Expertly Designed Landscapes and Sustainable Gardening Solutions


Initial Design Consultation

We begin with an initial design consultation, during which we take the time to understand your vision and goals for your garden!


Concept Drawings

Based on our consultation, we’ll then create 2-3 concept drawings, which serve as the foundation for your design plan.


Preliminary Design Plan

We’ll work closely with you to make any necessary revisions to the concept drawings and create a preliminary design plan.

Specializing in Native Plant Selection

Here at Trillium Landscape Design, we aim to create not just strictly visually appealing outdoor spaces but also ones that are sustainable and compatible with our Pacific Northwest environment. To achieve this, our expert team chooses primarily native species sourced from local growers, often using a plethora of drought tolerant plants & pollinator plants.
