1)  Corylus colurna                     Turkish Hazelnut or Filbert

  • The Turkish Hazelnut is native to southeastern Europe into western Asia.
  • In summer, edible nuts are produced inside dramatically styled husks.
  • The Turkish Filbert can be found along Foster Island Road, opposite the Broadmoor gatehouse.

2)  Hydrangea macrophylla ‘Sumida-no-hanabi’                     Bigleaf Hydrangea

  • ‘Sumida-no-hanabi’ translates to “fireworks over the Hanabi River”.
  • This wonderful hydrangea can be found in the Centennial Garden along Azalea Way.

3)  Magnolia grandiflora                     Southern Magnolia

  • Stunning flowers in both beauty and scent are produced in mid-summer from these statuesque evergreen trees.
  • Though native to the southeastern U.S., certain selections of M. grandiflora are hardy to zones 5b, or around -15 degrees F.

4)  Picea smithiana                     West Himalayan Spruce

  • Also known as the Morinda Spruce, this tree can grow to over 200 feet in its native range.
  • The needles of Picea smithiana are among the longest of the genus.
  • Specimens of Picea smithiana can be found on the Sino-Himalayan hillside and along the Arboretum’s eastern fence line in our Sorbus Collection.

5)  Poliothyrsis sinensis                     Chinese Pearlbloom

  • The fragrant, white flower buds of Poliothysis open only slightly, retaining a spherical shape, thus the common name of Pearlbloom.
