Preserving Australian Flora in the Washington Park Arboretum

blue green leaf-like branches

The Pacific Connections Garden (PCG), found at the southern end of the Arboretum, is a place that spurs the floristic imagination. Visitors traverse hemispheres and continents while moseying through gardens that showcase plant communities from specific regions in New Zealand, China, Cascadia, Chile, and Australia. In a short walk it’s possible to pass through our version of the New Zealand high country, continue on to the Cascadia garden, featuring plants native to the Siskiyou mountains, and finish with our representation of the wine palm and monkey puzzle laden temperate rainforests of Southern Chile.

The three white petals of Trillium are always a sign of spring.  As they age, the petals turn pink.
These native wildflowers are common under-story plants in our woods.
The seeds of Trillium contain a substance attractive to ants who act as seed dispersers.
Scattered populations of Trillium bloom throughout the native areas of the Arboretum.

1)   Acer palmatum ‘Katsura’                                                             Japanese Maple

Japanese maples have been cultivated in Japan for over 300 years. While they are most known for their stunning fall colors, I personally enjoy them as much in the spring for their new leaf color.
‘Katsura’ is a cultivar which appears to have bright orange new leaves, but on closer inspection, the leaves are bright yellow with a red margin.
