One definition of a "standard" is a norm by which similar things can be measured. In horticulture, however, a standard is a plant that is trained or grafted to have a single stem, and a crown of leaves and flowers. Combine the two meanings, and you have the degree of excellence achieved by Longwood in the beauty of its standard forms. Photo by Larry Albee.

This fall, be sure to explore our Bonsai Display, where some of the best surprises of Chrysanthemum Festival come in small packages. Anemone Chrysanthemum x morifulium ‘Kotoi No Kaori’, photo by William Hill.

This year, 230,000 chrysanthemum blooms fill our 4-acre Conservatory in forms of cascades, shields, spirals, pagodas and of course, our most impressive Thousand Bloom Mum yet, featuring 1,515 blooms.

As Longwood's new Meadow Garden enters its first fall season, gardener Colin McCallum-Cook shares his expertise and excitement about the plants that make up the Meadow's palette of Autumn's Colors.

Pierre S. du Pont's extraordinary Main Fountain Garden has entertained guests with its beauty and showmanship for eighty-three years. Now Longwood Gardens will carry Mr. du Pont's legacy to New Heights through the Fountain Revitalization Project that begins in mid-October.

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.

Gardens are always changing. While the Mona Lisa hangs in the Louvre looking much as it did 500 years ago, every year, every season, and even every hour you are in a garden it is constantly in flux. As a gardener you can either try to fight this change or work with it. In the 10 years I have been working in Peirce’s Woods I have done both.

Our historic orchid growing houses, normally open only to Longwood’s staff, were constructed between 1926 and 1962. Today we use these houses to grow and care for the nearly 9,000 orchids in our collection. Visit us this Saturday, March 23, 2013, for our final Beyond the Garden Gates Day of the Orchid Extravaganza season, when you’ll have the rare chance to visit these spaces in person.

The tradition of orchids at Longwood Gardens began with a gift. In 1922, twelve Cattleya orchids were included in a gift of greenhouse plants from Mrs. Dimmick of Scranton, Pennsylvania to Mrs. Alice B. du Pont. It might have ended there, as one-time gifts sometimes do. These first orchids did not fare well, due to the grower’s limited knowledge of their needs and habits.

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.

The American Elm was once a staple on the streets of America until Dutch elm disease was introduced in the 1930s. Today, small groups of elm trees can still be found in the woods or on the side of the road, but it is rare to find large specimens along streets or in landscapes. The American elm on the Cow Lot at Longwood Gardens is the only straight species of American elm remaining in the Gardens. Standing just outside the Visitor Center, this tree provides a majestic welcome to our guests, and gives everyone a taste of what's to come as they begin their way through the Gardens.

Ever wonder what is going on in the greenhouses at this time of the year? While you are enjoying the beautiful summer display, Longwood's growers are already getting ready for fall! One of our biggest projects at this time of year is to complete the grafting process that allows us to grow the large specialty chrysanthemums that will be on display during our Chrysanthemum Festival.

When you hear the word “garden,” chances are you think of green plants and brightly colored flowers blooming under a bright sun. But did you know that there’s such a thing as a night garden, too—a garden is designed to thrill the senses when the sun has gone down, the air is cool and the bustle of the day has diminished?

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.

Longwood Gardens has so much to offer in the way of trees. Thanks to Pierre du Pont, we have this beautiful garden and its amazing old trees. Pierre bought the land for exactly that reason: to save a group of trees. The trees that he saved are incredible specimens, but I am here to tell you about the giants living among us.

“The longer I live the more beautiful life becomes. If you foolishly ignore beauty, you will soon find yourself without it. Your life will be impoverished. But if you invest in beauty, it will remain with you all the days of your life.” (Franklin Lloyd Wright)

I am excited to introduce to you a completely new type of Fireworks at Longwood Gardens—Clivia miniata ‘Longwood Fireworks’!

The tall, single stemmed chrysanthemums you see in the Conservatory here at Longwood Gardens are quite different than the mounded shrubs loaded with small flowers that you find at your local garden center. These are a specialty florist type, the product of hundreds of years of breeding to reach those stately heights and flower size and are not winter hardy for us in Southeast Pennsylvania.

Do you hear the word chrysanthemum and picture those simple household flowers from the local garden shop? At Longwood Gardens, we take the ordinary mum and make it extraordinary, turning it into a work of art—the Thousand Bloom Chrysanthemum!

In January 2010, we posted a blog about our “King of the Conservatory,” Encephalartos woodii. The Encephalartos is the most prized plant in Longwood’s Conservatory since it is extinct in its native environment of South Africa.
