January 23rd, 2012 by Pat Chinn-Sloan
Selected cuttings from the Washington Park Arboretum for the 2nd half of January 2012
Selected cuttings from the Washington Park Arboretum (January 17 – 31, 2012)

1)  Camellia sasanqua    ’Shichi Fukujin’

  • An upright to spreading shrub or small tree with elliptical, dark green leaves and bearing single cup-shaped flowers, C. sasanqua is one of many camellia species native to Japan.
  • Known to flower early in the season when colors are greatly appreciated, it is considered a less spectacular shrub than the spring-flowering C. japonica.
  • Located in the Witt Winter Garden.

2)  Daphniphyllum macropodum

  • The large evergreen leaves of D. macropodum are similar to those of many rhododendrons throughout our region, but it is the red petioles and the bluish-black fruit which give this plant its distinguishing appearance.
  • Native to China, Korea, and Japan.
  • Located west of the Upper Trail, just south of the Lookout Gazebo.

3)  Hamamelis x intermedia    ’Winter Beauty’

  • The crimped petals or “ribbons” on the bare branches of the Chinese Witch-hazel are always a welcome sight during the winter season.  The orange spider-shaped flowers displayed here are no exception.
  • One’s sense of smell is also rewarded by the cold-resistant, fragrant flowers.
  • Located in the Witt Winter Garden.

4)  Berberis    ’Arthur Menzies’

  • An erect shrub with pinnate leaves and sharply-toothed dark green leaflets.  Yellow flowers occur in 5-to-10 inch long inflorescences in December-January.
  • Located near Arboretum Drive in the Rhododendron Glen.

5)  Quercus suber   (Cork oak)

  • Native to the western Mediterranean and North Africa, Q. suber is a rounded evergreen tree with thick, corky bark.
  • Located along Arboretum Drive near the rock roses.

January 2012 Plant Profile: Salix lasiandra

January 13th, 2012 by Soest Gardener, Riz Reyes

Happy New Year, everyone! It’s been a very mild winter season so far and and we’ve been blessed with several cool and clear days that bring out the best in the winter landscape. Working out in the Union Bay Natural Area, I was drawn by the picturesque views of the bay and looking out into the restoration sites, I also couldn’t help but notice the glowing stems of vibrant willows. Naturally occurring in consistently wet areas, UBNA just seems to glow and you can’t help but stop and admire them especially on a sunny day. UBNA is home to several species of willow, but the Pacific Willow stands out the most.

In the managed landscape, there are several species and cultivated varieties of Salix that are highly attractive. Salix alba, a European species, comes to mind along with the cultivars ‘Golden Curls’ and ‘Scarlet Curls’ derived as hybrids from S. matsudama ‘Tortuosa’, the famous “corkscrew willow”. These plants are fast growing and are often best coppiced in the winter or late springtime to get the slimmest stems with the most intense color the following year. This is achieved by taking down the shrub to about 6-10 inches tall and allowing new growth to develop from the base.

Common Name: Pacific Willow
Family: Salicaceae
Location: Union Bay Natural Area
Origin: Pacific Northwest Native
Height and spread: 20-30ft. high and 10-15ft. wide.
Bloom Time: Late winter
