@ossobuco,
A place I might enjoy checking out, right about now...

I think this is the scholar's garden:
From SFGate -
Lan Su Chinese Garden, Portland, Ore. Lan Su, Garden of Awakening Orchids, was modeled after the Ming Dynasty gardens of China. An atmosphere of tranquillity has been created by artisans from Suzhou, Portland's sister city. Visit early this month. Toss your red ribbon into the hong bao money tree or Chinese Wishing Tree in the Fragrance Courtyard. If it sticks, you'll receive good fortune in the new year. Every season is unique; one visit, never enough. 239 Northwest Everett St., (503) 228-8131.
I couldn't find a photo of the Fragrant Garden, at least in the time I looked, nor that particular wishing tree.
Here's another wishing tree, though:
I remember that Dys really liked this garden.
