1)   Acer palmatum ‘Beni otake’                          “Big Red Bamboo”

  • This linearilobum type of Japanese maple has long, strap-like lobes to its leaves and an upright-layered form.
  • Fall color of this maple is deep crimson and can be seen next to parking lot 11 in the Woodland Garden.

2)   Acer palmatum ’Shigitatsu sawa’        “Snipes, quacking, flying up from a swamp”

  • This variegated Japanese maple of the Amoenum type has a pale yellow blade, divided by deep green veins with a pale pinkish blush at the lobe tips.
  • This tree can be found next to our Washington elm tree, just south on Arboretum Drive from the Graham Visitor Center.
  • The leaf color will darken to light green during the summer and become a reddish tone in the fall.

3)   Acer palmatum ‘Koshimino’                          “Straw Raincoat”

  • The sessiliform leaves of this Japanese maple are very unusual. The lobes are broad and toothed, but narrow to a petiole-like thinness which attaches directly to the twig without a petiole.
  • Fall color is a blend of light oranges and yellows.
  • This tree is located just uphill from Acer palmatum ‘Beni otake’.

4)   Acer palmatum ‘Ueno yama’        “Park with flowering cherries on a high mountain”

  • The leaves of this Japanese maple are known for their striking and long-lasting orange spring color.
  • The fall color is underwhelming comparatively with blended light oranges and yellows.
  • A fine, but snow-damaged specimen is located on the east side of Arboretum Drive, just south of the Graham Visitors Center.

5)   Acer palmatum ‘Watnong’                          “Little Hill”

  • This excellent tree has the typical weeping habit of the dissectum group of Japanese maples.
  • The new growth consists of light reds, pinks and greens, which give the tree a colorful appearance throughout the growing season.
  • Fall color of this specimen is bright scarlet-orange and can be seen on the east side of Arboretum Drive in the Woodland Garden.
