These cultivars are affiliated with Longwood Gardens in some manner. It is a diverse group and includes plants selected, named, or introduced by Longwood Gardens. These plants were procured in various ways. Some resulted from plant collecting expeditions, while others were among Mr. and Mrs. du Pont’s favorites. Many were bred by Longwood geneticists or acquired through seed exchange with other gardens, or were given to Longwood for introduction.
The majority have been developed and introduced within the past 50 years. However, a few plants have existed in the Gardens since the late 1700s, and some were planted by the du Ponts in the early 1900s. In the mid 1950s, Longwood began a breeding program to develop new cultivars. Today, outstanding cultivars are continually being selected and regularly introduced.
Bellow the highlighted plants is a complete list of Longwood Cultivars.
This plant was growing on Longwood property when P.S. du Pont purchased it in 1906, but it was not until nearly a century later that its outstanding form was recognized. The parent plant is twelve feet tall after more than 100 years and exhibits a densely-branched, nearly perfect round growth habit. The beautiful dark green foliage continues to darken throughout winter without the browning common to many boxwoods in colder climates, and contrasts exceptionally well with its red overwintering buds. This cultivar has proven extremely tolerant of drought, cold and other environmental stresses and is hardy to at least zone 6.
Selected among seedlings grown from seed collected on the 1984 expedition to SochongIsland in the Yellow Sea off the west coast of . A small number of seedlings proved to be hardy outdoors at (USDA zone 6) for more than 20 years. ‘Longwood Centennial’ was selected because of its exceptionally handsome, glossy foliage and dense, full growth habit. The cultivar may reach twelve feet in 20 years and is an excellent broad-leaved evergreen for areas where temperatures stay above -24C. Its flowers are red and typical of the species.
Selected among seedlings grown from seed collected on the 1984 expedition to Sochong Island in the Yellow Sea off the west coast of South Korea. A small number of seedlings proved to be hardy outdoors at Longwood Gardens (USDA zone 6) for more than 20 years. Reaching twelve feet in 20 years, ‘Longwood Valentine’ is the most floriferous of all the camellias collected in the 1984 expedition. Flowering typically occurs in early to mid spring, but in warm winters, flowers may open as early as January and continue through April. Flowers are red, slightly larger and more widely open than is typical for the species.
This cultivar is a low, compact, trailing form with a unique history linked to Longwood Gardens. The original plant specimen was found by two of Longwood Gardens’ plant explorers, Edward G. Corbett and Richard W. Lighty, along the beach on Cheju Island in Korea. Its form caught the keen eyes of these explorers who noticed its prostrate stems which arch upward at the tips displaying tight clusters of soft blue flowers. This cultivar attains heights of one foot with a larger spread and flowers from late summer into autumn on current season’s growth. The blue flowers are also an excellent late-season butterfly nectar source. This cultivar’s size, silvery-aromatic foliage and attractive late season blue flowers make this plant an ideal addition to any late summer, early fall garden. USDA zone 7 or 6 with protection.
Named at Longwood Gardens, but of the same provenance as famed ‘Winterthur’. This Viburnum will be released to nurseries in 2008 for the first time! The selection has a compact, dense growth habit (five feet in height after 15 years), a prolific fruit set and handsome glossy foliage turning bright wine-red in the fall. Its ability to thrive in the Longwood Gardens visitor center parking lot for 15 years proves its adaptability and tough nature (USDA zone 6).
