Our Philosophy

Our Philosophy

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.




“Jenna O'Brien and her Viridissima team have been helping me with our gardens for the last 8 years. It has been 8 years of joy and pleasure. Jenna is prompt, reliable, well organized, always cheerful, and very hardworking. But much more than that she is a gifted designer and a curious and eager learner and explorer in horticultural subjects. She is the best thing in my garden.”

Georganne Rousseau

“I am so grateful to have found Jenna. She is very knowledgeable, thoughtful in her approach, efficient and so artistic. She has really transformed my gardens. She has a complete understanding of my needs in the garden and has wonderful ideas. I very much appreciate her work.”

Madeleine Miller

"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."

“Jenna is a treasure. She's an extremely knowledgeable plants person, who never ceases to learn about new varieties, different planting techniques and management regimens that keep plants looking their best, as well as the pests and diseases that are always threatening. She has a knack for making wonderful container displays, beautiful as well as productive vegetable gardens and spectacular flower arrangements. She also has a strong work ethic and is tireless in the garden. In addition, she's a good manager of people, who supervises and trains her staff very effectively. Finally, she is a delight to work with, always listening to others' ideas and opinions and inserting her own suggestions into the discussion with thoughtfullness and charm.”

Ian Hooper

“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 you find 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.”

Matt Larkin

“She adopts a holistic approach to gardening where the relationship between landscape and client is interconnected and harmonious. First and foremost Jenna is an excellent listener. She thoughtfully ponders and considers the concerns and desires of the client, makes suggestions, and is flexible and willing to change direction if needed. Jenna devises creative solutions and follows up with sketches and images of proposed plantings and designs, thereby greatly facilitating the process. Jenna and her crew have a great attitude, are serious and professional about their work and, in essence are a lot of fun to work with. My gardens have never looked so good!”
