Similar: Comparing five white-flowered brambles and strawberries, Dwarf Bramble, Rubus lasiococcus, has 3 leaflet-like lobes, not leaflets, as they are rarely divided all the way to the base; Snow Bramble, Rubus nivalis, has small prickles; Strawberry Bramble, Rubus pedatus, has 5 completely separated leaflets; Blueleaf Strawberry, Fragaria virginiana, has 3 leaflets hairless on top, and mostly grows east of the Cascades; Wood Strawberry has 3 leaflets minutely hairy on top;
Natural History: Being the common strawberry of Europe, this is the one served for beaucoup de Euros at Michelin-Four-Star restaurants. Enjoy! Mountain tribes used the leaves and roots as well, mainly as poultices and as antidiarrheal teas.
Commercial strawberries are a complex hybrid derived mainly from two other species native to the Northwest: F. chiloensis of the coastal lowlands, and F. virginiana of the interior. None of them had big berries before the breeding began.
