Dansk: Et tørret eksemplar af Psoralea esculenta (prærieroe) med den runde, spiselige rod nederst. Planten kaldes også hvidt æble (fransk: pomme blanche), jordæble, vild roe, indiansk brødrod (engelsk: Indian breadroot), præriekartoffel, indianerroe, indianerkartoffel samt cree-roe og dakota-roe. Planten blev brugt af mange prærieindianere i supper og på anden vis gennem lange tider. Den blev først kendt viden om, da Lewis og Clark-ekspeditionen (1804-1806) indsamlede et eksemplar. Frederick Pursh beskrev Psoralea esculenta mere grundigt i 1814 i Flora Americae.
English: A dried specimen of Psoralea esculenta (prairie turnip). The round or turnip shaped root was dug up and used as food by a number of Native Americans on the northern plains. Other names for the root are pomme blanche, prairie apple, wild turnip, Indian breadroot, Cree turnip and Dakota turnip. Used by the Natives through centuries, it finaly came to the knowledge of the rest of the world after the Lewis and Clark expedition (1804-1806) collected a specimen. Frederick Purch described Psoralea esculenta at lenght in Flora Americae in 1814.
The root is rich in vitamin C and the content of protein is just slightly lower than the content in corn (maize).
