We’re bringing our month of wedding-themed #ThrowbackThursdays to a close with tips for caring for roses at home from Smithsonian Gardens horticulturist Shelley Gaskins. Shelley manages the Kathrine Dulin Folger Rose Garden next to the Smithsonian Castle.
June is one of the most popular months for weddings, and it’s also National Rose Month! Roses are a traditional and elegant flower choice for wedding bouquets and decorations. Did you know that Tricia Nixon was married in the White House Rose Garden in June of 1971? The White House Historical Association has a new exhibit exploring the Rose Garden during the Kennedy administration opening on July 16th. “The Kennedy Rose Garden: Traditionally American” features a few photographs and letters from the Archives of American Gardens. Did you choose roses for your wedding? Share your story in the comments!
Rose Tip #1: Do your research! Roses are rated on several characteristics. Choosing roses that are rated as resistant to fungal diseases such as black spot and powdery mildew should top your list.
Rose Tip #2: Roses require at least 6 hours of full sun (preferably in the morning), a well-drained and nutrient-rich soil, and moderate amounts of water. Water should only be applied directly to the root zone, not to the leaf surface. Adequate sunlight and water will help decrease the spread and incidence of fungal diseases.
Rose Tip #3: When pruning roses in early spring, prune with the understanding that opening up the center of the plant allows for light penetration and air circulation. Allowing light and air into the center of the plant will create an environment that is less favorable to fungal diseases. Be sure to clean the edge of your pruners with alcohol to avoid spreading viruses.
Rose Tip #4: Eliminating dead, dying and diseased plants and plant parts from your garden will help to keep your garden healthy. This includes cleaning up potentially diseased rose leaves that have fallen from the plant. Fungal spores can overwinter and return to the plant from the fallen leaves.
Rose Tip #5: Not all bugs are bad! get to know the insects that visit your garden. Find out which insects truly pose a threat to the health of your plants (pests). Find out if the pest has any natural predators (beneficial insects). A healthy garden should have both. If necessary, you can introduce mail-order beneficial insects into your garden.
Rose Tip #6: Beneficial insects are often beneficial only at certain stages in their life cycle. For example, the syrphid fly only feeds on prey while they’re in their larval stage. Adult syrphids don’t eat other insects, they eat nectar and pollen. You should plant flowers that provide a variety of nectar and pollen sources throughout the growing season.
Rose Tip #7: Last one! Plant families that will help attract beneficial insects to your rose garden, including:
- Apiaceae (or Umbelliferae) -Carrot Family- attracts lady bugs, parasitic wasps, and predatory flies.
- Lamiaceae or Labiatae -Mint family
- Asteraceae -Daisy Family- attracts hoverflies, lacewing, lady bug beetles, minute pirate bugs, and spiders.
We are a nation of gardeners. Thomas Jefferson grew over 300 varieties of plants at his Monticello home and like any dedicated gardener kept meticulous records detailing the triumphs (and failures) of his adventures in gardening. In the nineteenth century Italian immigrants introduced new vegetables like artichokes to the United States. Today, heirloom seeds originating from around the globe—or grandma’s backyard—can be purchased online and grown wherever we make a home. The Smithsonian Gardens Victory Garden at the National Museum of American History tells a story of citizens feeding their communities during wartime years, as well as a story of the diverse cultures that comprise the American people. In the summer ‘Carolina Gold’ rice, a traditional crop from the Carolina Lowcountry, can be found growing only a few feet from ‘Corbaci’ sweet peppers, a hard-to-find heirloom from Turkey.
April is National Garden Month, and we are celebrating the diversity of American gardens and the gardeners who make them grow. Small gardens and large gardens, community gardens and backyards, our diverse stories are part of a verdant quilt of gardens growing across the country. Gardens tell us where we’ve been, and where we are going. They can tell us stories about how people in our communities lived in the past and articulate our cultural values in the present. So often our everyday stories—the dahlias bred by a great-uncle, the nursery owned by a family for generations, the hot peppers grown as a reminder of a faraway island childhood—are lost to the historical record, and therefore lost to future generations.
