|Rubus spectabilis subsp. var.||Salmonberry|
Rubus spectabilis (Salmonberry) is a species of Rubus native to the west coast of North America from northwestern Alaska (e.g. Unalakleet, AK) to California.
It is a shrub growing to 1–4 m tall, with perennial, not biennial woody stems (unlike other species). The leaves are trifoliate, 7–22 cm long, the terminal leaflet larger than the two side leaflets. The leaf margins are toothed. The flowers are 2–3 cm diameter, with five purple petals; they are produced from early spring to early summer. The fruit matures in late summer to early autumn, and resembles a large yellow to orange-red raspberry 1.5-2 cm long with many drupelets.
In the Pacific Northwest of North America the berries can ripen from mid-June to late-July.
Salmonberries are found in moist forests and stream margins, especially in the coastal forests. They often form large thickets, and thrive in the open spaces under stands of Red Alder (Alnus rubra).
Salmonberries are edible and share the fruit structure of the raspberry, with the fruit pulling away from its receptacle. Books often call the fruit "insipid" but depending on ripeness and site, they are good eaten raw and when processed into jam, candy, jelly and wine.
It is widely grown as an ornamental plant for its flowers. A double-flowered form was discovered in at the mouth of the Duckabush_River, Jefferson County, Washington around May 1, 1961, by Dr. R. C. Creelman of Bremerton, Washington. This has been given the cultivar name 'Olympic Double' or 'Olympic'.    Another double salmonberry was found by Phyllis Munday of Vancouver BC, but neither the date nor the site has been determined. This double may be confused in gardens with 'Olympic Double'.
