Selected cuttings from the Washington Park Arboretum for 6/4/12-6/18/12

1)   Argyrocytisus battandieri  (Pineapple Broom)

  • Don’t worry if you can’t pronounce the Latin name; the common name tells it like it is.
  • Yellow, “pineapple”-scented, leguminous flowers with silvery foliage.
  • This drought-tolerant shrub from Morocco is one tough plant that thrives in poor soils.
  • Named for the French pharmacist and botanist, Jules Aimé Battandier.
  • Located along Arboretum Drive in our Legume Collections.

2)   Crataegus x lavallei  ‘Carrierei’ (Carrière’s Hawthorn)

  • Our signature Woodland Garden tree
  • Now a common small landscape hawthorn used around Seattle.
  • Glossy, dark green quasi-evergreen leaves with clusters of white flowers in the spring.

3)   Hydrangea anomala ssp. petiolaris  (Climbing Hydrangea)

  • White blooms, yellow fall foliage, and exfoliating cinnamon bark create multi-seasonal interest.
  • “There is no better climbing vine,” says Donald Wyman, authority on woody plants.
  • Native to western Korea, Japan and Taiwan.
  • Several located in the Arboretum, climbing up Douglas Firs as high as 60 feet!

4)   Leptospermum lanigerum  (Woolly Tea Tree)

  • Handsome erect shrub approximately 9 feet tall. All parts are covered with soft down.
  • Native to Australia.
  • Located in the Australia Entry Garden of the Pacific Connections Garden.

5)   Pterocarya macroptera  (Large-winged Wingnut)

  • Deciduous tree native to China, quite striking in fruit.
  • As its name suggests, the Wingnut produces winged nuts but unlike the walnut, they are not generally eaten.
  • Located in the old nursery, off of Arboretum Drive.
