Smithsonian Gardens’ Campus-Wide Habitat Exhibition

Sign of the Dragonfly exhibit

The Smithsonian Gardens staff have installed a campus-wide exhibition with a single theme: habitat. From now until December 2020, fourteen exhibits across the Smithsonian campus in Washington DC, both inside and outside, will be available for the public to view.

This Habitat exhibition illustrates diverse stories about habitats and the plants, animals, and humans that exist within those habitats. The message is simple: Protecting habits protects life. This theme was selected for its relevance to the Smithsonian Grand Challenge of “understanding and sustaining a biodiverse planet” and to the Smithsonian Gardens’ mission to “inform on the roles people and plants play in our cultural and natural worlds.”

Dead Wood Is Life exhibit

Three key messages are woven into all the exhibits: habitats are homes, habitats are interconnected and fragile, and habitats need to be protected. Informative signage at each exhibit explains concepts such as indicator, keystone, and foundation species; symbiotic relationships; and ecosystems.

During the exhibition’s run, Smithsonian Gardens staff will host a variety of habitat-related events and educational programs. A map showing the location of the exhibits is on the Smithsonian Gardens website.

U.S. Botanic Garden’s New “Gardens Across America” Exhibit

Franklin Park Conservatory and Botanical Gardens’ Flamingo Display

The U.S. Botanic Garden (USBG) has a new exhibit called Gardens Across America. The exhibit showcases 21 public gardens through vignettes created by each garden displaying plants and items illustrating the gardens’ stories. The displays were chosen from a call for entries to all gardens across the country. The vignettes are located throughout the outdoor area of the USBG in Washington DC and range in size and scope. For example, Fort Worth Botanic Gardens is showcasing its begonia mascot; Pittsburgh Botanic Garden is demonstrating cleaning mine water and creating new gardens; Tucson Botanical Gardens has cacti and agaves in its barrio garden; Atlanta Botanical Gardens has carnivorous pitcher plants; and the State Botanic Garden of Georgia has native pollinator plants. The exhibit demonstrates the diversity and beauty of the more than 600 public gardens in the United States. Throughout the exhibit run, which ends on October 1, the USBG will offer programs, workshops, lectures, and tours related to the exhibit.

Tucson Botanical Gardens’ Barrio Garden

The USBG is open to the public, free of charge, every day of the year from 10:00 am to 5:00 pm with outdoor gardens having extended hours until 7:00 pm from Memorial Day through Labor Day.

Pittsburgh Botanic Garden’s Water Filtering System

Relax in DC’s Renovated and Sustainable Bartholdi Park

The U.S. Botanic Garden (USBG) has completed the renovation of Bartholdi Park. The new garden is a showcase of sustainable gardening. Created in 1932, Bartholdi Park has served as a demonstration garden for more than 80 years. In 2016, a complete renovation started that also provided the opportunity to increase accessibility, showcase the Sustainable SITES Initiative principles in action, and demonstrate USBG’s commitment to sustainability.

Some of the changes will be noticeable to visitors. For example, most of the plants are native to the mid-Atlantic region. There is an expanded collection of edible plants in permanent and seasonal plantings in a new kitchen garden. Some of the large trees and shrubs were retained while others were placed in other locations in DC. There is more signage and more places to sit and relax. The tables and chairs were made from white oaks that had fallen naturally during a storm. There is a bike rack, additional lamps/lighting, and a water fountain. There will be outside activities such as yoga and nature-in-motion walks. Not so obvious to visitors are structural changes such as using permeable paving and rain gardens to capture rainfall, diverting runoff from D.C.’s combined sewer system. The original soil was saved and then added back with additional compost. Flagstones from previous pathways were salvaged to create new paths.

Bartholdi Park has achieved the SITES gold certification for its sustainability strategies. It is the first project in Washington, DC, to be certified under SITES Version 2. Sites is a comprehensive system for designing, developing, and maintaining sustainable land. The Park serves as a model for communities interested in sustainable gardening landscapes that are accessible and enjoyable by the public.

The story of the renovated Park is shared through new signage in the Park. A new Field Journal, an interactive booklet for young visitors, can be picked up free at the U.S. Botanic Garden’s information desk. Tours of the Park and other activities can be found at www.usbg.gov/programs.