Community of Gardens is our answer to the call to preserve our vernacular garden heritage. Community of Gardens is a digital archive hosted by Smithsonian Gardens, in partnership with our Archives of American Gardens, and created by YOU. It is a participatory archive that enriches and adds diversity to the history of gardening in the United States and encourages engagement with gardens on a local, community level. The website uses a multimedia platform that supports images, text, audio, and video. Visitors can add their own story to the digital archive, or explore personal stories of gardens from around the country.
To contribute a story to the digital archive visit the “Share a Story” page on the Community of Gardens website to sign up for an account. Once you have set up your account you may then add a written story and photographs. If you’d like to add video or audio files to your story email them to email@example.com. You will hear from a Smithsonian Gardens education staff member within a few days, and your story will be posted on the website usually within 3-5 business days. Once you have shared a story, share another story, or encourage your friends and neighbors to do the same!
We are looking for any story about gardens and gardening in America—even stories of Americans gardening abroad. Here is just a sampling of the stories we are looking to include in Community of Gardens:
- What’s growing in your own backyard, or on your apartment balcony? What motivates you to garden and how did you get your start? How does gardening enrich your everyday life?
- Interview a neighbor or family member about their garden.
- Memories of gardens past. Do you have strong memories of your grandparents’ garden, or visiting a public garden that no longer exists? Gardens can live on in stories and images through the archive.
- Family history. This is a good opportunity to get out the photo albums and scan old family photographs. Are you a fourth-generation gardener like Paul, pictured above?
- Community gardens—past and present.
- Did you immigrate to the United States from another country? How do your traditions and culture play a role in your garden?
- College and university gardens.
- School gardens. Involve your students in telling the story of their garden!
- Pollinator gardens and beekeeping.
- Americans gardening abroad. Are you a veteran or member of the Foreign Service? Did you keep a garden while living abroad? How did living in another country influence your garden?
- Sustainability and eco-friendly gardening.
- Stories of gardens committed to providing food access in urban areas.
Join us in preserving our national garden heritage—this month and every month. What is your garden story?

I had the opportunity to travel to Columbus, Ohio, last July to attend Cultivate ’14. This annual conference is held for people from all aspects of the horticulture industry, including growers, retailers, landscapers, interior plantscapers, floral designers, and educators. With educational sessions, the largest horticultural trade show in North America, wonderful tours to attend, and over 10,000 attendees, there was so much to see and learn while I was there.
As part of the conference, I was fortunate to be able to visit the Franklin Park Conservatory and Botanical Gardens in Columbus. I have always been fond of conservatories and greenhouses, and this one did not disappoint! The conservatory itself, comprised of 8,300 sq. ft. of glass roof space, first opened its doors to the public in 1895 to show off its collection of palms.
One aspect that really drew me in to all of the beautiful plant displays there were the Dale Chihuly glass pieces that were exhibited throughout the conservatory. I learned that Chihuly’s artwork was first displayed in the conservatory in 2003. Because of a marked increase in attendance, the Friends of the Conservatory decided to purchase many of those glass pieces so that they could be shown permanently. There is something about the way the beautiful glass, with its electric colors, reflects the sun in such a gorgeous setting. It warms me from the inside out.
That really got me thinking about how important art is in the garden: bringing these two elements together to draw in people to see the gardens. It is a way for gardeners and plant lovers to come to such a lovely, natural setting to appreciate art. It is equally as valuable to bring lovers of art into a garden setting, which is beautiful and imperfect—quite a different setting to display artwork than the stark white walls that we often see in a gallery—and enable them to appreciate the artwork in a more natural setting. The synergy created by placing these two components of artwork and gardens in the same space makes the combination of the two work that much more effectively together than they would on their own.
