Seattle Metro & Puget Sound
Seattle's maritime climate is one of the most forgiving in North America for gardeners — mild winters rarely below 20°F, dry summers with virtually no rain July–August, and rich, often-acidic soil. The challenge is the dry summer: most plants need irrigation from late June through September without it.
Seattle Modern Native Garden
Pacific Northwest ContemporaryThe quintessential Seattle garden: Oregon Grape and Sword Fern as the bone structure, Red Flowering Currant for spring hummingbirds, Western Red Cedar on the perimeter, and a mix of Salvia and Lavender for the dry summer period. A rain chain from the downspout feeds a small gravel basin. Zero lawn.
Key Plants
Rainwater Harvest Garden
Ecological UrbanSeattle's 38 inches of annual rainfall can be harvested to irrigate through the dry summer. A rain garden depression near the downspouts collects overflow, planted with native sedges and rushes. A 300-gallon cistern feeds a drip system for the vegetable beds. The model for sustainable Seattle landscaping.
Key Plants
Capitol Hill Shade Garden
Woodland ShadeSeattle's older neighborhoods have mature tree canopy that creates dense shade. This design works with the shade: Japanese Maple for a specimen focal point, Hellebores as the workhorse groundcover (evergreen, deer resistant, blooms February–April), mass Hosta, and Brunnera 'Jack Frost' for silver foliage.
Key Plants
Edible Cottage Garden
Productive BeautySeattle's mild climate allows a 9-month growing season. An edible cottage garden layers kale and chard as ornamental foliage plants, blueberries as the foundation shrubs (producing August–September), espalier apple on a south-facing fence, and climbing beans on a beautiful cedar trellis.
Key Plants
Eastside (Bellevue, Kirkland, Redmond, Issaquah)
The Eastside's tech-forward culture has created high demand for sophisticated, low-maintenance landscaping that looks polished year-round. Slightly colder than Seattle proper, with more rain shadow effect as you move east. Deer pressure increases significantly toward Issaquah and Sammamish.
Bellevue Modern Minimalist
Pacific Northwest ModernClean architecture meets the PNW. Columnar English Oak as the vertical element, mass plantings of Amsonia 'Blue Ice' for summer blue and gold fall color, a linear water feature with basalt columns, and fine crushed granite paths between Japanese Maples. The garden as architecture.
Key Plants
Deer-Resistant Woodland Edge
NaturalisticIssaquah and Sammamish have significant deer herds. This design creates a deer-proof garden using fragrant, unpalatable plants: Russian Sage, Catmint, Agastache, ornamental grasses, and native ferns. Deer leave ferns and grasses alone. The result looks intentionally wild but is completely managed.
Key Plants
Redmond Tech Campus Home Garden
Refined Low-MaintenanceFor the busy Eastside professional. Drought-tolerant once established, automated drip irrigation, and evergreen structure that looks polished year-round without seasonal maintenance. Dwarf Alberta Spruce, Boxwood, Salvia, and a simple gravel path create a low-input garden that photographs beautifully.
Key Plants
Eastern Washington (Spokane, Tri-Cities, Yakima)
Eastern Washington is a completely different world from Seattle — a high desert with cold winters, hot dry summers, and only 15–20 inches of annual rain (mostly winter snow). Landscaping here requires drought-tolerant plants, efficient irrigation, and cold hardiness to zone 5a or better.
Spokane Xeriscape Garden
Water-Wise WesternSpokane's 17" annual rainfall demands water-wise design. Russian Sage and Lavender create the summer backbone, Rabbitbrush for fall yellow, Blue Oat Grass and Blue Grama for texture, and a layer of crushed basalt mulch that reduces evaporation and reflects heat away from plants.
Key Plants
Eastern WA High Desert Prairie
Western Native PrairieBring the Palouse and Columbia Basin native plants into your garden. Bitterbrush, Sagebrush, Idaho Fescue, Yarrow, and Blanket Flower create a garden that mimics the shrub-steppe habitat native to Eastern Washington. Adapted to the exact conditions without any irrigation after year one.
Key Plants
Yakima Wine Country Garden
Mediterranean DryThe Yakima Valley has a climate similar to Spain's Rioja region. Mediterranean plants — Lavender, Rosemary, Cistus, Penstemon, and ornamental grapes — thrive in the hot dry summers and mild winters. A gravel garden with terracotta accents evokes the wine country feeling.
Key Plants
Olympic Peninsula & Coast
The Olympic Peninsula receives up to 140 inches of rain annually — the wettest place in the contiguous US outside of Hawaii. This creates lush, Tolkienesque growing conditions where plants grow with extraordinary vigor. Drainage is the key design challenge; raised beds and gravel mulch are essential.
Olympic Rainforest Garden
Temperate RainforestEmbrace the extraordinary growing conditions of the Peninsula. Western Red Cedar as the canopy, Vine Maple in the mid-layer, Sword Ferns and Deer Ferns as the ground layer, and a carpet of Oxalis oregana (wood sorrel) and native mosses. A path of crushed basalt winds through the space.
Key Plants
Coastal Storm-Resistant Garden
Coastal NaturalisticPacific coastal exposure demands salt-tolerant, wind-hardy plants. Shore Pine, Kinnikinnick as a groundcover, Beach Strawberry, Sea Thrift, and native ornamental grasses handle the salt spray and fierce Pacific storms. Boulders and driftwood provide structure without wind resistance.
Key Plants
Washington native plants guide
Washington has two very different native plant communities divided by the Cascades. Western WA natives thrive in wet conditions; Eastern WA natives are adapted to high desert drought. Know which side of the mountains you're on.
