Our Services.

We are passionate about designing with plants! The benefit they provide to biodiversity enhancement and the emotional connection to the wild they trigger in us all. We are currently volunteering many hours to the Potrero Eco-Patch, a community-led demonstration garden, where we have developed a series of San Francisco native plant mixes for testing.

In addition to typical landscape architecture services, we also offer our services as horticultural consultants and can supply arborist reports, tailored planting lists, schematic planting plans, full construction documentation planting plans, details, specifications, and construction support.
