Mary LeBlanc Landscape Design

Mary provides exceptional landscape design services. Our project was a substantial residential design in a difficult environment. Mary's knowledge of what plants will thrive under difficult weather conditions is insightful. She managed the entire project from design, assisting with selecting nurseries, along with providing detailed instructions for on-going maintenance. She is professional and easy to work with as well.

I highly recommend Mary LeBlanc for your landscape design and installation project. Mary was excellent at listening to my husband’s and my vision for our Cape property, including a few “wish list” items that we didn’t think would work, and created a beautiful design that somehow incorporated it all. She managed our entire project, keeping the contractors on task and making sure everything was completed on schedule, even though entire teams of individuals contracted Covid and were unable to work for weeks and supply chain issues arose. Our project was subject to conservation review and Mary managed that process extremely well. I really appreciated Mary’s deep knowledge of plants and learned a lot from her as she helped us restore our beautiful but overgrown perineal gardens and created some new ones. Mary is easy to work with, very organized and, lucky for us, a real task master! We couldn’t be happier with her work.

mary was the utmost professional contractor we worked with on your new home in osterville! she listened to our vision and the took the time to make thoughtful recommendations on the project. she educated us as to what would work in different areas of our yard and thought long term while holding our budget in consideration the entire time! we LOVED working with Mary!

Fantastic! We would highly recommend Mary. We brought Mary into our project at a very late stage, but she just jumped right into it with focus and enthusiasm. She not only gave us great ideas, but was also extremely helpful with key details, choice of materials and execution.

Mary LeBlanc Landscape Design has, and continues to provide my family with the highest level of professionalism, exceeding our already high standards and expectations. We have now been working with Mary for approaching 3 years now through various phases of our landscaping projects. She is highly talented, meticulous, organized, efficient and accessible. Mary is a very warm person who cares deeply about the project outcome, as the results clearly demonstrate. In response to our request, she connected us with some very talented and responsive landscapers, which made life much easier. We cannot recommend Mary LeBlanc highly enough for all of your landscape design needs!

Mary is an outstanding landscaper, photographer and communicator. Her design work surrounding a recent pool project of ours was second to none. Encompassing tasteful features, luscious grass and creativity, the client that we shared was thrilled with their results.

Dear Mary, We don’t know if we could thank you enough for everything you have done for us. The project is unbelievable and it would never have happened without you. I was a little skeptical when we first met because of our negative experience with our first attempt at getting this pool project for the house. That skepticism disappeared soon after we started working together. We love everything in the entire yard, front to back and the pool is beyond our expectations. You immediately understood the look we were hoping to achieve and we appreciated your understanding of our budget. We are blown away by the final result and so is everyone that has had a chance to see it. One of Nick's , our contractors, guys said to me near the end ”it looks like a different house” I said, it looks like someone else’s house! I hope the project fulfilled your expectations as well and we hope you are happy with the final result We would love to write a review on your web site or any other place you suggest If not this fall or winter we hope to see you again in the spring and summer Best Wishes Louis and Mary Ann Sent from

We so enjoyed working with Mary. She listened to what we were trying to achieve and had great ideas that turned out so perfectly. Mary's attention to detail, particularly in designing the whole project and in ensuring we would comply with conservation requirements was outstanding. Mary's on-site ownership of the project resulted in some great additions and in everything being done timely. Mary is a gem!

I hired Mary in January for what to me seemed like an impossible task. We met at the property once and after some design work, which was quite timely and also very clear so that we could go all in or pick sections, I asked her to get proposals for us. She did this, and helped select the best company for us. After a summer of enjoying the redesign which was also finished in advance of our expectations, I highly recommend Mary for any project. We have more to do but this helped us really decide if it was worth pursuing. Which we will. Having a cohesive plan with someone who helped me with my vision was better than I’d anticipated. Oh, and we found her on Houzz!

We had a complicated project with a lot of permitting required. Mary made the process easy from start to finish. She was thorough, organized, professional and expedient at every turn. We are so happy with the result and would use her again in a heartbeat.

The landscaping at our Cape Cod home is beautiful thanks to Mary's design and attention to detail. She listened attentively to our requests and preferences, offered wonderful suggestions for improvements and was on site throughout the project to optimize the execution of all aspects of the installation. Since we live halfway across the country, Mary had the added challenge of connecting with us long distance, but this was never a problem. Whenever we had a question, she was only an email or phone call away, responding to us quickly and professionally. We are very appreciative of all of Mary's effort and commitment to provide us a wonderful landscape that we will enjoy for years to come.

We hired Mary for a pretty extensive overhaul of the yard of our home in Cape Cod. She was extremely professional, thoughtful, patient and truly cared about our vision for the project. She was always available to answer questions (no matter how small!) and took our feedback seriously. Mary is an amazing listener and her project management skills are top knotch. We are extremely happy with how the project turned out and would highly recommend Mary to anyone seeking a landscape architect. Such a pleasure to work with Mary.
