Fall is one of the best times to plant shrubs and perennials in many Western gardens, but knowing what to plant and when depends on where you live. Southern California’s warm, dry conditions call for a different approach than Northern California’s transition into winter rain or the Pacific Northwest’s cooler, wetter climate.
Whether you’re adding evergreen structure, seasonal color, or water-wise plants, choosing varieties suited to your local growing conditions can help you make the most of fall planting season. Explore the regional guides below to find the right plants and planting advice for your part of the West.
Southern California
Plant Now and Prepare for Summer
In much of Southern California, fall offers a welcome opportunity to plant after the intense summer heat. Cooler temperatures and still-warm soil can encourage root establishment before the following summer. However, coastal areas, inland valleys, and foothill communities experience different conditions, and hot, dry Santa Ana winds can continue well into fall. Choose a stretch of moderate weather for planting and provide supplemental water as needed while new plants establish.
When choosing fall garden plants, consider the conditions they’ll face during the hottest months. Safari Sunrise™ Aloe offers colorful fall-to-winter blooms in suitable warm-climate gardens, while Platinum Beauty® Lomandra and Coolvista™ Dianella bring year-round foliage and low-water needs once established. For compact evergreen structure, consider Beach Ball™ Pittosporum.
Northern California
Make the Most of Fall’s Planting Window
Northern California’s transition from dry summer weather to winter rain creates a valuable window for fall planting. However, timing and plant selection can vary considerably between coastal communities, inland valleys, and colder foothill locations.
‘Cool Blue’ Ceanothus offers variegated evergreen foliage and pale blue spring flowers, while Beyond Blue™ Fescue and Platinum Beauty® Lomandra add contrasting color and texture. In milder, frost-limited areas, ‘Meerlo’ Lavender brings fragrant, variegated foliage to sunny planting beds. Because ‘Meerlo’ is recommended for USDA Zones 9–10, gardeners in colder inland valleys and foothill locations should check local winter temperatures before planting. All four selections benefit from appropriate soil drainage, particularly during winter rainfall.
Before planting, consider both summer water needs and winter drainage, especially in areas where heavy rainfall or clay soil can leave roots sitting in wet conditions.
Pacific Northwest
Plan for Winter Moisture
In western Oregon and Washington, fall can be an excellent time to establish hardy shrubs and perennials while the soil remains workable and well-drained. However, planting conditions vary considerably across the Pacific Northwest. While wetter coastal and lowland gardens must account for winter rainfall and drainage, colder inland areas of Oregon, Washington, and Idaho face freezing temperatures, winter winds, and shorter fall planting windows. Choosing plants suited to your local climate and planting early enough for root establishment is especially important in colder locations.
October Magic® Ruby™ Camellia brings evergreen foliage and red flowers in fall, while EverColor® ‘Everest’ Carex brightens partially shaded spaces with green-and-white foliage. Baby Gem™ Boxwood provides year-round structure, and White Wedding® Hydrangea delivers large white flowers from summer into fall.
These selections are worth exploring in suitable Northwest climates. Check each variety’s hardiness and soil requirements, particularly in colder locations or planting beds that remain wet through winter.
Find the Right Plants for Your Fall Garden
Wherever you garden in the West, successful fall planting begins with choosing plants suited to your local climate, sunlight, soil, and water needs. Before planting, find your Sunset Climate Zone and check each variety’s USDA Hardiness Zone to better understand its suitability for your location. Remember that even water-wise plants need supplemental moisture while establishing, and newly planted shrubs and perennials may require extra attention during fall heat, dry spells, or prolonged winter rainfall.
