Various Dates
Siberian miner's lettuce/Candy flower (Claytonia sibirica - Portulaceae family). Leaves edible (but not, per Pojar, usually eaten by native folks). Used externally for syphilis, headache and constipation. Whole plant eaten to induce labor or to ensure "baby would be soft when born."
Large-leaved avens (Geum macrophyllum - Rosaceae family). Per Pojar: "Nuxalk made tea from the roots for stomach pains, and the leaves were poulticed on boils" by several tribes. Leaves were also used for several pregnancy related issues (both aiding delivery and preventing additional pregnancies). Also used in diuretic tea and as eyewash. Roots used to make steambath for rheumatism.
Fringecup (Tellima grandiflora - Saxifrage family). Per Pojar "The Skagit pounded fringecup, boiled it and drank the tea ofr any kind of sickness, especially the lack of appetite. It was also known as a 'special' medicine to some Ditidaht people. Fringcup was said to be eaten by woodland elves to improve night vision."
Wood sorrel (Oxalis oregana - Olixadaceae family). In shade and with leaves contracted in response to sun/heat.
Western Starflower/Indian Potato (Trientalis latifolia - Myrsinaceae family). Per Pojar: "The plump firm tubers reportedly were gathered for food by some coastal aboriginal groups."
Bugs doin it.
Salmonberry (Rubus spectabilis - Rosaceae family). In various stages of becoming a berry.
Pacific waterleaf (Hydrophyllum tenuipes - Hydrophyllaceae family). Roots eaten by Cowlitz people.
Pacific/trailing blackberry (Rubus ursinus - Rosaceae family). Only native blackberry. Berries edible (ripe in July timeframe usually), some prefer them to the more common invasive Himalayan. Per Pojar: "A tea was made with the dried leaves, which were thought to be best collected in the fall when they turn red. The leaves and roots were used to treat diarrhea, dysentery, cholera, excessive menstruation, fevers, haemorrhoids & sores in the mouth. The leaves were added to bitter medicines to sweeten the flavor." Male & female plants are separate; not uncommon to find large patches of male bushes without fruit.
False Solomon's seal (Smilacina racemosa - Liliaceae family/Maianthemum racemosum - Asparagaceae). Roots used medicinally, berries edible but not palatable.
Nootka rose
Dull Oregon-grape (Mahonia nervosa - Berberidaceae family). Fruits edible, leaves tasty and lemony when very young. Per Wikipedia: "The small purplish-black fruits, which are quite tart and contain large seeds, are included in smaller quantities in the traditional diets of Pacific Northwest aboriginal peoples, mixed with Salal or another sweeter fruit. Today they are sometimes used to make jelly, alone or mixed with salal. Oregon grape juice can be fermented to make wine, similar to European barberry wine folk traditions, although it requires an unusually high amount of sugar."
Thimbleberry (Rubus parviflorus - Rosaceae).
