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 of purple with blue tints. Excellent as an understory in containers as well. In summer sporadic 4″ stems support spiky maroon orbs- these are the flowers. Best as a small scale ground cover, 3’x 3′ is reasonable. It will flow around low shrubs such as Hebes and around paving stones. Regular water. New Zealand.

Loquat is much hardier than most people think. Enormous specimens are ancient and scattered around Portland. In my previous garden I had a huge specimen that sailed through the worst winters (below 10ºF) and epic ice and snow with NO damage. Bold, broadleaved evergreen tree. The leaves are huge and look very tropical. In winter buds clad in brown fur support many very fragrant white flowers. Loved by overwintering Anna’s Hummingbirds. If the winter fizzles out and temperature fails to drop below 20ºF you may see the small, sweet fruits ripen in summer to early autumn. They can best be described as watery apricots. Primarily it is grown for its great foliage and convenient size. To 18′ tall and 10′ wide forming a rounded crown in 10 years. Full sun and rich to average soil. Completely drought adapted but summer water will increase the growth rate. Hardy to 5ºF . Avoid growing this tree in the windy eastern exposed suburbs of Portland. Excellent tree for a small garden.

Rich, moisture retentive soil in part shade to shade. It doesn’t go green in shade either- remains vibrant. Excellent woodland focal point and adaptable to permanently wet sites. Long lived easy to grow perennial.
Pacific coastal strawberry is a beach native- in fact it occurs all around the Pacific Rim and makes an adorable and durable ground cover on sand dunes. Well this version is like the giant hulk of strawberries. Huge in every way and vigorous? Wow, plant and get out of the way. The large glossy evergreen leaves are up to 6″ across and the single white flowers in spring and summer (sometimes in winter) are large also. The paltry fruit that follows is far from edible. It won’t kill you but you really have to like sour and gritty with millions of seeds. This is an ideal ground cover for rough sites in full sun to part shade. Don’t bother enriching the soil that will just make this trailing monster roar. Instead err on the side of a little neglect and watch what this native plant can do. Be wary of delicate plants in the vicinity. Evergreen, easy and drought tolerant. Oregon native plant.
Haute edible gardening meet haute ornamental gardening. This cheerful and bright woodland strawberry sets shade alight and continuous small white flowers turn into tasty red berries all summer long. Pair in part shade with Hakenochloa macro ‘All Gold’ Japanese forest grass for a great color echo and contrast in leaf shapes.

Very natural lining woodland paths. Semi-deciduous to winter deciduous. Native to the Portland city limits. Oregon native plant
Broadleaved strawberry or mountain strawberry is a widespread native species with large white flowers in spring that turn to small delicious red fruits in June. A low spreading perennial that also spreads liberally by runners. This tendency ramps up in richer conditions. This tough native form was found by our employee Brandon at Mt. St. Helens. This clone shows impressive vigor and is useful in a number of ways. A tough species that naturally thrives in clay soils (and clay strawberry pots). It competes admirably with grass and is best between native clumpers. Associated plants in the Willamette Valley are Dichelostemma congestum, Carex tumulicola , Lathyrus nevadensis, and Calochortus tolmiei. Mostly evergreen with many bright red leaves in winter but leaves remain present in all but the coldest situations. In the garden give it rich to average soil and regular irrigation to establish. This variety has enough summer drought adaptation that it will grow sufficiently with little summer water. Cold hardy, tough little plants. Bears one crop of fruit per year.
