Portland, OR · Plant guide

Plants for Portland.

Portland gardens can build a layered edge from vine maple and serviceberry, with evergreen huckleberry and tall Oregon grape below. Oceanspray needs patience and room to establish its loose form; western sword fern is the ground-layer choice for shade and organic soil.

Match canopy moisture

Use sword fern, Oregon grape and vine maple where shade and soil moisture fit; sunnier vine maple may require extra irrigation.

Allow natural forms

Serviceberry can sucker, oceanspray establishes slowly, and shaded vine maple spreads broadly; give these forms room instead of forcing narrow outlines.

Vine maple

Acer circinatum

Vine maple suits a spot where its branching shape can be seen. Allow for a large shrub or small tree, and match its moisture needs to the planting site.

Sun

Sun to deep shade; prefers moist shade and also tolerates sun.

Soil & water

Moisture-retentive soil; plants in sun may need extra irrigation.

Full-grown size

10-30 ft tall, with the larger sizes reported in western Oregon landscapes.

Through the year

Deciduous; foliage can turn red, orange and yellow in fall, especially with sun.

Winter hardiness

Hardy to USDA zone 5, with some reports extending into zone 4.

Moist, well-drained, acidic soil.

Full-grown size

3-10 ft tall.

Ordinary garden soil; accepts well-drained to dry sites.

Full-grown size

4-15 ft tall.

Plant references

Evergreen huckleberry

Vaccinium ovatum

Evergreen huckleberry keeps its leaves through winter and can grow much taller in some settings than others. Ask about the conditions it was grown for before fitting it into a small bed.

Sun

Full sun to part shade.

Soil & water

May need extra moisture while establishing; no fixed irrigation interval is available.

Full-grown size

Usually 3-5 ft tall, sometimes 8 ft and occasionally up to 15 ft.

Plant references

Western sword fern

Polystichum munitum

Western sword fern fills a shady bed with long green fronds. Give the crown space and keep the soil from drying out while the plant settles in.

Sun

Part shade to shade; full-sun tolerance applies only to a distinct named form.

Soil & water

Rich, organic soil with ample moisture; established plants can also tolerate dry shade.

Full-grown size

Fronds 1-4 ft long and 2-10 in wide.

Winter hardiness

Hardy to USDA zone 4.

Before you go to the nursery

Browse nurseries in Portland to find places to contact. Ask about the exact plants and varieties on your list before making a trip.

Bring a photo of the planting spot and its measurements. Note when it gets direct sun, how quickly the soil drains after watering, and whether you can water through a dry spell. Ask about the full-grown size of the exact variety on the label.

We have not confirmed local nursery listings for these plants yet. Use the botanical names above when you ask; common names can refer to more than one plant.