The U.S. Botanic Garden is open to the public, free of charge, every day of the year from 10:00 am to 5:00 pm. The conservatory is at 100 Maryland Avenue SW on the southwest side of the U.S. Capitol. The Bartholdi Park is across the street. All of these photos are courtesy of USBG.

School’s Out: Visit the Newly Renovated Children’s Garden at U.S. Botanic Garden

Now that school is out, take your kids to the newly renovated Children’s Garden at the U.S. Botanic Garden in Washington DC. The Children’s Garden is in an open air space in the center of the glass greenhouses. Several new structures have been installed including a large metal platform discovery station with steps for children to walk up to a covered lookout station. As they ascend the platforms, they will see interactive panels filled with botanical materials.

The garden also has a new digging area for children to use child-sized tools and to learn about composting. There are raised beds for them to plant and water at their level. There is a series of fabric and metal leaf shapes at varying heights to provide shade and interest and dandelion metal sculptures with steel “seeds” that sway in the breeze. New child-size seats resemble oversize watering cans and toadstools. A new metal arbor has replaced the old vine tunnel, soon to be covered with kiwi vines.

The U.S. Botanic Garden (USBG) is open to the public free of charge every day of the year from 10:00 am to 5:00 pm. The Children’s Garden, which is actually outside, is open seasonally, usually May to October. The USBG has many events for children and adults every month, including seasonal displays. Check out their website for activities at http://www.usbg.gov.

usbg-holiday-show-lincoln-memorial-and-washington-monumentThis year’s annual U.S. Botanic Garden holiday exhibit, Season’s Greenings: National Parks and Historic Places, will open Thanksgiving Day, November 24, 2016 and run through January 2, 2017.

In this year’s model train show, the trains will chug around, below, through, and above re-creations of iconic national parks and sites in the National Register of Historic Places. See the Grand Canyon, the Gateway Arch, Old Faithful Inn and Geyser, Mount Vernon, Mount Rushmore, a 7-foot-tall Statue of Liberty, and many more representing 48 different national parks and historic sites, all made from plants and other natural materials.

The West Gallery will house one of the largest indoor trees in Washington, DC, covered with ornaments celebrating national parks, and the Garden Court will welcome back model landmarks from the nation’s capital including favorites like the U.S. Capitol, the Washington Monument, the Lincoln Memorial, and more – all also made from plant materials.

Garden Conservancy’s Open Days Program Features Three Private Gardens in Washington DC, October 16

gc_web_logoOn Sunday, October 16th, visit three private gardens in Washington, DC, open to the public through the Garden Conservancy’s Open Days Program, 10 a.m. to 4 p.m. Admission to each garden is $7; children 12 and under are free. Open Days are rain or shine, and no reservations are required. Visit www.opendaysprogram.org  or call 888-842-2442 for more information. Gardens featured include:

Sessums + Biles Garden, 5081 Lowell Street, NW (near American University)

The Sessums + Biles Garden is a horticultural treasure where sustainability and design embrace. The client, a passionate gardener bored with traditional “green on green” landscapes, commissioned a garden with careful consideration to all seasons and where plant form, texture, and color are of equal importance. The result is a dynamic, ever-changing tapestry of predominantly native trees, shrubs, perennials, and groundcovers. Sweeping paths, walls, terraces, and a water feature form the backbone of this unique garden. No herbicides or fertilizers are used, and pesticide use is strictly limited to the aging stand of hemlocks. The site is not irrigated, site water is reclaimed, and all garden material is composted on site. The garden is also a Certified Wildlife Habitat through the National Wildlife Federation and the client is physically involved in all aspects of the garden’s maintenance.

The Barbara Downs Garden, 3321 P Street, NW

Located in Georgetown, this town garden exudes the spirit of Japan, a favorite travel spot of its owner. A dry streambed of randomly placed stones descends from the elevated rear of the garden and meanders to the house, terminating in a circular arrangement of stones that mimic a pool. The centerpiece of the garden, a sculptured millstone-shaped pink granite fountain surrounded by lavender plantain lily (Hosta x ‘Honeybells’) bubbles with life. Framed by crepe myrtle ‘Natchez’ (Lagerstroemia indica ‘Natchez’), the terrace of Stoneyhurst flagstone provides a reflective escape in this hidden urban garden.

