The Petrus Difference

Landscape Design for Exceptional Estates

Led by Ward Dilmore

Ward Dilmore Founder of Petrus Landscape
About the Designer

At Petrus Landscape, each project begins with a guiding principle: outdoor spaces should be thoughtfully designed, harmonious in composition, and capable of evolving naturally over time. This philosophy reflects the approach of estate landscape designer Ward Dilmore.

With extensive knowledge of landscape design, horticulture, and spatial composition, Ward views every property as a distinctive canvas rather than a template to be repeated.

The outcome is more than a landscaped yard it is a carefully crafted outdoor environment that enhances the architecture of the home and supports the lifestyle of the people who live there.

Estate Landscape Services

A Complete Approach
to Landscape Design

Las Olas Atherton Luxury Landscape Design Project

Landscape Design & Master Planning

Each project begins with a comprehensive landscape plan that considers architecture, circulation, planting design, and long-term garden evolution.

Architectural Hardscape Design

Stone terraces, garden paths, retaining walls, and outdoor living spaces designed to integrate naturally with the home’s architecture.

Estate Garden Planting

Thoughtfully composed plant palettes suited to the Bay Area’s microclimates balancing beauty, structure, and sustainability.

Hillside & Complex Property Landscapes

From sloped terrain to multi-level gardens, Petrus Landscape has extensive experience shaping landscapes that require thoughtful engineering and design precision.

Sustainable & Drought-Tolerant Landscapes

Water-wise planting strategies that maintain beauty while responding to California’s environmental conditions.

Why Design Experience Matters

Landscapes That Improve With Time

A well-designed landscape evolves. Plants mature, spaces become more integrated, and the property develops a natural sense of place.

Without thoughtful design, landscapes often require constant rework.

With more than 30 years of landscape design experience, Petrus Landscape creates environments designed to grow beautifully for decades

Amazing service, really enjoyed working with the Petrus team to help us set up and keep the landscape in our properties looking stunning!

Hernando Quintero

Bay Area

Petrus Landscaping transformed our steep hillside yard with beautiful features like a stone staircase, pond, tiered garden beds, and drought-tolerant planting with an automated drip system. The team was professional, thoughtful, and delivered results beyond what we imagined.

Jenny Stewart

East Bay, California

I have been working with Ward, Gabe and their team of gardeners at my clients estate for the past 5 years. I have found them to be reliable, professional, and extremely knowledgeable of landscapes. They certainly know their plants, and have been instrumental in bringing a fine level of detail to the estate I manage. Their team of gardeners are respectful, attentive, and go above and beyond to create the well manicured gardens that the estate requires.

Darryl H

Estate Manager, Los Altos

Ward and his team completed two complex projects for our Silicon Valley client at their Sunnyvale campus. One involved redesigning a large atrium’s hardscape, requiring careful weekend transport of heavy materials through a newly renovated cafeteria—executed flawlessly without disrupting operations. They also revamped the main entrance planters, replacing an unsatisfactory installation with a more elegant and formal design. Their work is always thoughtful, precise, and completed with minimal disruption. We trust Petrus Landscaping for all large-scale projects, knowing they deliver exceptional results every time.
