From our humble beginnings as a Quaker farmstead and arboretum, to Pierre S. du Pont’s forward-thinking stewardship, to today’s collection of renowned landscape designers, horticulturists, and architects, our great garden of the world evolves and emerges again and again.

Through Longwood Gardens and its program of outstanding horticultural display, every visitor to the Gardens has the opportunity to gain, culturally and spiritually, a better peace of mind.

  • American Holly

    This pyramidal tree, with spiny evergreen foliage, will grow up to 50 feet tall. Starting in October, the female trees of this US native produce red berry-like fruit that persist into winter, providing an important food source in the late fall and winter to birds and mammals. A nearby male pollinator is necessary for fruit production. American holly grows well in acidic, well-drained soil and will tolerate most light conditions, but prefers full sun and protection from the wind.  Like most fruiting hollies, it is a traditional favorite in winter holiday decorations and displays.
  • Tatarian Dogwood

    Several shrubby dogwoods, such as Cornus alba, are prized for their vibrant red, orange or yellow colored bark during the bleak winter months. The stem color is most pronounced on young branches and it intensifies in late winter, especially when temperatures drop below freezing.  This Tatarian or red-stemmed dogwood has a compact form and bright red stems along the shores of our Large Lake.
