Selected cuttings from the Washington Park Arboretum (April 15 – 28, 2014)

1)   Melicytus angustifolius

  • This southern hemisphere Violaceae relative thrives in rocky places in mountains or on coasts, or in evergreen forests.
  • Is ‘dioecious’ or ‘of two houses’ in Greek translation; male and female flowers are present on separate plants.

2)   Erica arborea var. alpina

  • Found along the southern end of Arboretum Drive, this is one of the older collections in the Washington Park Arboretum, dating back to 1947.
  • This form, var. alpina, is a smaller shrub, very hardy, and with brighter green foliage, making an imposing highlight among smaller heaths and heathers.

3)   Poncirus trifoliata  (syn. Citrus trifoliata)

  • Bitter, non-edible yellow fruits that resemble a small orange
  • Two large specimens in the Arboretum found in grid 8-1W and 12-B, north of the large parking lot off of Lake Washington Bouvelard.

4)   Viburnum carlesii var. bitchiuense

  • This spicy smelling Viburnum is the intoxicating fragrance you’ll be hit with the moment you walk out the front door of the Graham Visitor’s Center.
  • Listed on the IUCN Red List of Threatened Plants in 1997, our cultivation of this plant helps to preserve a propagation source for future plants.

5)   Phyllocladus alpinus

  • This New Zealand conifer can photosynthesize through highly modified, leaf-like shoots called phylloclades as well as through leaves.
  • The newly-formed seed cones are berry-like, with a fleshy white aril.
  • Male and female flowers are separate, but borne on the same plant.
