Cusick’s Camas

By Paul Slichter
Local botanists have long recognized several patches of an odd camas growing above the Klickitat River. They didn’t quite match the Suksdorf’s camas (Camassia leichtlinii ssp. suksdorfii) or common camas (both C. quamash ssp. breviflora and ssp. quamash) which are the local camas in the area.
Fortunately, Susan Kephart, a specialist in camas taxonomy, was invited to look at the unusual camas by local plant enthusiast, Barbara Robinson.

Unlike the Schefflera houseplant that may seem familiar to some, this interesting character is cold hardy and grows exceptionally well in outdoor Pacific Northwest settings.
Bold evergreen leaves form an umbrella-like canopy. As the new leaves slowly develop, they are covered in tan indumentum, but eventually become a beautiful dark green.
Pale yellow flower spikes reaching upwards of three feet emerge in early autumn for a unique display.

Counting the Endangered Wenatchee Mountains Checkermallow

Picture of volunteers in meadow with flagging to mark checkermallow plants

We can now answer the question, with a high degree of confidence, of just how many Wenatchee Mountains checkermallow (Sidalcea oregana var. calva) plants there are. That’s due to a 9-year effort to count and map its largest known population at Camas Lands near Peshastin, WA. This population holds nearly 90% of all known individuals of this species; therefore, it is important to know how large this population is and how it is changing over time.

A Town Called Malus

Close-up photo of Malus x adstringens

This week’s selections honor the area we call Crabapple Meadow and the residing collections therein.  Each summer, the Meadow becomes home base for our annual summer camp participants and instructors and with this year’s season winding down, we feel it is a good time to recognize a handful of our terrific Malus specimens.
1)   Malus  ‘Sundog’

The “Flowering Crabs” comprise a genus of some 35 species of deciduous trees found throughout northern temperate regions.
