Garden Designer in The Dalles, Oregon

The Dalles sits at the eastern gateway of the Columbia River Gorge — where the canyon opens into high desert, the rain nearly disappears, and the gardening demands everything you know about dry-climate design.

The Dalles, Oregon is the largest city on the Oregon side of the mid-Columbia and one of the most historically significant communities in the Pacific Northwest. It is also one of the driest, averaging less than 15 inches of precipitation per year and enduring summers of relentless heat and east wind. For gardeners, this presents a genuine design challenge — and for Garden Riot Designs, one of the most creatively rewarding landscapes to work in.

The Dalles rewards designers who work with its climate rather than against it. Drought-tolerant design, native plant landscapes, gravel and dry gardens, and firewise landscaping are not just good ideas here — they are the only approaches that produce gardens that are genuinely beautiful and genuinely sustainable over the long term.

The Dalles Garden Conditions

The high desert climate of The Dalles is characterized by very low summer rainfall, high temperatures (regularly exceeding 100°F in July and August), persistent east wind, and soils that range from thin volcanic rocky ground to heavier clay soils in lower areas. The Columbia River provides dramatic visual context but also increases humidity slightly near the waterfront. Hillside properties above town face maximum sun and wind exposure and require the most careful drought-adapted plant selection.

What Works in The Dalles

The plant palette that thrives in The Dalles is one of the most visually striking available to any garden designer — native shrubs like big sagebrush, antelope bitterbrush, and rabbitbrush; perennials like penstemon, yarrow, and native asters; ornamental grasses; Mediterranean herbs; and the full range of sedum and sempervivum for ground coverage and green roof applications. These are plants that look their absolute best in high heat and full sun, and require almost no supplemental irrigation once established.

The Dalles is home to a growing wine industry, a strong agricultural economy, and significant commercial development.
