🌿 SERVING AREA IN SONOMA VALLEY: The town of Sonoma and Glen Ellen
Single-Source Landscape Care, Now in Sonoma Valley
Penning Landscapes is a family-owned, single-source landscape firm that designs, builds, and maintains estate gardens across Napa Valley and Sonoma Valley. In Sonoma Valley, that means the town of Sonoma and Glen Ellen, the part of Sonoma County where Penning takes on estate maintenance work.
The same team that has cared for Napa Valley estates since 1988 serves Sonoma Valley from the Napa office. One team designs the garden, one team builds it, and that team maintains it, year after year.

Why Sonoma Valley Estates Choose Penning
One Accountable Team
Penning designs, builds, and maintains as a single source, so there is no handoff between a designer who leaves and a crew who inherits a garden they do not know.
A Maintenance Record that Travels
Penning holds 17 CLCA awards across 22 years, most for maintenance, including a 2022 statewide CLCA State Trophy. Sonoma Valley clients get the same standard and the same team that earned it.
Plant People First
The firm hires for horticultural depth before anything else, which is what lets a garden mature on plan.
QWEL-Certified Water Management
Penning manages the dry-season water constraint with QWEL-certified technicians on the team.
TESTIMONIAL
Penning's Sonoma Valley work includes the Glen Ellen Residence. Across both valleys the firm's maintenance record includes a 2022 CLCA State Trophy and a 2024 First Place for commercial maintenance.
"Ben Penning runs a very professional landscaping company. His knowledge of plants, landscaping materials, irrigation, lighting and design were all very helpful in guiding the implementation of my complete landscape renovation. His staff is conscientious and communicates well."
