Trees of the Lagoon

The peninsula north of the Linden Parking Lot (#16) is sometimes referred to as the Lagoon.  Enjoy these trees while walking, birding, viewing wildlife, or boating.

1)     Nothofagus antarctica                                                 Antarctic Beech

  • This tree is native to southern Chile and Argentina.
  • A deciduous tree with shaggy bark and small glossy leaves can be found north of the canoe launch.
  • It was once believed to be the southernmost growing tree on Earth until 2019, when a Nothofagus betuloides was found on the same island just slightly further south on Hornos Island, Chile.

2)    Ostrya japonica                                                         East Asian Hop-hornbeam

  • Ostrya japonica is native to Japan, China, and Korea and grows mainly at higher elevations (4,000-9,000 feet).
  • The smooth bark and spreading nature of the canopy make this a rather attractive tree in the garden.
  • Currently, the pale green hop-like catkins are on display.

3)     Quercus robur                                                                 English Oak

  • These long-lived oaks are a popular tree in Europe with the oldest believed to be over 1,500 years old.
  • This oak has one of the most spreading canopies in the Lagoon.
  • Quercus robur provide valuable timber for humans and also have valuable food sources for insects and wildlife.

4)     Salix fragilis                                                                  Crack Willow

  • This willow, a fast-growing tree with an irregular canopy, is native to Europe and Asia.
  • The Crack Willow bordering the canoe launch lives up to its name, as a large section of it cracked and is now tipped into the lake in an artistic fashion.
  • Unfortunately, this tree has escaped cultivation and is considered invasive in New Zealand, South Africa, and parts of the United States.

  • This Tilia has a coarsely-toothed leaf margin that is unusual for the genus.
  • Tilia mongolica is native to Mongolia, eastern Russia, and northern China.
  • This tree was discovered by French botanist Pere David in 1864 and was introduced to Arnold Arboretum, the oldest public arboretum in North America, by 1882.