The Nancy Gray Pyne Garden (street address will be given at other locations)

A journey through this secret garden in the heart of Georgetown takes the visitor up a series of formal terraced gardens and past a number of outbuildings that include a library, two greenhouses, and a freestanding theater. It culminates in a decorative walled vegetable garden designed and planted by Washington Post garden writer, Adrian Higgins. The garden had been assembled over the course of a century or more, but it was given its character in the 1930s as one of the major Washington projects of a pioneering landscape architect named Rose Greely. The main terrace is a walled garden perched above the house. Its most animated feature, a geometric fountain, is aligned with both the rear entrance of the house and, at right angles to it, a rectangular lawn framed by a path and boxwood plantings. The upper garden functions as its own formal garden of shrubs and small trees, as well as an entrance for the theater, known as the playhouse, and the larger greenhouse (and potting shed). The upper garden is also a place of paths. One leads to a parking lot at the end of an alley. Another passes a long boxwood walk that leads past a fenced swimming pool, which was once an ornamental garden and, later, a tennis court. The vegetable garden is bounded by more brick walls and by the back of the garage and a cedar fence. The space, sixty feet by thirty feet, also contains the second greenhouse built by Nancy Gray’s husband, Gordon Gray, who was a passionate orchid grower.

In addition, at the garden of Nancy Gray Pyne, bring your questions throughout the day for Andrea Filippone and Eric T. Fleisher of the New York-based firm, F2 Environmental Design. Andrea Filippone is a boxwood expert who has advised Mrs. Pyne on boxwood selections in her garden, and Eric T. Fleisher is the organic guru in the firm, who believes that the basis of all successful gardening is an understanding and nurturing of the soil biosphere.

The Garden Conservancy created the Open Days program in 1995 as a means of introducing the public to gardening, providing easy access to outstanding examples of design and horticultural practice, and proving that exceptional American gardens are still being created. Its mission to share American gardens with the public is achieved each season, through the work of hundreds of private garden hosts and volunteers nationwide. Digging Deeper, a new series of Open Days programming, is designed to offer a deeper look into the gardening world through immersive experiences with artists, designers, gardeners, authors and other creative professionals. The Open Days program is America’s only national private garden-visiting program. For information and a complete schedule of Open Days visit the Garden Conservancy online at www.opendaysprogram.org.

Corpse Flower to Bloom This Week at U.S. Botanic Garden, Washington DC

Peak Bloom in 2013

Peak Bloom in 2013

Take your kids to see the corpse flower! The plant went on display at the United States Botanic Garden (USBG) Conservatory on July 22 and should be at peak bloom between this Thursday and Sunday, July 28-31. Once fully open, it usually remains in bloom for 24 to 48 hours and then quickly collapses. The plant is famous for its large size and pungent odor — it emits a putrid scent while in bloom to attract pollinators such as carrion beetles and flies. Native to the tropical rain forests of Indonesia, Amorphophallus titanum can take several years to several decades to store enough energy to bloom so there are very limited times that the public can see the bloom in the United States. The USBG last displayed a blooming corpse flower in 2013. The USBG is open to public free of charge every day of the year from 10:00 am to 5:00 pm. However, the Conservatory will stay open until 8:00 pm while the corpse flower is on display and will remain open until 11:00 during peak bloom (forget the kids, think of this as an unusual “date”). The USBG Conservatory is at 100 Maryland Avenue SW; (202) 225-8333.

Starting Friday July 15, she will teach how to grow hardy annuals (flowers) such as bells of Ireland, snapdragons, and sweet peas. Each Friday for 10 weeks (1 week for each chapter), she will show a short video and answer questions. There is no fee and it is not required to have the book although it will certainly be beneficial to read along. If you are like me and work on Fridays, you can sign up at her web site to have the weekly links sent to your e-mail or you can visit the web site any time. Lisa has been a cut flower farmer since 1998 and has built a very successful business. She produces 10,000 stems each week during the growing season on 1 ½ acres. She has written several books, sells seeds and supplies, hosts workshops, and gives presentations across the county.
