Longwood Cultivars

This compilation of the cultivated varieties lists those 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.
