Visit Demonstration Gardens for Education and Inspiration

In the summer I like to visit demonstration gardens to see how well the plants and vegetables performed in this area. Demonstration gardens are a great way to learn what works in the Washington DC metro area and how to manage our local issues, such as deer and rabbits. Each county that has a Master Gardener program usually has at least one demonstration garden, managed by the volunteer Master Gardeners. These are open to the public and free. To find such a garden, call your local county Master Gardener program representative (your local extension agent). Some have several to showcase various environmental conditions and some use the garden as a place to teach or host workshops.

In Northern Virginia, the Master Gardeners of Northern Virginia (Arlington and Alexandria) now have eight demonstration gardens. They recently added Buddie Ford Nature Center Garden. The Prince William County Master Gardeners manage a very large Teaching Garden at St. Benedict Monastery, 9535 Linton Hall Road, Bristow. Within this property are mini gardens to illustrate certain conditions or issues, such as a deer resistant garden, shade garden, vegetable garden, and pollinator garden. The Loudoun County Master Gardeners uses Ida Lee Park on Ida Lee Park Drive, Leesburg, as a teaching garden.

In Maryland, the Montgomery County Master Gardeners manage six demonstration gardens. The Prince Georges County Master Gardeners have demonstration gardens at their headquarters at 6707 Groveton Drive, Clinton.

In DC there is the Washington Youth Garden, a program of the Friends of the National Arboretum, with support from the U.S. National Arboretum.  This is located on the Arboretum grounds.

Some plant societies such as the National Capital Dahlia Society have demonstration gardens specific to their plant of interest. Contact the society directly to see if they have one. The National Capital Dahlia Society has the Nordahl Exhibition Garden for displaying dahlias at the Agricultural History Park in Derwood, MD. Plant NoVA Natives has a list of demonstration gardens that feature native plants on their site.

If you know of any that I have not listed here, please contact me and let me know.

This Summer Visit Public Gardens

Summer is the time for traveling, exploring, and spending time with family. Thinking of where to go? Consider public gardens and arboreta. Many of these are historic places as well, great for teaching your kids. On my website, pegplant.com, I list local public gardens as well as gardening books written specifically for the Washington DC metro area. Several of these books, copied and pasted below, are resources listing botanical, public, or historic gardens in eastern states.

Visit the Philadelphia Flower Show on Opening Day!

This year the theme for the annual Philadelphia Flower Show is Riviera Holiday. In the past I have written articles about the show and the local nurseries and private organizations that host chartered bus trips. Taking a luxury bus is a great way to attend, no need to worry about traffic and parking. This year, there is a new trip so you can attend the first day, Saturday, February 29 (the show runs until March 8).

Teri Speight, owner of garden website Cottage In the Court, has reserved a bus departing from the lower parking lot of the District Heights Municipal Building, District Heights, MD. The bus departs at 8:00 am and returns by 9:00 pm. A native Washingtonian, Teri is a garden blogger, garden visionary, and a great garden speaker. For more information, contact Teri directly. The reservations deadline is Tuesday, January 14, 2020. Call at (301) 785-7507 or e-mail at teri@cottageinthecourt.com.

Each year the Philadelphia Flower show has a different theme and this year Riviera Holiday is inspired by the world’s exotic Mediterranean gardens. What a great break this will be from our cold, dreary winter! According to the flower show’s website, “groves of citrus trees lead the way providing a lush dramatic promenade to the sunshine drenched landscape ahead. Breathe in fragrant waves of lavender inspired by the terraced gardens of Monaco. Drifts of purple and white spiked salvias, specimen succulents, and an intoxicating variety of scented geraniums, roses, rosemary, and sage create a stunning mosaic that is at once picturesque and charming.”

Who could resist?

Three Heat-Tolerant, Pollinator-Attracting, Deer-Resistant Perennials

We are having a hot, dry streak now which really separates the weak from the strong in the garden. Now is a good time to see which plant is tolerating this weather well in other people’s garden so you can copy for your own garden.

On one particularly hot day this past weekend I was downtown visiting the Smithsonian museums. I spent a lot time in the Pollinator Garden, next to the National Museum of Natural History. This is a 400 x 40 feet area on the east side of the museum at 9th Street between Constitution Avenue and the Mall. The Pollinator Garden is managed by Smithsonian Gardens staff and is a wonderful place to relax and watch the butterflies.