We at Smithsonian Gardens are so fortunate to have such a beautiful backdrop in which to display our plants. The museums themselves are works of art, inside and out. We have entire gardens that are dedicated to displaying artwork (such as the Hirshhorn’s Sculpture Garden), and others that are gardens, first and foremost, that also display artwork (the Haupt Garden, American Indian Museum, and Natural History Museum, to name a few).
I work primarily with plants used in interior spaces, and while I can’t necessarily work with “gardens” and artwork, the plants I grow and care for in the Smithsonian greenhouses are used inside the museums where even more pieces of art are displayed. The trip to Franklin Park Conservatory has inspired me to think more creatively about the plants I grow, and to consider new ways in which the plants can be arranged to complement the artwork they will be placed around, or even the space in which the plants will be displayed.
The next time you visit a space that displays horticulture and art, take the time to appreciate how much more you get out of your experience by having both plants and artwork working together.

They all go to Cultivate ’14 in Columbus, Ohio in July.
I had the wonderful experience of attending Cultivate ’14 in Columbus, Ohio July 12 – 15, 2014. Formally known as the Ohio Short Course, the symposium is one of the largest events in North America. The show is attended by over 9,000 garden retailers, greenhouse growers, landscapers, interior designers, educators, researchers, and many other professionals involved in the green industry.
Top notch educators and speakers are invited to speak on over 140 topics about pest control, new plant varieties, growing techniques, interior design, and green walls. Attendees have the flexibility to attend as many of the seminars as they can. Attending these seminars is a great way to get new ideas on growing techniques, identifying common diseases and insects that may attack greenhouse crops, and even proper techniques on using yellow, sticky insect trap cards.
The trade show is the one of the largest around. I was able to walk around at my leisure and see all of the new and innovative products that are available or will be made available to our industry in the future. The trade show is also a great time to network with sales representatives that I talk to sometimes on a weekly basis. I also establish new relationships with salespeople trying to sell the newest and brightest products in the industry. Personally, the trade show is a wonderful opportunity to “hook up” with former coworkers and sales representatives I have known for over twenty years.
One of the highlights of the show is getting to see many of the new plant varieties and introductions. There are hundreds of new and exciting plants and colors at the show. Aisle after aisle of annuals and perennials line the lobby at the convention center. Many of these new varieties can be seen in the fabulous displays all throughout the show. I gain a ton inspiration when looking at the wonderful new selections and then enjoy bringing all of my inspiration back to share with my coworkers at Smithsonian Gardens.
Another wonderful highlight of the trip is the bus tour to greenhouse operations in the Ohio area. I was able to tour two family owned production/retail facilities. Going on the tours allows me to see what other growers are doing and taking a peek at their innovative ways of producing large quantities of high quality plant material to be sold to retail garden centers. The bus trips also establish relationships with other people in the industry. Conversations are started and soon everyone on the bus seems to know one another. Information and ideas are exchanged while spending most of the day on the bus. These people on the bus come from all over the country. My bus had people that came all the way from Canada and Hawaii!
The really fun part of the trip to Cultivate ’14 was the visit to the Franklin Park Conservatory a couple of miles outside the city limits. Their display of Chihuly glass (more than 3,000 pieces in the permanent collection) was awesome! The plants displays were amazing as well. Highlights of the conservatory included a palm house, a rain forest, a butterfly house, lots of amazing bonsai, and a gift shop and café.
Attending Cultivate is always a wonderful experience. The event is truly a great opportunity to become motivated and inspired by all of the beauty and knowledge the show brings to the green industry and to me.

The common name rain lily comes from this plant’s tendency to bloom after a good soaking from Mother Nature. They are native to tropical and semi-tropical regions of the Americas. There are 3 genera commonly known as rain lilies – Zephyranthes, Habranthus, and Cooperia. Rain lilies are a perennial bulb with a hardiness of USDA Zones 7 to 11 for most species. They come in various colors, mostly ranging from pinks, yellows, and whites and new colors are popping up through hybridizing and breeding all the time. Although the common name would suggest that they are in the Liliaceae (lily) family, they actually fall under Amaryllidaceae.
