The Influence of China on West Coast Gardens: Connecting to a Strong Cultural Heritage

The Presidio, San Francisco

Eighth design seminar and study tour in the Garden Conservancy’s series, Gardens to Match Your Architecture. Co-sponsored by the Garden Conservancy and Pacific Horticulture.

A subtle richness of design that reflects China often pops up in gardens made on the West Coast. Spatial arrangement, architecture, fence and gate detail, rock alignment, ponds, paving patterns, choice of plantings and their sequence (a careful combination of understory and overstory), and the ideas behind a “contemplative garden” borrow from Chinese and other Asian aesthetics.

Gardens That Re-Make Themselves: A Discourse on Regeneration, Sustainability, and Preservation

Los Angeles Country Arboretum and Botanic Garden, Arcadia, CA

Seventh design seminar and study tour in the Garden Conservancy’s series, Gardens to Match Your Architecture. Cosponsored by the Garden Conservancy, The Los Angeles County Arboretum & Botanic Garden, and Pacific Horticulture.

In the world of fashion, clarity of design and great fabric bring lasting style. Applying that same clarity to the process of garden design should also create a long-lived garden that subscribes to the principles of sustainable and ecological design and is beautiful. Good initial selections of plants, garden materials, and infrastructure systems should lessen the burden of maintenance. The presentations will run the gamut of new public and residential landscapes to mature residential gardens that have withstood the test of time and are deserving of continuing preservation.
