The Bridge Between Horticulture and the Environment

(Professional & non-professional)

Dan Pearson

Horticulture is going through a revolution, as our fragile environment becomes increasingly in need of our care. The observation and analysis that is so embedded in this process, and the craftsmanship of tending for a garden, are perfect gateways to thinking about the neglected and overused places beyond the garden. Dan Pearson, whose painterly-naturall landscapes are renowned in Britain and beyond, will demonstrate how landscape design can be the medium that brings together the worlds of nature, agriculture, and garden.

Artful Plant Community Design: Selection-Arrangement-Stewardship

(Non-professional)

Larry Weaner, FAPLD

Selecting and arranging plants is central to - if not the heart of - fine garden design. Plant community-based design is no different; it simply uses natural vegetative models as its primary template. In this presentation, Larry will illustrate how to associate plants with their preferred environment, create plant compositions that function as integrated communities, and accommodate compositional change over time. But the word garden is not lost in this “wild” shuffle. He will conclude by revisiting fine garden design to show how an ecology-based plant palette can express, and even enhance, many different landscape styles.

Increasing Interest in Lenape Gardening:
A Native American Perspective

(Non-professional)

Clan Mother Shelley DePaul

Over the last year there has been a rising interest from various partners to provide information on Lenape plants and practice, and to consult on existing gardens in order to provide native species and medicinal herbs. This has come about at a time when it is crucial to instigate horticultural practices that will increase the production of organic foods, re-introduce native plants into the earth, and provide instruction on the use of medicinal herbs, all of which will help to ensure that the next seven generations of our children will be able to consume natural, nutritious food. This is the goal!

Designed Dutch Ecosystems:
Landscape Management Lessons from Heemparks of the Netherlands

(Professional)

Keenan Porter

Netherland’s Heemparks, public parks designed with native Dutch species to reflect local ecosystems, are a unique albeit understudied landscape typology. With more than one hundred established, most for more than fifty years, heemparks offer valuable precedents as to how naturalistic landscapes can be managed to sustain high levels of native vegetation richness for decades. Drawing from three years of research, this presentation will discuss specific heempark management techniques, explain how varying levels of management intensity impacts species richness, and posit how integrating landscape management into the design process is crucial to ensuring that designs remain beautiful and species-rich long after installation, as so many heemparks have successfully achieved.

Tuesday, October 24, 2023 | 3:00 - 4:15 PM ET

  • Keenan Porter is currently a landscape designer with Rhodeside & Harwell.

Native Plants in YOUR Landscape: Set it and Edit

(Non-professional)

Dan Segal

In the wild, plants primarily proliferate sexually from seed. As a consequence, even plants of the same species are genetically diverse. In nature, that diversity is a major driver of long-term balance and natural replacement. In the nursery however, where most plants have been propagated asexually from cuttings, divisions, or lab cloning, that genetic diversity is lost. In this lecture, native plant expert Dan Segal will reveal how seed-grown, genetically diverse plants behave at his nursery, and how the benefits he has observed can translate to your garden. He will also explain how to understand and incorporate ecological succession, the natural process that guides vegetational change over time. By understanding these foundational ecological principles, gardeners can guide nature instead of fight it, even at the smallest of scales.

Thursday, October 19, 2023 | 3:00 - 4:15 PM ET

  • Dan Segal has been working with native plants since 1990 (33 years).

Wild Residential: Accommodating Spontaneous Vegetation

(Non-Professional)

Larry Weaner, FAPLD

In nature, plants spend millenia evolving strategies to more efficiently procreate. In the garden, we arrest that procreation by weeding virtually every individual that we didn’t plant. Over the last 40 years Larry Weaner has learned to plan for and “edit” spontaneous vegetation within his designed landscapes. Much of these landscapes’ ecological value, reduced management requirements, and experiential dynamism have resulted from this approach, a skill that was largely honed on large properties. Here however, Larry will refocus on the small residential landscape, exploring the practical, ecological, and experiential benefits that loosening the vegetative reigns can provide…even where space is tight and neighbors are close.

Beyond Plant Lists:
Creating Year-Round, Robust Habitat for Wildlife in Home Gardens

(Non-Professional)

Shaun McCoshum, PhD

Creating wildlife habitat in gardens is most often described with plant lists, especially for birds and pollinators. Plants however, mostly feed wildlife and do not provide the appropriate places to shelter, reproduce, hydrate, and overwinter. Join us to learn more about creating beautiful gardens with plants and non-flower resources like logs, stones, and diverse soils. Shaun will also discuss how to incorporate selective ecological disturbances into annual garden maintenance, a very important habitat element that is often overlooked.
