CORVALLIS, Ore. — Mild days and cool nights in fall promise a spectacular show of color, especially when the weather brings a slow progression from warm to cool days and chilly — but not freezing — nights.
That weather pattern encourages dormancy in plants and leads to the breakdown of chlorophyll, the green pigment in leaves, said Neil Bell, a horticulturist with the Oregon State University Extension Service. As the green fades, brilliant autumn colors are revealed.
While trees often steal the spotlight in fall, shrubs offer equally rich color and beauty — and they’re easier to fit into a typical home landscape. Fall is a great time to take stock of what you’d like to add to your garden and either purchase plants now or take notes for spring. Most nurseries still have good selections in stock.
If planting now, make sure the soil isn’t saturated, and follow these tips for success:
- If roots are circling the pot, trim off the bottom mass and scuff the sides of the root ball.
- Dig a hole twice as wide as the root ball, but no deeper.
- Place the plant in the hole with the top of the root ball level with the soil surface.
- Backfill with native soil only — no compost or amendments unless you’re improving the entire bed.
- Water thoroughly.
To help you choose, Bell recommends these six standout shrubs for their brilliant fall foliage and multi-season appeal.
Burning bush (Euonymus alatus)
There’s a reason this shrub is so widely planted: its blazing red fall color is among the best. This adaptable plant tolerates a range of soils (as long as they drain well) and light conditions but performs best in full sun.
Winter interest includes ridged “wings” on the stems. Although often sold as a dwarf form under the name ‘Compactus’, it can grow 8 to 10 feet tall and wide. In the Pacific Northwest, it’s a garden favorite, though it's invasive in parts of the eastern U.S.
Hardy to USDA Zone 3.
Blueberry (Vaccinium corymbosum cultivars)
Best known for its fruit, blueberry also offers year-round beauty: white spring flowers, summer berries, and stunning fall color that ranges from yellow and orange to deep red.
Blueberries prefer acidic soil (low pH) and full sun. Amend soil with sulfur if needed. For a better harvest and showier display, plant multiple cultivars.
Hardy to Zone 5.
Bloodtwig dogwood (Cornus sanguinea ‘Midwinter Fire’)
This shrub shines in three seasons: fragrant white spring flowers, brilliant golden fall leaves, and red stems in winter. For best winter stem color, cut the shrub back hard in early spring.
To enjoy both flowers and stems, cut only half of the stems each year. Grows 5 to 6 feet tall and wide, prefers full sun, and needs regular water.
Hardy to Zone 4.
Doublefile viburnum (Viburnum plicatum f. tomentosum ‘Mariesii’)
This large shrub offers dramatic red fall foliage, rivaling burning bush. In spring, enjoy flat clusters of white flowers that resemble snowcaps. By summer, red berries appear, attracting birds.
With time and space, this viburnum forms a beautiful, horizontal branching pattern. Limit pruning to preserve its elegant shape. Grows 6 to 8 feet tall and 8 to 10 feet wide.
Hardy to Zone 5.
Witch-alder (Fothergilla major and F. gardenii)
Both full-size and dwarf forms of this native shrub dazzle with fiery orange-red fall foliage and white bottlebrush-like flowers in spring.
Best planted in full sun for strongest color, witch-alder likes moist, well-drained soil and fits well in borders, woodland gardens, or informal hedges.
- F. major: 6 to 10 feet tall and nearly as wide
- F. gardenii: 3 to 4 feet tall and wide
Hardy to Zone 4.
Panicle hydrangea (Hydrangea paniculata ‘Unique’)
Unlike most hydrangeas, this one provides fall color in both flowers and foliage. Its cone-shaped blooms start white and shift to soft pink by fall, backed by colorful leaves.
Blooms appear July through October, and since they grow on current-year wood, prune in early spring. Tolerates full sun better than most hydrangeas. Grows 6 to 10 feet tall and up to 8 feet wide.
Hardy to Zone 3.
