whose bloom is simultaneous. Loved by pollinators and an important food source for many butterflies. Native from SW. British Columbia south to San Diego County California. Often found in Ponderosa pine forests. Blooms much more heavily in full sun and improves under cultivation. Winter deciduous. Little deer resistance. Rose family. These are seed raised from Willamette Valley populations so it is the local form. Oregon native plant.
Sumptuous zonal geranium with deep black and green foliage and vibrant coral pink flowers non-stop for months. To 20″ tall and as wide. Seems to go up for a while but always ends up with horizontal stems. Blooms heavily and constantly- Very pretty delicate appearing flowers. This is a fantastic zonal for containers, its thrives in rich soil with regular irrigation. Rich, soil that drains. Add a table spoon of all organic fertilizer at planting. This guy loves food. Tender to cold. Over winter in an unheated but not arctic garage or try something new next year. This plant has become a real favorite of ours. Its also a fantastic conservatory plant and might work as a houseplant in a very sunny window. Full sun to very light shade.
Intriguing CLUMPING bamboo that rises to only 6′ tall but arches as wide. Fine, arrow shaped leaves protrude in the same direction giving an airy symmetry. Takes pruning very well and is recommended for small spots. In the open give it room to arch. The 1/3″ wide culms clusteer tightly forming a moderately fast increasing clump. After 10 years the base of culms will be no more than 2′ wide. Full sun to part shade to shade in rich soil with consistent summer irrigation. Established plants can take far less. Wonderful in a woodland or as an asian accent in themed gardens. This is a very hardy bamboo- tolerating temperatures slightly below 0ºF. A great bamboo for those in the line of east winds. Plant on 3′ centers for a dense hedge. Prune in spring if needed or allow it to gently repose with natural grace. Moderate deer resistance. SW China.
A very large growing, vigorous and pretty tree type Ceanothus native to the extreme SW part of the state. This fast growing evergreen tree (3′-4′ per year) puts on a huge display of soft blue flowers in late April to early June. Full sun to light shade (high overhead shade) and average soil that drains. Adaptable to clay soils, especially on slopes and not watered at all in summer. Completely drought adapted, no water necessary once established. To 18′ tall and half as wide in 7 years. Great screen, blue flowered tree that is beautiful in bloom but fades to a background for the rest of the year. Prodigious pruning can keep it much lower and it makes a great large hedge in no time. Good cold hardiness to 5ºF. We chose this variety in the wild because it was found quite a bit away from the coast which increases cold hardiness and it was immensely heavy in bloom. Prune AFTER flowering if needed. As a hedge or smaller plant it only requires pruning once a year- especially if strictly unwatered. Extraordinarily heavy bloomer. Pairs well with Madrone and Arctostaphylos. Oregon native plant.
Xera Plants Introduction
This handsome low growing and compact manzanita has great performance in our climate. Glossy mid-green foliage clothes a dense growing plant to 2′ x 4′. Admirable low ground cover as a massed subject but individual plants have glossy mahogany trunks that develop character with age. Masses of small white urn shaped flowers appear in late winter to early spring. Healthy looking at all times and not prone to black spot. Takes reflected heat well and even tolerates a light amount of shade. No water necessary once established, but it will take light water on slopes. Great small scale for small gardens. In time you can lift the plant up by pruning to reveal the small trunks. Long lived. One of the finest smaller varieties. Central CA coast.
Big, bold, and hardy, this is the cold hardiest Elephant’s ear that we’ve yet grown. Large (14″ long by 9″ wide) leaves with a distinct black dot in the center- the pearl. Large growing perennial to 4′ tall and running underground to spread as wide. Rich, moisture retentive soil with regular summer water. Excellent companion for other bold leaved plants- such as gold leaved Acanthus. Excellent for tropical effects w/ no fear of freezing out. Root hardy below 10ºF when clumps are established Give this large plant room to spread. Easy to grow for the most part. Goes deciduous with the first frost and emerges late in spring when the soil truly warms. Be patient. Not bothered by pests. Mulch for the first autumn. Great for big subtropical effects. Tolerates shallow water, but is not as hardy to cold.
Rare native perennial that can be found in wet marginal areas along the coast from Oregon to S. Alaska. Never common it forms large clumps of verdant green scalloped foliage and towers of deep pink hollyhock-like flowers. The flowers are arranged densely on the stem. Blooms repeatedly from June to frost- remove spent flower spikes to encourage more. To 34″ tall in bloom The best Checkermallow for rich, amended borders with regular summer water. Excellent cutflower and a beacon to pollinators-especially natives. Mostly winter deciduous. Combine with other tall spired perennials of similar culture. Very good with border delphiniums or even Penstemons. Tough long lived plant given the correct site. Climate adapted perennial. Rare. Cut back spent stems in winter. Oregon native plant.
This is red, no pink, very little orange, true blasting red. Our employee Chris thought we needed it and after observation I heartily agree. Bushy semi-woody perennial to 30″ x 30″ for full sun and rich well drained soil. A slope is best. Blooms unabated from May to frost. It takes a break in temperatures above 97º but resumes blooming with a cool down. This is redder ( with no white) than Hot lips with very large flowers in deeply colored calyxes. We have been impressed with the cold and wet tolerance of Salvia microphylla. Of utmost importance is to refrain from cutting them back until all danger of frost has passed, then you can go for it and regrowth to bloom is rapid. Obviously a hummingbird attractant. They stake them out, they fight and its all good fun. Long blooming Light deer resistance. Drought adapted when established.
