3/18/17 - Liberate Your Home Landscape Plants, DE

With Larry Weaner

Saturday, March 18, 2017 11 am – 12 pm

Registration Link:

All too often we design our gardens and landscapes with static compositions of carefully placed and managed plants. But our approach can be more dynamic-and arguably more rewarding-by building upon ecological processes as well as plants' innate tendencies to reproduce and proliferate. Using examples from client projects and his property, Larry Weaner illustrates how this organic, give-and-take approach to design can result in low-maintenance, beautiful landscapes that marry human intent with the patterns and processes of nature.

Copies of Garden Revolution: How Our Landscapes Can Be a Source of Environmental Change, which Larry coauthored with Thomas Christopher, will be available for purchase and signing after the lecture.

Larry Weaner has been creating native landscapes since 1977. His firm, Larry Weaner Landscape Associates, has a nation-wide reputation for combining ecological restoration with fine garden design. The firm's work has received numerous awards and been featured in Garden Design, The American Gardener, and Landscape Architecture Magazine. Larry founded the New Directions in the American Landscape conference.

2/23/17 - Environmental Landscape Design, DE

With Jenna Webster

Five Thursdays: February 23 to March 23, 2017

Optional Project Evaluation: March 30, 2017

1 – 4 pm

Registration Link:

Ecologically sound landscapes require less maintenance, fewer inputs, and are adapted to local environmental conditions. Learn how to measure, inventory, and analyze a site; then make a conceptual design and planting plan using the "right plant, right place" approach. Broaden your design perspective, increase biodiversity in the landscape with native plants, decrease space dedicated to lawn, and create habitats that benefit insects, birds, and other fauna.

Jenna Webster is a designer with Larry Weaner Landscape Associates where she’s worked on meadow and habitat plans for public parks and preserves as well as landscape master plans for residential properties. She holds a Master of Science in Ecological Design from the Conway School.

2/11/17 - Wildflower Ecology: A Naturalist’s Perspective, Hockessin, DE

With Carol Gracie

Saturday, February 11, 2017, 11 am – 12 pm

Registration Link:

Our native woodland wildflowers are more than just a delight for the eye: they have adapted to their environment over millennia and play important roles in the ecology of their region. Join naturalist Carol Gracie and learn the fascinating life histories of spring ephemerals. Topics

include adaptations for early blooming, pollination and seed dispersal, and the latest scientific research on the ecology of these beautiful plants.

Copies of Carol's book, Spring Wildflowers of the Northeast: A Natural History, will be available for purchase and signing after the lecture.

Carol Gracie is retired from The New York Botanical Garden, where she worked in the Science

Division. She has since returned to her earlier interest in local flora and has co-authored, with

Steven Clemants, Wildflowers in the Field and Forest: A Field Guide to the Northeastern United States. Her latest book, Spring Wildflowers of the Northeast: A Natural History, was published by Princeton University Press in 2012. Carol is currently working on a book on the natural history of summer wildflowers.

Title: Secondary Pathogens of Stressed Trees and Shrubs

Description: Predisposing and inciting stresses, such as drought and insect defoliation, initiate the decline of trees and shrubs, leaving them vulnerable to attack from opportunistic pathogens in landscape and forest settings. Many of these pathogens have broad host ranges, tolerate a wide array of environmental conditions and are widespread on otherwise healthy trees and shrubs. Once critical resources are depleted, these pathogens can rapidly spread throughout the roots or canopy and are ultimately responsible for death.

Nurturing the Liberated Landscape
Larry Weaner

All too often we think of gardens and landscapes as static compositions of carefully placed and managed plants. But a more dynamic and rewarding approach takes advantage of the unique characteristics of plant species and communities, working with ecological processes, not against them. Learn how designer Larry Weaner utilizes the natural adaptations and reproductive abilities of plants to create engaging, ever-evolving landscapes that bring new meaning to partnering with nature. Using examples from his own property and from client projects, Larry will share how this give-and-take approach results in compelling, low-maintenance landscapes that free plants to perform according to their natural abilities and liberate people from having to cater to their landscapes’ every need.

The Art and Science of Growing Native Plants from Seed: Why, When, and How
Randi Eckel

As we incorporate more native plants into our landscapes, there are so many good reasons to use plants propagated from seed. But wild plants have evolved with a dizzying array of mechanisms, including chemical-induced dormancy and mandatory cold stratification, to ensure that their seeds disperse, persevere, and germinate at just the right time under natural conditions. These mechanisms are not in place to frustrate would-be plant propagators, but must be understood by gardeners to successfully grow native plants from seed. Come for a far-reaching discussion of the issues surrounding seed collection, procurement, and propagation, with information that will encourage the novice and challenge the professional alike.

How Native Plant Cultivars Affect Pollinators
Annie White

Initiatives to address pollinator decline are widespread and native plants are the preferred choice for pollinator habitat restoration. The growing demand for natives, coupled with a longstanding desire of horticulturalists for enhanced bloom, color, or other characteristics, has led to the increased selection and breeding of native cultivars. Although these cultivars are typically marketed for their ecological benefits, until now there have been no scientific studies to support or refute these claims. So are native cultivars as valuable in pollinator habitat gardens as the true native species? Annie White will help answer this question by sharing the results of four years of field data. Her research is groundbreaking and remarkable.

The Challenge of a Public Native Plant Garden: Maintenance, Interpretation and Compromise
Michael Hagen

The New York Botanical Garden’s new Native Plant Garden opened in 2013. Designed by Oehme van Sweden, it includes a diversity of microclimates on 3.5 acres of varied terrain with a planting plan of almost 100,000 native trees, shrubs, wildflowers, ferns, and grasses. Curator Michael Hagen will explain how this garden is successfully maintained, and their criteria for what constitutes “native” in species selection and the use of cultivars. This very public landscape presents native plants in a contemporary style, with an emphasis on aesthetics over recreating habitat. Michael will share his observations about how the public perceives and responds to the value of this native plant palette, along with ideas for inspiring others to “go native.”