I noticed several plants that were tolerating the heat well, that is, they were in full sun and not covered in powdery mildew.  As expected, they were definitely attracting bees and butterflies. These seemed worthy of copying in my garden. When I got home I looked them up and learned that they are rabbit and deer resistant as well as being full sun, drought-tolerant perennials. This is not to say there weren’t other worthy notables in the Pollinator Garden but these are definitely plants to add to my collection next year!

Wild Petunia

Although this plant is called wild petunia (Ruellia numilis), it is not related to petunias. These plants have lavender blue flowers that bloom from summer to fall. They are low growing with a trailing habit, reaching about a foot tall. They can serve as a groundcover and be used as a spiller in a container.

Allium ‘Millenium’

‘Millenium’ is a member of the onion family (Allium) grown for its ornamental, purple globe flowers. The plants grow to 1 to 1 ½ feet tall, providing a strong vertical interest.  They are great in the garden and can be used in containers as thrillers. After the flowers fade and die, the globe structure becomes tan and remains for a while, which also provides interest.

Walker’s Low catmint (Nepeta) is a member of the mint family, so it has gray green aromatic foliage. In the summer, the plant has small, lavender blue flowers, but each stalk has so many that sometimes the plant seems covered in a purple haze. The plants are low growing, about a 1 to 2 feet tall, and used as a groundcover or small shrub.

Cooperative Extension Offices Can Help You With Your Garden

The Cooperative Extension System is a nationwide, non-credit educational network designed to help individuals with many activities, one of which is gardening. It is actually managed on a federal level within the U.S. Department of Agriculture’s National Institute of Food and Agriculture (NIFA). NIFA provides federal funding to the system. Each state and territory has a state office at its land grant university. The state office then manages county extension offices. For gardening assistance, you will want to reach out to your county extension agent and depending on the office, you can:

  • Get your soil tested free
  • Find out what is wrong with your plant
  • Get plant/pest information
  • Obtain publications on specific topics
  • Attend lectures and workshops sponsored by them
  • Get involved in the Master Gardener Program

In Maryland, the University of Maryland manages the Maryland Cooperative Extension. For gardening assistance contact your county extension agent or the Home and Garden Information Center, 12005 Homewood Road, Ellicott City, MD 21042, (410) 531-5556.

In Virginia, the Virginia Tech University manages the Virginia Cooperative Extension program. Headquarters is at Virginia Cooperative Extension, 101 Hutcheson Hall, 250 Drillfield Drive, Virginia Tech, Blacksburg, VA 24061-0327; (540) 231-9347.  Contact your Virginia county extension agent for gardening assistance.

In DC, the University of the District of Columbia manages the Cooperative Extension Service through its Center for Urban Agriculture and Gardening Education. This is part of the College of Agriculture, Urban Sustainability and Environmental Sciences at 4200 Connecticut Avenue, NW, Washington DC 20008, (202) 274-5000. They offer classes, workshops and the Master Gardener program.

Bunny Mellon’s Gardens at Oak Spring Garden Foundation

The Formal Garden is enclosed by buildings and white washed stone walls

This past April, I was fortunate to visit the Oak Spring Garden Foundation with one of my gardening clubs. I say fortunate because the estate is not open to the public yet. They have just started to open to gardening clubs by lottery, with a limit of three clubs per year. Because they could only accommodate 30 people and very few cars, we carpooled on a misty Friday morning to Upperville, Virginia. The short trip put us in horse country, very remote with no other property in sight.

Bunny and Paul Mellon

The Oak Spring Garden Foundation was established by Rachel Mellon, known as “Bunny,” before she died in 2014 at the age of 103. Bunny was born to a wealthy family in New Jersey. Her grandfather was the inventor of Listerine and founder of Lambert Pharmacal Company. She married Stacy Barcroft Lloyd Jr. in 1932, divorced him in 1948, and married Paul Mellon. Paul, a recent widower and son of Pittsburgh financier Andrew W. Mellon, had already purchased the estate then known as Rokeby.

