This week I took a break from work on the Orchids: Interlocking Science and Beauty exhibition to help Smithsonian Gardens’ horticulturists with planters in the Robert and Arlene Kogod Courtyard at the Donald W. Reynolds Center for American Art and Portraiture. The Reynolds Center, which houses the Smithsonian’s National Portrait Gallery and Smithsonian American Art Museum, underwent a major renovation in the early 2000s to enclose its central courtyard, creating a beautifully maintained interior space filled with natural light. If you are a fan of architecture or just like cafes in nice spaces, you should definitely go check it out! Smithsonian Gardens’ horticulturists care for eight large planters throughout the courtyard and I’ve made two trips over the past couple weeks to help replace plants in two of the eight planters. With each planter over 300 square feet, it’s quite the production.
In fact, on Kogod changeout days, help is needed from several members of the Smithsonian Gardens staff. This week, I joined a team of five staff members and one volunteer to tackle the job. Changeouts occur regularly. Often new plants are rotated onto display for seasonal purposes or to freshen up the courtyard for the many thousands of visitors that regularly pass through. Earlier this year, the courtyard display featured Cymbidium orchids and their endless blooms gave spectacular color to the space.
Kogod changeouts not only address aesthetic purposes. Changeouts are also useful for ensuring and maintaining plant health. Sometimes a new plant may not do so well in the space. There might be a pest problem that requires removing a plant or a plant may simply need to come out because its life cycle is ending. Whatever the reason, making the effort to assess each plant’s health ensures a beautiful display.
During the first step of a planter changeout, all the plants (except for the trees) come out of the planter and are placed onto tarps laid out on the ground. Plants are assessed to determine whether they are still in good condition for display, if they need attention, or if they should simply be composted. Once the current plants are sorted, new soil is poured into the bed to level the surface with the edge of the planter. Once again, adding soil serves both an aesthetic and functional purpose. Fresh soil both looks better and allows the new plants going into the planter to have an easier time rooting. This is one of the most labor-intensive parts of the process as each of the planters easily takes in 80 50-pound bags of new soil.
Once the soil is in, additional nutrients are added and mixed in evenly before introducing the plants. The Smithsonian Gardens’ interior plantscape designer and crew then work to create a planter design with the plants available instead of trying to fit the plants into a predesigned plan. I feel this allows the planters to come out looking their best and showcases plants that we may have been able to save from the previous design that we did not expect to have. After helping with two changeouts, it’s really a nice surprise to see how it all comes together each time.
The next time you are visiting the Smithsonian American Art Museum or National Portrait Gallery, make sure to swing by the Kogod Courtyard and enjoy the wonderful green inside, no matter what the weather may be like outside!

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.

This summer, many exciting things happened with the Smithsonian Gardens Orchid Collection (SGOC). Not only are the greenhouses getting a good cleaning and reorganization, but Smithsonian Gardens is seeing significant additions to its species collection. In March, SGOC’s tropical species became an accredited collection with the North American Plant Collections Consortium. As you may recall from reading about the accreditation on the blog this past spring, this designation comes with a responsibility to continually improve collections management practices and species representation.
In June, Smithsonian Gardens’ terrestrial orchids received quite a boost in numbers. Collection managers Tom Mirenda and Sarah Hedean made a trip to a local nursery to purchase Paphiopedilums and Phragmipediums. They found many valuable additions for the collection, including a blooming-size Phragmipedium kovachii and several associated hybrids. We will hopefully see these spectacular kovachii flowers within a year. Additional Phragmipediums were obtained from another nursery, including Phragmipedium brasiliense, Phragmipedium boisserianum and Phragmipedium sargentianum. All three species are new to the collection.
June was a very busy month for accessions. At the end of the month, Tom flew out to California to speak at the request of Orchid Digest and during his trip, was able to stop by a local nursery to purchase almost sixty additional plants for the collection. This purchase includes a number of new species that address collection gaps identified by SGOC’s 2013 benchmarking study.
In August, four species of Pterostylis in the form of bulbs were donated to the collection. These propagules are from orchids that won the highest possible score from the American Orchid Society for specimen plants (99 points). Since these are colony-forming species, these propagules will be clones of the highly-awarded individuals. In this same donation we also received several bulbs of a Diuris hybrid. Diuris is commonly known as the Donkey Orchid due to the fact that two of the petals emerge from the top of the flower like donkey ears.
This fall, SGOC received an influx of Cattleya hybrids in anticipation of the 2015 Orchid Exhibit and the San Diego Zoo Botanical Collection sent Smithsonian Gardens a Paphiopedilum tigrinum in exchange for one of our Psychopsis hybrids.
It is very exciting to see significant progress made this yeat towards achieving our goal to improve the tropical species collection. Hopefully the momentum will continue into 2015 and beyond!

BOO! In honor of Halloween, we are celebrating another #SpookyPlantsWeek. Here’s our round-up of the weird, creepy, gross, scary, and wonderful plants that we featured on Facebook this week. All can be found growing in our gardens at the Smithsonian museums or in our greenhouses in Maryland.
This monocarpic, herbaceous banana is a wonderful specimen in any garden. Monocarpic describes plants that flower, set seed, and then die. Ensete superbum, or cliff banana, is native to India and has a conical pseudo-stem made up of overlapping leaf sheaths. Its bright green leaves, reaching six feet in length, drop during winter. The plant may reach ten to twelve feet while blooming. The inflorescence (or flower head) is a curved terminal spike with triangular oblong fruits and reddish brown bracts that persist for some time to add ornamental value. This banana, unlike many others, does not produce suckers and only reproduces by seed. In some extraordinary cases, plants in the wild can go into a three to four year dormancy period.
This rare plant in now on display in the Enid A. Haupt Garden. You can see it for a limited time just inside the west entrance to the garden, close to the entrance to the S. Dillon Ripley Center.

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.
