About

Kim, Seattle

One of Jonna’s greatest strengths is her ability to truly listen. She thoughtfully considers everything you envision, from your preferred color palette to your placement on the "manicured-to-jungle" landscaping scale. She attentively incorporates sensory elements into her designs—blending fragrances, strategically balancing sun and shade, and artfully combining diverse textures, leaf sizes, and colors.
 
Jonna collaborates seamlessly with other contractors, communicates clearly, and consistently brings positivity to every interaction. I wholeheartedly recommend her exceptional talents to anyone seeking a passionate, knowledgeable, and dedicated landscape designer.
