The Pacific Northwest is a mecca for huckleberries, which belong to the same family---Vaccinium---as blueberries. The red huckleberry, for example, grows in brambles along the Oregon coast, in addition to a range of elevations in the Coast Range, often in association with western hemlock and Sitka spruce. Human huckleberry pickers join a host of mammalian and avian fans of this bountiful crop, from mountain beavers to band-tailed pigeons to black bears.
The edible orange and yellow fruits of this understory shrub, which is especially fond of streamsides in lower-to-middle elevations, bring to mind the hue of a salmonid (and otherwise the general appearance of a blackberry). The triplet, compound leaves are serrated; the flowers, which often bloom early in the year, are pinkish-red.
Miner's lettuce, like some closely related species, has succulent, edible leaves that can be eaten raw---tasting somewhat like lettuce---or boiled, where it gains a deeper, richer flavor. Its moniker allegedly stems from its popularity among miners, who ate the plant for its vitamin C. Miner's lettuce grows in cool, moist areas. The configuration of a tall stem and white flowers growing above a circular leaf is distinctive.
Licorice Fern (pictured at the top)
This common fern's delicate, pinnate fronds and predilection for growing on logs and living trees help distinguish it. The rhizome can be chewed for the eponymous taste.
This familiar tri-leaved groundcover is found across much of North America; the Oregon coast supports both woods and the coastal strawberry. The fruits might be smaller than cultivated offerings, but one could argue they pack in more taste---plus, they're more fun to harvest in a summer forest than a grocery. Along the Oregon coast, they are widely distributed, from moist riparian beds to upper-elevation forests.