Espaliered fruit tree

Bunny and Paul renamed the 4,000-acre property Oak Spring. This was a working farm, with cattle raising, thoroughbred horse breeding and racing, fox hunting, and gardening. They also owned residences in Cape Cod and Nantucket, Massachusetts; New York City; Washington, DC; and Antigua. Together they were very interested in collecting artwork, much of which has now been donated to museums. Bunny was a keen gardener and landscape designer. She was especially interested in the art of pruning and topiary. Bunny was friends with Jack and Jacqueline Kennedy and redesigned the White House Rose Garden and redesigned the White House East Garden that was later dedicated to and renamed the Jacqueline Kennedy Garden. She actually designed other gardens as well including the gardens of her other properties. Bunny liked all things French and was an avid collector of horticultural books and manuscripts. She amassed a collection of 16,000 books, manuscripts, and botanical artwork now housed in a singular building on the property. Today, this library is open by appointment for researchers and scholars but the Foundation is digitizing some of the collection. Several books have been written about Bunny. Paul, who predeceased Bunny at age 91 in 1999, wrote an autobiography.

Formal Gardens

Part of our tour was to see the Oak Spring Garden Library but we were not able because of the humid weather. Angie Ritterpusch welcomed us and although she showed us other parts of the estate, this article is solely about the gardens.

We gathered under the famed crabapple allee, with our umbrellas and boots. The allee, made up of Mary Potter crabapples trained to arch over and create a tunnel, connected the Formal Garden with the Lord & Burnham Victorian-style greenhouse. Horticulturist Judy Zatsick led us through a large wooden gate into the walled, formal garden (see video below). It was like stepping into a forgotten secret garden that flourished during war-torn France. Evidence of time passed was reflected in the white washed walls, the lichen encrusted trees, and the old brick paths. Bunny’s garden was restrained and purposeful. The half-acre was a composite of many, small garden beds enclosed by stone walls and small buildings, such as the basket house and guest houses. The land was laid out in three levels ascending (from the gate) to the back of the house.

We immediately walked towards the backside of the house and on to the Sunday Kitchen Patio, which afforded us the view of the Formal Garden and the greenhouse in the distance. From there we could see the three levels and the central axis path that went directly from the house to the gate as well as a parallel path to the left side of the enclosed garden. Because it was spring, pansies, tulips, aquilegia, viola, and daffodils were blooming. The fruit trees had greened up and there were large hostas, untouched by deer. You would think that with their wealth the garden would be ostentatious but it wasn’t, it was relatively formal because of its geometric design and symmetry. However, the plantings made it simple and delightful. The garden encapsulated Bunny’s motto that “nothing should be noticed and nothing should be obvious.”

Sunday Kitchen Patio

The Sunday Kitchen Patio was a brick-laid patio directly off the house and kitchen. There was a small dogwood tree and seating area with a narrow bed of irises. From there we stepped on an old circular millstone down to the next level, the Upper Terrace. The Upper Terrace was paved with fieldstone so old that plants grew in the cracks. There was a small White Garden and a Rose Garden off to the side.

Square Garden in foreground with Upper Terrace in background

Using the main axis, we descended down stairs to the Middle Terrace. The paths were paved with fieldstone. The Square Garden on the left was a square patch of lawn. The Tea Garden and Butterfly Garden were on the right. The Tea Garden was full of herbs for making tea and the Butterfly Garden had butterfly shapes in the ground with plants to color the wings. Descending down stairs again was the Lower Terrace with gravel paths. On the left and right were large vegetable and herb gardens with a wishing well. Throughout the formal garden were espaliered fruit trees on the walls, cordon-style fruit trees to border the small gardens, a few clipped trees as well as large old trees.

East Vegetable Garden with Croquet Lawn on right

On the perimeter were more garden spaces such as the croquet lawn, pantry garden, and shade bed. This is the type of garden where you could spend a lifetime exploring and enjoying each small space, differentiated by plants, season, and light. Bunny’s design motto was that “Nothing should stand out. It all should give the feeling of calm. When you go away, you should remember only the peace.”

Oak Spring Garden Foundation

Bunny established the Oak Spring Garden Foundation so her library, gardens, and home would be a resource for those who love horticulture. The vision is to host scholars, writers, artists, and interns to not only learn about horticulture but also to learn from her library of over 16,000 original manuscripts and books.

View of South Vegetable Garden from Basket House

The Foundation also hopes to serve as a site for academic conferences. The Foundation mission is to support and inspire fresh thinking and bold action on the history and future of plants, including the art and culture of plants, gardens, and landscapes. Access to the gardens and library is by appointment only.  In 2020, the Foundation plans to open the gardens to the public for Virginia Historic Garden Week, which takes place in April/May.

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.
