The blue form of New Zealand Burr with finely divided pinnate evergreen foliage that forms a vigorous creeping ground cover. In summer 3″ stems support round white flowers that appear for several weeks. Easy to grow dense-growing plant to 3″ tall and covering up to 3 square feet in a year. Rich, well drained soil with regular summer moisture to speed growth and keep the appearance fresh. Best in part shade to shade- seems to resent hot sun and permanently dry positions. Excellent for a fast cover that blocks weeds and roots as it grows- perfect erosion control for steep shady slopes. Plant on 1′ centers for a fast cover. Adaptable to dry conditions when established.
Such a good good plant. The purple-foliaged New Zealand Burr covers the ground in pinnate dark purple foliage. Low spreading evergreen ground cover for full sun to part shade in rich, well drained, moisture retentive soils. Avoid compacted dry soils- it will die out. Instead provide an annual mulch of compost- put it right over the leaves and let the foliage grow up through it. This will give you a dense spectacular ground cover in scintillating purple. Excellent as an understory in containers as well. In summer sporadic 4″ stems support spiky maroon orbs- these are the flowers. New Zealand.
Bear’s Breeches is a standard perennial in our region for dry shady environs. And though the bold foliage is amazing we’ve been drawn to this form which turns it up a notch. Nearly 3′ long bold leaves are imbued with gold changing to acid green as the season continues. In early summer the fantastic white/mauve/grey chalice-like flower spikes rise to 4′ tall. Forms imposing clumps quickly in rich to average, well drained soil with light, consistent summer water. Takes dry conditions well and will actually resort to summer dormancy in extreme conditions. Evergreen to about 20ºF. Low deer resistance. Shines in the deepest shade.
Variegated Bear’s Breeches or just plain old Acanthus with dramatically white-splashed leaves. There is great contrast between the white and the dark green sections of the leaves/stems. In summer this spreading perennial produces a 3′ spike with pure white flower bracts enclosing the pink flowers. Its a big ol party chalice of goodness. Not the hardiest Acanthus (yeah- that might be good). Plant in a protected location with RICH, well drained soil- add compost and all organic fertilizer. Completely deciduous in winter here. Each leaf extends to 2′ long with intricate indentation- aside from the variegation. To 3′ across eventually. Excellent plant for containers. Protect containers from temps below 15ºF (move to an unheated garage, porch). Emerges in mid-spring. Mulch the crown in autumn for the first few seasons.
Outrageous Bear’s Breeches for hot and sunny aspects. Forms large rosettes of spiked intricate leaves that almost lay flat on the ground. In summer, enormous chalice-like soft purple blooms rise to 2′ tall. Each flower opens to reveal yellow petals. A beautiful combination. Full sun and rich, well drained soil with light summer water. Give this plant room and air circulation. It does not like to be crowded. Fully cold hardy and completely winter deciduous. Established plants can get by on less water. Moderate deer resistance. To 2′ wide in several seasons. Spectacular cut flower.
This is the locally native form of our wild yarrow. A rambunctious, easy to grow evergreen perennial for rough sites in well drained soil in full sun. Continuously from spring to autumn ‘umbels’ of pure white flowers rise 18″ above low spreading aromatic, finely divided ferny foliage. Most often it is green with variants that have gray foliage from time to time. Low water perennial that can even be used as a lawn substitute. A single plant spreads to several feet wide. Moderate deer resistance. Butterflies oh the butterflies. Oregon native plant.
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.
Of all the selections of our native yarrow this stands out for many reasons. The ‘umbels’ of flowers are a rich red which holds the color for an extended period. It fades only slightly to a rust red with time. Its vigorous and easy to grow. And it re-blooms reliably if spent flowers are removed. All the way until frost and sometimes longer. A very, very good long-lasting cut flower. To 18″ tall forming spreading colonies. Semi-evergreen. Low water when established in well-drained soils. Excellent to moderate deer resistance.
Nifty foliage perennial that can double as a terrestrial border plant (with regular water in rich, moisture-retentive soil) or submerged as a border perennial in a water pot or the edge of the pond. The majority of the spikey 3′ tall leaves are composed of cream/ivory streaks with dramatic stripes of deep green. The effect is ghostly and vivid from quite a distance away. Forms large spreading clumps in time. To 4′ wide when things are going well. Full sun to part shade. Flowers are not very conspicuous spikes that hide within the foliage. Completely winter deciduous- this is nice, it makes cleaning up in late winter/spring easy and and no fuss and the plant begins anew and fresh each season. Not bothered by pests. If sunk in a pond or water pot use heavy clay soil- like from the ground and mulch with a layer of gravel. Long lived plant. High deer resistance. AKA. Ghost Sweet Flag.
Is this the best form of golden sweet flag or what? We love the vivid yellow leaves on a dense and arching evergold perennial. Clumps densely but the foliage is born in fans and spreads out. To only 6″ tall but spreading to 1′ wide. Best in part shade and either permanently wet sites or regular consistent water. Mine makes a happy home on the north side of my house at the base of the rain gutter. Plenty of water in winter- and I don’t forget to water it in summer. Good appearance year round. In spring little off-white spikes serve as flowers. Native to permanently wet sites. Give it a bit of shade. Moderately deer resistant.