Rain lilies are often grown in containers where they can be placed on a front porch or around a deck and will reward all season long. I have found that if grown in containers, they seem to prefer being slightly crowded and even somewhat pot-bound. They also look great along a pathway or in the front of a sunny border and are often used in rock gardens. To get the finest show, Rain lilies look best planted in masses. Most Rain lilies will bloom several times a season, usually after a good downpour.
If you live in a zone where Rain lilies are not hardy they are easy to overwinter. When it starts getting cooler, simply bring them indoors (either the container or, if planted, the dug up plants – if possible give them a quick potting) and keep them dry all winter, then set them outside again in the spring. You can pull off the foliage as it dies to keep them clean. You may want to either add soil or rough the edges of the pot prior to setting them outside if the soil has shrunk over the winter.
Rain lilies grow best in full sun to partial shade. They prefer to be kept evenly moist but can tolerate periodic dry spells without problem. During summer months use a well-balanced fertilizer (either liquid or slow release). The bulbs produce offsets which can be divided and planted in spring or you can sow seeds if you wish. If you are collecting seeds, sow right away before they dry as they tend to lose the ability to germinate and may take extra time to do so. Rain lilies are very gardener-friendly as they have no serious pest or disease issues. I have had problems with mealy bugs, however, but that is because I start watering them earlier in the season than normal and I keep them in the greenhouse for a fuller plant come spring. Be aware that all parts of the plant can be toxic if ingested.
After reading this, you may be eager to see some Rain lilies for yourself, so please stop by the Ripley Garden at the Smithsonian Institution this summer and enjoy their beauty. Some of the ones we display are Zephyranthes flavissima, Habranthus robustus ‘Russell Manning’, Habranthus texanus, and Zephyranthes candida.

Join us this Saturday, May 9th, from 10 a.m. to 3 p.m for a celebration of “Water, Water, Everywhere” at Garden Fest in the Enid A. Haupt Garden. In this blog entry Sarah Tietbohl writes about just one of the many ways we try to conserve water at Smithsonian Gardens.
When I first started at Smithsonian Gardens in 2010 I was assigned the job of cleaning the Moongate fountain in the Enid A. Haupt Garden. I was excited about this task as I would have an opportunity to learn to use a new piece of equipment and keep cool during the hot summer months. I estimated that the fountain would need to be cleaned maybe once a month. With the pond open between April and October, that would total seven times a year. That spring, the cleaning schedule started out at once a month. As the season went on and the temperatures climbed into the 90s, I noticed that the fountain was growing algae at a rapid pace. It turned the water a sickly slimy-green color. That once-a-month cleaning turned into scouring once or twice a week! That season, I ended up cleaning the fountain well over twenty times. The next year it was the same story.
After the summer of 2011, I really started to think about all of the water, energy, and time it takes to clean the Moongate fountain. I started to gauge the amount of water that was being used in one year to clean and fill the fountain. I calculated that it takes 2,300 gallons of water just to fill the fountain each time it is cleaned, plus 200 gallons or so to clean it. I decided to research environmentally-friendly products that would reduce the amount of algal growth, thereby cutting down on the amount of water needed to re-fill the fountain after each cleaning. Fewer cleaning sessions would also result in less emissions (and noise) generated from the power washer that runs every time the fountain is cleaned. I started experimenting with a non-toxic black pond dye. Adding black dye to the fountain reduced the amount of sunlight that was able to penetrate the water, which in turn reduced the algal growth. I found the dye to be very effective and talked my colleagues into using it in the fountains in the Ripley and Folger Gardens as well. Thanks to the black dye solution, Smithsonian Gardens has reduced fountain water use from 60,000 gallons a year to slightly less than 22,000 gallons- a terrific way for Smithsonian Gardens to employ a sustainable alternative in its operations.
