March Color Appears at the Washington Park Arboretum

March 19th, 2012 by Pat Chinn-Sloan

Selected cuttings from the Washington Park Arboretum for March 12-26, 2012

1)  Coriaria napalensis

  • This is one of three species of Coriaria in the Arboretum.
  • It is growing near Azalea Way, north of the Pine Collection (grid 23-1W).
  • Our other two species are C. japonica in Rhododendron Glen and C. sarmentosa (a New Zealand native) on Arboretum Drive in grid 11-7E.

2)  Lindera obtusiloba

  • Native to China, Japan, and Korea
  • L. obtusiloba is most noted for its early spring flowers, but also has rare fall color (pure yellow) on its openly-spreading form.
  • See it in the Woodland Garden or west of the Graham Visitors Center.

3)  Mahonia aquifolium   (Tall Oregon Grape)

  • Mahonia is now officially renamed “Berberis”.
  • Native to western North America; now in bloom throughout the Arboretum.

4)  Pieris japonica   ‘Valentine’s Day’

  • This pink cultivar is at the south end of our Lilac Collection in 29-1W on Azalea Way.
  • More Pieris as well as several other genera in the Erica family (Clethra, Kalmia, Vaccinium, and others) can be found on the lower trail north of Rhododendron Glen.

5)  Ruscus aculeatus   (Butcher’s Broom)

  • Ruscus is, surprisingly, a member of the Iris family.
  • The “leaves” are actually modified stems called cladodes; the tiny flowers and subsequent berries that seem to be in the center of the leaf are actually at the leaf axil.
  • These plants are in the north end of the Winter Garden.
