Making a garden friendly for both people and wildlife is the topic of the Friends of Hilltop Arboretum annual symposium scheduled for Saturday, Jan. 16.

Tickets are on sale for “The Living Landscape: Designing for Beauty and Biodiversity in the Home Garden,” which will feature Rick Darke, a landscape design consultant, and Doug Tallamy, a professor in entomology and wildlife ecology at the University of Delaware.

Tallamy is author of “Bringing Nature Home: How You Can Sustain Wildlife with Native Plants,” and Darke authored “The American Woodland Garden.”

At the symposium, Tallamy and Darke will team up to show home gardeners exactly how to make a garden friendly to both wildlife and humans in a gorgeously photo-driven, inspirational and practical way.

The authors will explain the importance of each layer — ground covers, perennials, shrubs, understory trees and canopy trees — and show how they work in a healthy functioning ecosystem and how they can work in your garden. Many examples will be provided to inspire those attending to create a home landscape that is diverse, visually satisfying and sustaining on many levels.

Participants will be able to shop the Hilltop Garden Book and Nature Shop during the symposium and buy plants. A list of plants that will be available will be posted at one week before the symposium.
