It is always a joy to work with Katherine and Jonah of Tributary. Their landscape additions to the built works I’ve designed always greatly enhance the building; they never fail to collaborate to make my products better and my clients happy.

I have worked with Katherine and Jonah for a number of years and have always appreciated their enthusiasm to take on out of the box problems. I especially like their native and drought tolerant projects.

The folks at Tributary listen to the desires of their customers, and find ways to integrate those ideas into a solid landscape installation. Tributary also carefully researches their suppliers before choosing materials. We enjoy working with Tributary, and highly recommend their expertise to anyone.

Katherine and Jonah create living art that is impressive on day one and grows more beautiful over time. Highly recommend!

Katherine is a rare landscape architect in that she truly has in-depth knowledge of plants. On the "Raleigh Police Memorial" project, she was a terrific collaborator with the other artists. The fact that the space still feels great three years later proves Katherine’s strengths in creating a sustainable and attractive space. She and her team are trustworthy and talented."
