Design, Install, Maintenance — Petrus Landscape
When we began this project, it was a tired old landscape that had not been maintained for years. The client had expressed interest in developing French style gardens throughout the property, focusing on a hardscape entrance with dense plantings around the foundation.
French gardens often use cool colors in their plant palette and use lots of Boxwood and formal lines. We installed limestone flagstones for the entranceway with Elfin Thyme planted in between. A large marble fountain custom ordered from France was installed in the courtyard area.
Salvia ‘Amistad’ was planted around the foundation combined with ‘Limelight’ Hydrangeas and ‘Black Knight’ Buddlieias.

A deep understanding of Northern California landscapes

Climate & Ecology
We design with Northern California's Mediterranean climate rather than against it — reading each site's microclimate, soil, and light to select planting that thrives with restraint.

Architectural Context
Every estate is composed outward from its architecture, so the landscape feels inseparable from the residence — whether restored Spanish Colonial or contemporary design.

Long-Term Stewardship
The gardens we create are maintained by the atelier that built them, ensuring pruning, planting, and refinement follow the original design intent for decades.
