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.

  • Poinsettia

    In the late 1820’s Joel Poinsett sent cuttings of Euphorbia pulcherrima from Mexico to the United States.  When people saw that the bracts of this species turned red around Christmas, it was put into commercial production for holiday sale.  Thus, the poinsettia became a favorite emblem of Christmas.  By the mid-1900’s, poinsettia breeders began to experiment with bract color.  Today, poinsettias come in a range of colors and shapes and are the top selling potted flowering plant each year.
  • Thanksgiving Cactus

    Native to rainforests in Brazil, Schlumbergera grow as epiphytes, mainly on trees or shrubs but sometimes in shady places among rocks.  They do not have true leaves but flattened succulent stems.  Schlumbergera flowers bloom directly from the stems at the nodules and come in a variety of colors.  The hybrid ‘Thor Carmen’ is a tough houseplant that has showy flowers that bloom in the late fall, usually around Thanksgiving, hence the common name Thanksgiving cactus.  Sometimes confused with the true Christmas cactus (Schlumbergera x buckleyi), however, one can tell them apart because the Thanksgiving cactus has claw-like appendages on its stems that resemble crab claws.
