WHAT’S IN A NATIVAR?

BY CAROL BECKER

And what isn’t? Designers and pollinators are finding out.

FROM THE JULY 2019 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

Common buttonbush (Cephalanthus occidentalis) is a medium-sized shrub that is appealing in sunny areas of the landscape because of its glossy green leaves; unusual fragrant, round, spiky flowers; and rust-red fall color. It’s especially useful in wet areas and rain gardens where it absorbs excess water and even tolerates standing water. Hummingbirds and butterflies favor the plant for its nectar, and 24 species of birds seek it out for its small, round nuts that persist into winter. This native of the Midwest and East Coast is easily grown and little bothered by pests in the garden. Yet it is not commonly used in built landscapes. Although everything else about this shrub is right, its growth pattern and size are not. The straight species can be quite large at 12 feet high or more, and it has an annoying habit of sending branches in all directions, so it looks willy-nilly rather quickly if it’s not pruned regularly and often.

But here come Sputnik, Sugar Shack, and Fiber Optics, cultivars of buttonbush that represent a tamed C. occidentalis. Cultivars are plants produced by selective breeding or vegetative propagation to achieve better traits for the landscape. Fiber Optics is a species mutation discovered by an inventory employee in the bare-root fields of Bailey Nurseries, says the company’s public relations and communications specialist, Ryan McEnaney. Bailey trialed the plant, a process that takes several years, and brought it to market in 2017. It has a reliably smaller size at five to six feet high and a branching habit that keeps it compact and rounded, while retaining all the desired features of the straight species.

The Fiber Optics buttonbush is what is known as a nativar. The term is not scientific but has value to the industry in (more…)

Three firms discuss how their internship programs benefit both interns and staff.

From the June 2018 issue of Landscape Architecture Magazine.

With summertime come internships, those short stints of employment when students get the chance to enrich their academic experience with the practicalities of the real world. Of course, it’s an exciting time for interns, seeing how it all works for the first time. But how are offices reciprocally enriched by their internship programs? Once on board, how do interns fit into an office structure, and how do they affect day-to-day workflow? Three design offices explain their approach to taking on summer interns and discuss the impacts on office culture and resources.

Interviews have been edited and condensed. (more…)

A pilot study suggests playground equipment can provide social and emotional benefits for children with sensory disorders.

FROM THE JUNE 2018 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

Lucy Miller lost her sight when she was 16 and, in 1970, underwent one of the nation’s first corneal transplants. A procession of specialists flitted in and out of her recovery room—doctors, nurses, residents, fellows—but she recalls thinking that only the occupational therapist was interested in her as a person.

Shortly after her release from the hospital, she abandoned her plans to go to law school and headed to graduate school at Boston University to study occupational therapy. It wasn’t only the care and attention of her former occupational therapist who had led her to this decision. In the hospital, over several months when her eyes were surgically detached from her skull, she noticed her other senses had grown sharper. She wondered why, neurologically, this had happened, and was determined to find out. So, in her early twenties, still in graduate school, she embarked on a summer mentorship at the Torrance, California, clinic of Jean Ayers, the originator of a then-emerging field exploring the relationship between the sensory processing dysfunction and the behavior of children with disabilities.

Nearly half a century later, Miller, who is the clinical director of the STAR Institute for Sensory Processing Disorder just south of Denver, has become one of the nation’s preeminent scholars on sensory processing disorder (SPD). This term is used to describe difficulty with “one or more of the sensory processes that occur along the neurological pathway, from detecting stimulation to regulating the input and output, to interpreting the sensations correctly, to responding accurately, and finally, to turning the sensory input into meaningful responses,” as she explained in her 2014 book, (more…)

Traction believes landscape architecture is for the people, not just the elite.

FROM THE MAY 2018 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

In 2016, as a student at the University of Washington, Coco Alarcón won the ASLA Student Residential Design Award of Excellence for his project to improve public health by creating food gardens in a soggy, stressed neighborhood in Iquitos, Peru. He was also named a National Olmsted Scholar finalist that same year. Since then, Alarcón, who is Peruvian, has been working with a multidisciplinary collective he co-founded called Traction (formerly the Informal Urban Communities Initiative) to try to bring his ideas to fruition. Using research, community outreach, activism, and educational workshops, Traction works with people from communities where resources are scarce to create new social and physical infrastructure that promotes health, safety, and beauty for residents. LAM recently caught up with Alarcón to find out how his group’s work has progressed toward giving people, as he hopes, the motivation they need to transform their environments into equitable, healthy places.

This interview has been edited and condensed.

What are you working on now?
One of our projects is to design and construct a landscape architecture intervention in a slum community and measure the impacts on human, ecological, and environmental health. For example, we are documenting changes in human microbiome, water quality, mental health, and biodiversity of birds and amphibians—among other measurements—in the community to understand the effects of a productive community garden.

Another project focuses on the collection of literature, local experiences, and interviews with experts from different disciplines to understand the role that landscape architecture has on the pandemic of vector-borne diseases related to the Aedes aegypti mosquito, including Zika, dengue, and chikungunya.

The McHarg Center—a new research initiative that will study the intersection of urbanism and ecology—is dedicated to studying how “urban growth and all of its related infrastructure can relate better and be better tuned to ecosystems,” says Richard Weller, ASLA, chair of the landscape architecture department at the University of Pennsylvania. The center is awaiting its formal launch next year with an exhibition, book, and conference timed to the 50th anniversary of Ian McHarg’s seminal book Design with Nature. In the meantime, the center, housed within PennDesign, has invited Jeff Goodell, the author of The Water Will Come: Rising Seas, Sinking Cities, and the Remaking of the Civilized World (Little, Brown, and Company, 2017), to visit for an inaugural lecture on March 29, at 6:00 p.m. in the lower gallery of Meyerson Hall.

In the spirit of McHarg’s research, Weller envisions the McHarg Center as an intensely multidisciplinary place. “When he completely overhauled the curriculum at Penn, he stacked the building with scientists,” Weller says. Likewise, Penn’s McHarg Center will invite scientists, designers, engineers, and public policy experts into an (more…)
