Consultation
Not a landscape company.
A landscape atelier.
We hold a singular conviction: the land surrounding a great estate should be as thoughtfully authored as every room within it.

Ward and his team approach every property as artists, not contractors. The soil is our canvas; stone, water, and living plant are our medium. We do not execute standard plans we compose original works, shaped entirely by the land’s character and your vision.

We accept a deliberately limited number of new estate partnerships each year. This is not a constraint it is our commitment. Ward is personally involved in every project from first conversation to final installation, and that depth demands focus.

We design landscapes that deepen in beauty over decades. A Petrus garden does not peak and fade it matures. The French palace gardens and English estate grounds that inspired Ward have stood for centuries. That is the standard we hold ourselves to.

Ward Dilmore
“I grew up watching farmland become forest. My parents were artists. Nature was always the canvas.”
Ward’s journey is unlike any other in the industry. Raised on land being slowly reclaimed by old-growth forest by parents who were both artists he developed an instinctive understanding that nature itself is a creative act. He studied horticultural technology at the University of Sussex, traveled extensively through the great estate gardens of France and the Mediterranean, and has spent over two decades working within some of the world’s most private and extraordinary properties.
His past projects include recreating French palace gardens, Mughal-inspired landscapes, and formal English gardens for Silicon Valley’s most influential families and celebrity estates from the Hamptons to Pacific Heights.

Petrus Landscaping was a delight to work with from design through installation. They installed an outdoor kitchen, pergola, new fence, and walkway that made our small backyard into an oasis. They also installed fruit trees and native plants, and an updated irrigation system.
Petrus Landscaping designed and installed a beautiful upgrade to the gardens on our property, giving it a more Mediterranean feel. The crew also repaired our complicated irrigation system. We found the team easy to work with, responsive and reliable. Petrus has continued to maintain the property, adding seasonal flowers and making everything look great.
Highly recommend Ward and his team.
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.
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.
