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.

  • Bulbinella

    Bulbinella latifolia ssp. doleritica features long narrow leaves that grow in dense rosettes. The flowers are bright yellow-orange and appear in tall spikes. Doleritica refers to its preference for dolerite, a type of volcanic rock found in eastern regions of South Africa. This plant thrives in the nutrient-poor soils formed from these rocks, showing how plants can adapt to very specific ecological niches. Well-adapted to survive in drought conditions, it stores water in its fleshy roots, which helps it endure long dry spells common in its natural habitat. The bright tubular flowers are adapted for bird pollination, particularly for sunbirds that are attracted to their color and nectar.


     
  • Amaryllis

    Amaryllis is widely recognized as a classic holiday flowering plant, especially in winter and around Christmas. It belongs to the Amaryllidaceae family and is native to South Africa, where its natural growth cycle has made it well suited to winter blooming in cultivation. Grown from a large bulb, amaryllis is valued for its tall, upright stems and large, trumpet-shaped flowers, which provide vibrant color indoors when few other plants are in bloom. Botanically, most holiday “amaryllis” sold commercially are actually Hippeastrum, a closely related genus from South America, but the name amaryllis remains firmly associated with winter holidays and indoor flowering traditions.  After flowering, allow the leaves to grow, and continue watering and feeding the plant so the bulb can store energy, then let it rest for about 8–10 weeks in a cool, dry place before being replanted to trigger the next bloom.  Bulbs can last for years when stored correctly.  Enjoy a splendid variety of Amaryllis throughout the Conservatories!
