As a relative of the cultivated red raspberry, thimbleberry is a Northwest native shrub whose fruit resembles the shape of a thimble. And it's delicious! 
 
From WSU Clark County Extension:
This deciduous shrub grows to a height of 8’ at maturity in dense clumps via under-ground network of rhizomes. New shoots, referred to as primocanes, come up the first year and then overwinter and bear fruit during the 2nd and 3rd years. Unlike raspberries and blackberries, thimbleberry shoots lack thorns.
 
Thimbleberry grows well on a wide array of sites from moist to dry. This species is considered moderately shade tolerant.

Birds, squirrels, and chipmunks all greatly enjoy the ripe fruit.
