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.

It’s April Fool’s Day! You know what that means . . . Don’t worry, we don’t have any tricks up our sleeves today. We’re going to let the plants pull all the pranks. We asked Smithsonian Gardens horticulturists to think of a few of their favorite plants that deceive and mislead both pollinators and gardeners alike. (Yes, we are anthropomorphizing here; guilty as charged!)
Tom Mirenda, Smithsonian Gardens orchid specialist and horticulturist, had many suggestions! Orchids are masters of trickery and deception.
Spiders, moths, ghosts, and vampires, oh my! Orchids might not normally comes to mind when you think of Halloween, but these fascinating members of the Orchidaceae family have adopted (and adapted) all sorts of creepy-crawly characteristics as strategies to survive. Some are on the list just because of their spooky names or association with human traditions. Smithsonian Gardens has a large collection of almost 8,000 orchids at our greenhouse facilities in Suitland, Maryland. The orchids come out to play once a year for a winter exhibit on the National Mall co-hosted with the United States Botanic Garden.
#10 Brassavola nodosa
Also known as the the “Lady of the Night” or “Flor de la Noche,” Brassavola nodosa has ghostly white flowers that emit strong a nocturnal fragrance to attract night-pollinating moths.
#9 Mediocalcar decoratum
Mediocalcar deocatum is more cute than creepy, with blooms that resemble Halloween candy corn!
#8 Brassia gireoudiana
Brassia species orchids and hybrids are also known as “spider orchids” due to their Arachnid-like looks. The orchids use visual mimicry to trick spider-parasitizing wasps into spreading their pollen. The wasp mistakes the orchid for a spider and attempts to lay its eggs there on the lip of the flower, taking pollen without even knowing it as it flies off to the next orchid. If it was a real spider, the wasp larvae would devour the spider as their first meal!
#7 Myrmecophila tibicinis
Myrmecophila tibicinis is literally the ant lover (its name means “ant lover”). Its hollow pseudobulbs provide a home for stinging ants. The ants secrete formic acid, which feeds the plant, and act as plant bodyguards in the dry season when thirsty animals are looking for a drink from a nice succulent bulb.
#6 Laelia anceps
This beautiful orchid is native to Mexico and traditionally used to decorate graveyards on for Day of
the Dead (Día de Muertos) festivities.
#5 Bulbophyllum phalaenopsis
Bulbo phalaenopsis is a smelly, carrion fly-pollinated orchid whose fragrance, according to an old taxonomic text, is said to be like the stench of 1,000 dead elephants rotting in the sun.
#4 Aeranthes antennophora
A genus mostly from Madagascar that’s believed to be pollinated by bats looking for moths to eat, which the flowers resemble.
#3 Dendrophylax lindenii
Made famous by the book The Orchid Thief, the Ghost Orchid is a rare orchid found in Florida, Cuba, and some islands in the Caribbean. We have a couple of examples of this leafless epiphyte in our greenhouses.
#2 Bulbophyllum medusae
Named for the most famous female Gorgon of Greek mythology, Bulbophyllum medusae has many bizarre umbels of flowers like a head of snakes.
#1 Dracula vampira
Dracula vampira takes the #1 spooky spot. You might want to bring garlic with you when seeking out this striking pleurothallid orchid with sharply pendant, black striped flowers and a lip like a mushroom.
