Peter moved to Colorado from Vermont in 2021 after an injury ended his Continental Divide Trail thru-hike. He grew up guiding wilderness trips and working on farms, which still shapes his approach today. That same year, he founded Green Mountain Outdoor Living and met Sarah—she now supports the business behind the scenes while staying home with their 10-month-old son. They’re also excited to be welcoming a baby girl this September.

We’re a Boulder-based landscaping company focused on xeriscape gardens, native plantings, and outdoor living spaces that work with Colorado’s climate, not against it.
We started as a hands-on gardening and maintenance company, rooted in weed control, soil health, and native pollinator gardens. That foundation still drives everything we do today. Whether we’re building a full outdoor space or installing a planting plan, we approach every project with a deep understanding of how landscapes grow and evolve over time.
Our work ranges from targeted garden renovations and brush clearing to full-scale landscape installations, including patios, walkways, and outdoor living spaces built with natural stone and an emphasis on craftsmanship. What makes us different is how we integrate those elements with planting, soil, and long-term ecological health.
Planting is not an afterthought in our work. It is the foundation. We understand how plants respond to sun exposure, soil composition, drainage, elevation, and seasonal shifts in Boulder’s climate.
We design and install native and climate-adapted plant communities that support pollinators, create visual depth, and establish over time. Spacing, layering, and compatibility all matter. The goal is a landscape that fills in naturally, reduces maintenance, and looks better each season.
We take the time to understand your goals, walk the property with you, and offer thoughtful, realistic solutions. Every project includes clear proposals, aligned expectations, and follow-through. No surprises.
Water-wise landscapes should feel alive, not sparse. We build xeriscapes that are full, layered, and intentional, combining planting, grading, and materials into a cohesive outdoor environment.
Our patios, walkways, and outdoor living spaces are built with precision and care. Proper base preparation, tight joints, clean lines, and natural transitions into the surrounding landscape. The work is built to hold up, drain properly, and feel grounded in the space.
Healthy landscapes start below the surface. We pay close attention to soil structure, biology, and nutrient balance, using amendments when needed to support long-term plant health and resilience.
We take pride in doing the job the right way. That means attention to detail, consistency on site, and following through until the project meets our standard.
We bridge the gap between traditional landscaping and true horticulture.
We have the capacity to take on larger outdoor living and landscape projects, but we bring a level of plant knowledge and attention to detail that ensures those spaces feel natural, cohesive, and built to evolve over time.
The result is a landscape that doesn’t just look good when it’s finished.
It grows in, matures, and gets better year after year.
We’re not the right fit for every project, and that’s intentional.
If you’re looking for the cheapest option or a quick, surface-level solution, we’re probably not your company.
We don’t focus on traditional high-water lawns as the primary feature of a landscape.
We don’t build spaces that are purely hardscape without connection to planting and the surrounding environment.
We’re best suited for homeowners who value thoughtful design, natural aesthetics, and landscapes that evolve over time. People who care about plant health, craftsmanship, and doing things the right way from the ground up.
If that’s you, we’ll likely be a great fit.
