Intensive Course Session 3 of 7 | The Open Landscape: Meadows, Old Fields, & Shrublands (Summer 2025)

Professional Virtual Intensive Course

Instructor: Larry Weaner, FAPLD

Wildflower meadows and native grasslands are in high demand, but effective protocols for successfully achieving them are in short supply. Here we will delve into the nitty gritty of meadow design: site analysis, species selection, seed mix formulation, live plant inclusion, planting and management. The inclusion of shrub thickets and drifts will also be covered, including the arrangement of clonal vs. clump forming species, and the use of shrublands as ecological and visual “connective tissue” between meadow and woods.

Professional Virtual Intensive Course

Instructor: Ian Caton

In this session, native plant authority Ian Caton will examine plants of the open landscape that exemplify the ecological characteristics described by Larry Weaner in previous sessions. His presentation will span the successional period from herbaceous meadow, to mixed woody/ herbaceous old field, to the ecologically important but often neglected clonal shrub thicket. He will also present a group of “workhorse” native species for the sunlit landscape that combine reliability and weed suppression with attractive aesthetic character.

Intensive Course Session 5 of 7 | The Canopied Landscape: Woodlands, Edges, & Hedgerows (Summer 2025)

Professional Virtual Intensive Course

Instructor: Larry Weaner, FAPLD

An ecology-based approach to woodland design is more like guiding a vegetative process than implementing a static planting plan. Guided succession can foster the orderly transformation from an open field to a multi-tiered forest through planting, managed natural recruitment, or a combination of the two. Under existing canopy, where few herbaceous species can be established through direct seeding, we will discuss the planting of small “seed source colonies,” and management strategies to encourage their proliferation into the larger landscape. Management techniques that are unique to woodlands including selective height cutting, sunlight manipulation, and assisted seed dispersal, will also be described in detail.

Registration is open and the recording is viewable for 3 months after the live session date.

Professional Virtual Intensive Course

Instructor: Ian Caton

In this session, native plant authority Ian Caton will examine plants of the canopied landscape that exemplify the ecological characteristics described by Larry Weaner in previous sessions. His presentation will include plants found at all of the woodland’s vertical layers, from canopy to understory. He will also discuss their specific abilities to integrate with the unique colonization strategies inherent in woodland development and enhancement. Finally, Ian will present a group of “workhorse” native species for the woodland, including those that combine reliability with desirable aesthetic characteristics.

Intensive Course Session 7 of 7: The Artistic Overlay: Making “Wild” Legible (Summer 2025)

Professional Virtual Intensive Course

Instructor: Larry Weaner, FAPLD

Ecological design need not be a bitter aesthetic pill that our clients must swallow to do the right thing. The order inherent in our wild native landscapes is widely considered beautiful. By translating that ecology-based order into the aesthetically-based language of fine garden design, the results can be much more universally embraced by our clients. In addition, Larry will illustrate how highly gardenesque - and even formal - elements can gracefully interact and intermingle with wilder woodland, shrubland, and meadow compositions. This approach can result in landscapes that are both ecologically productive and visually pleasing to clients with a variety of aesthetic preferences.

Ecology-based Design and Organic Practice at Glenstone Museum, Potomac, MD | In-person

The landscape at Glenstone, a newly-constructed, contemporary art museum in Potomac, Maryland, received the ASLA Honor Award in 2019. The property contains 90 acres of planted meadows, shrub thickets, and woodland glades that stretch from the property borders to the museum buildings. This organically planted and maintained landscape illustrates how landscape architects (Peter Walker Partners), native plant consultants (Larry Weaner Landscape Associates), and an in-house management team can collaborate in the service of ecology, art, and a stimulating visitor experience. Our day will combine classroom instruction with a heavy dose of field observation to illustrate how this landscape went from landscape plans to vibrant reality.

Native Perennials: Flower Border or Functional Ground Layer (Spring Virtual Series)

Native Perennials: Flower Border or Functional Ground Layer (Spring Virtual Series)

Larry Weaner, FAPLD

Perennials have long been planted for the beauty of their flowers, but in the wild they are a functioning part of virtually every ecological system. Their roots hold soil in place. Their seeds provide food for birds. Their flowers provide crucial nectar for pollinators while their stems and leaves host insect eggs (including declining Monarch butterflies). Finally, when planted as a dense ground layer, they can reduce the most time-consuming aspect of garden maintenance....weeding. In this presentation you will learn how to use seed and live plants to create perennial compositions that enhance the aesthetic, practical, and ecological character of any landscape.

Lawn to Meadow: Transition with a “Light Touch” (Spring Virtual Series)

Lawn to Meadow: Transition with a “Light Touch” (Spring Virtual Series)

Larry Weaner, FAPLD and Sara Weaner Cooper

No chemical use, no hauling, no digging, no smothering - no early-stage ugly phase. 

Sounds too good to be true.

Yet by gradually applying a series of light touch actions, you can achieve this organic transition without breaking your back, sparking ecological angst, or infuriating your neighbors. These actions can include timed mowing, selective height cutting, pH manipulation, and organic herbicide application.

In this session, Sara will discuss her lawn to meadow conversion (featured in The New York Times, 2024), including 2025 updates and plans, illustrating a homeowner’s perspective. Larry will explore case studies exemplifying the technical underpinnings behind this approach, from a landscape designer's perspective. This brains over brawn approach can transform the experience of creating residential meadows from daunting to uplifting.

Breaking the Grass Ceiling (Part Two): A Historic Cemetery Reckons with its Lawn Legacy (Spring Virtual Series)

Sara Evans and Jenna Webster

Rural cemeteries were among the first public landscapes in America to adopt expansive formal lawns, a legacy with far-reaching ecological, social, and financial consequences. Today, in the face of the climate crisis, The Green-Wood Cemetery in Brooklyn is working to adopt compelling alternatives, from less resource-intensive grass species to testing strategies for low native meadows. Learn the benefits and challenges of these approaches, understand what it takes to steward these dynamic plantings in a cultural landscape, and see how they could have applications beyond cemeteries.

Breaking the Grass Ceiling (Part 1): Native Lawns and Low Growing Meadows (Spring Virtual Series)

Dave Kaplow

How do we create true native habitat that is compatible with an urban and suburban environment? This lecture focuses on meadow/lawn hybrids, and how they can be used to create natural areas that are also accessible for frequent human use. Dave will emphasize the use of both cool and warm season grasses as the foundational species, as well as the broad leaf perennials that can visually and ecologically complement them. Illustrated applications will  range from native lawn on residential properties, to the open areas surrounding business plazas and shopping areas, to the fields and meadows of public parks.
