Dispatch from home: Early, small and pink

close up of flower cluster

In the spring of 1997 I came across an adorable little pink rhododendron called ‘Pink Snowflakes’. It was absolutely covered with small white flowers with a bright pink ruffled edge and a tiny smattering of pink dots in the throat.

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.

The Rare Plant Care and Conservation Program’s (Rare Care) partnership with the Washington Natural Heritage Program (WNHP) is invaluable and the relationships we build with their staff create a strong foundation for our program. As such, we like to spotlight the people we work with at WNHP like Joe Rocchio, the new Program Manager. Joe’s tenure for Heritage Programs began in 1999 when he worked for the Colorado Natural Heritage Program as a wetland ecologist.

Magnolias magnolias magnolias! Where to begin?! These harbingers of spring have started to bloom! The Washington Park Arboretum has 250 magnolia tree specimens, with some impressively mature trees dating back to 1940.

Seeding for the Future

View of White Bluffs and the habitat of White Bluffs bladder-pod with yellow flowers and bluffs that are sliding down the hill.

Last fall, the Rare Plant Care and Conservation Program (Rare Care) initiated a new study to investigate whether direct seeding is a viable alternative for establishing new populations of White Bluffs bladder-pod (Physaria douglasii ssp. tuplashensis). The only known population of this plant occurs at the Hanford Reach National Monument. It grows on the white bluffs along the east side of the Columbia River on a white cemented alkaline substrate rich in calcium.

The genus contains only ten species, four of which you can find growing here at the Washington Park Arboretum!  All species of Azara are evergreen shrubs to small trees.  Although some species of Azara are considered to be borderline hardy in our Pacific Northwest climate, we have had success growing them at the Arboretum.
