Our Philosophy

IMG_6071.jpg

"It will be as if we were never there - only better."

We strive to create the most verdant landscapes by imparting a holistic approach to each setting. As Earth's ambassador our goal is to seamlessly

unite a site's existing characteristics with the perfect plan.

Nature Dictates Design

A design begins with one's needs, desires. From there we look to Nature.

We believe that both Human Nature and Mother Nature are of the utmost importance when developing a new or existing garden.

Plan(t) Perfect

Healthy plants are beautiful plants. Beautiful plants make

a garden exceptional. We create healthy, beautiful plantings

using a site-specific plant approach.

Green Leaves

“Jenna, as I watered today I was struck by your genius. You are a truly talented designer, plant savvy, but with tremendous style. Who would think of tearing all the leaves off the good plant to make it match the dead one? THAT is genius. Also, how did youfind the welded tree branches to prop up the conifers at the pool? They look great, as does everything. It is official, you will be doing the pots at BBF in the future. Thank you, thank you.”

Wooden sink

"Good morning! Just toured the garden and am filled with gratitude for your work and presence. Even though I am a gardener, I need compost and inspiration– new ideas and sisterly attention. The bones of what you did all last year hold strong, much of what we planted is thriving. And I look forward to what is next. That little comphrey is up. The big leaf stuff (Brownwilla?) is coming up. Happy. Grateful."
