July evenings in the Idea Garden can be home to some pretty raucous behavior. At this time of year, young martins negotiate the air on untested wings as they return to the nest sites where they were hatched and raised.

In the remote flood plains of South America, a giant water lily blooms, attracts pollinator beetles, produces fruit and seed, and thus carries on through time. The discovery of Victoria regia, its world-wide cultivation, and the man-made works of beauty it inspired are the subjects of a new exhibit at Longwood Gardens entitled Secrets of Victoria: Water Lily Queen.

I recently returned home to Longwood after attending the 9th International Gardens without Limits Conference, Gardens & The Public: The Keys to Success, in Metz, France. I was fortunate and grateful to have the opportunity to be among 26 invited speakers and 400 attendees from around the world. The theme for the biennial gathering was “Welcome to the New Generation.” It was exciting to learn how other public gardens, parks, and greening organizations are working to broaden their base of support, welcome younger generations, and remain relevant.

One hundred different chrysanthemum flowers grafted onto one plant? What an extraordinary thought! Our mum team would love to take credit for this great idea; however, this horticulture art form has surprisingly been around for hundreds of years in China and Japan. Today you can find it on display in only two places worldwide, and Longwood Gardens is proud to be one of them.

Longwood is known for its recently-restored, 10,010 pipe, Aeolian organ (the largest ever constructed in a residential setting). This summer, we’ve received a lot of attention for our premier exhibit, Light: Installations by Bruce Munro. But, did you know that there was a time in Longwood’s history when the spirit of these two crowd-pleasing attractions converged?

It’s not a matter of “if” the Green Wall will get pests; it’s a matter of “when.” Longwood’s Integrated Pest Management (IPM) staff battles these pests with a non-chemical approach called biological control.

The first Himalayan blue-poppies (Meconopis ‘Lingholm’) of the season went on display at Longwood Gardens just before the opening of the Philadelphia Flower Show. Unlike last year when some plants went to Philadelphia, this time the blue-poppies can be seen only here at Longwood.

After 35 years of clivia breeding, Longwood Gardens is releasing its first named clivia when the North American Clivia Society holds its International Symposium and Show at Longwood Gardens March 19 and 20, 2011.

One of the most frequently asked questions on growing clivia is “how do I get my clivia to bloom?” Recently I visited with the Director of the North American Clivia Society and Executive Director of the Delaware Nature Society, Mike Riska, to get his expert advice on clivias. Mike has grown clivia for many years, and has won numerous awards for his plants—both from the Philadelphia Flower Show and from Longwood Gardens. In this video, he shares some pointers on how to get a clivia to bloom, and gave advice on growing and grooming your plants for competitions.

Longwood often hunts the globe for new or extraordinary plants to conserve and showcase in the Gardens. Recently, I went on a different sort of expedition—to inspect the plants for Longwood’s new East Conservatory Plaza green wall. My mission was to identify any potential pests or diseases that could threaten the new display.

Biocontainers offer an exciting opportunity for plant producers and home gardeners to become more earth friendly. Currently the majority of ornamental crops are produced in petroleum-based plastic containers. The extensive use of plastic results in a significant waste disposal problem and the plastic ends up in a landfill or hopefully gets recycled.

Cascade chrysanthemums have long been at the heart of Longwood Gardens' annual Chrysanthemum Festival. Longwood grows specialty mums (Chrysanthemum x moriflorum) that originated in China and Japan and are selected for their ability to create beautiful and lasting forms. Over the years, Longwood's amazing show of form and color has been continually modified and refined. Guests marvel at the captivating shapes and often ask us how we create these wonderful pieces of horticulture. The following is meant to highlight a little behind-the-scenes action and hint at some of the spectacular forms you will see this November in our Conservatory.

Our cannas are being threatened! Plants all around the world are being infected by viruses that can affect the beauty of the plants and can eventually lead to death. Unchecked, this could lead to the end of cannas. Do I have your attention? Well, don’t panic because here at Longwood we have some projects underway that will hopefully give new life to the beautiful canna!

Stop by the "Frog Hollow" area, to the West of the Chimes Tower to view the turf grass trial. Although simple in scope, this 5-year study could have a dramatic eco-friendly outcome for Longwood Gardens. Currently, staff mow the turf areas about once a week during the growing season—and there are a lot of turf areas throughout Longwood Gardens! If this study proves fruitful, then Longwood could replace some of its turf with a grass from this study and drastically reduce mowing in portions of the garden. This will greatly reduce fuel consumption and mower vehicle emissions.

In March of 2009 we posted a video of a Pileated woodpecker building a nest in a large dead tree (snag) in the woods at Longwood. This year, an Eastern Screech Owl (Otus asio)--a small (8 1/2 inches) nocturnal, woodland owl--has taken up residence in the same location, using the hole that the Pileated built...

Late March and early April is a time when people are ready to get out of the house and explore the outdoors after all the snow has melted and tiny springtime treasures begin to emerge. At Longwood Gardens we're just bursting at the seams with beautiful flowers 365 days of the year!

The past year has been an olfactory adventure in Longwood's research greenhouses. In preparation for Making Scents: the Art and Passion of Fragrance, we brought in a variety of fragrant plants for trial. Some plants, such as roses, are common and easy to obtain. Fragrant varieties such as Rosa ‘Secret’s out’, R. ‘Gros Choux d’Hollande, R. ‘De Resht’, R x centifolia, R. ‘Compte Chambord’, and ‘Jaques Cartier’ will be making an appearance in the Conservatory during the exhibition.

This year the Philadelphia International Flower Show produced by The Pennsylvania Horticultural Society (PHS), America's first horticultural institution, will showcase plants from around the world in the 2010 show “Passport to the World.” A special exhibit called the "Explorers Garden" will greet guests to the show, and will capture the spirit and adventure of early plant exploration. For the "Explorer’s Garden," Longwood is forcing its signature Victoria ‘Longwood Hybrid’ water-platters into bloom.

Longwood Gardens established hardiness trials and a breeding program in the early 1960’s to evaluate and develop camellias that can tolerate colder winters. These efforts have lead to the release of two of the hardiest Camellias ‘Longwood Centennial’ and ‘Longwood Valentine’. As Camellia breeding and hardiness evaluation continue at Longwood Gardens, the selection of commercially available hardy camellias will increase.

In March, our staff found a pair of Pileated Woodpeckers excavating a nest cavity in a large dead tree. We were lucky enough to capture the event on film and have been watching (and filming) their nesting habits ever since.
