Leaves used as fermented tea. The plant is not considered palatable, but the young shoots and leaves can be cooked and eaten. [13] [14] Fresh leaves can be eaten raw. [2] The young flowers are also edible (being made into jelly in the Yukon) [15] and the stems of older plants can be split to extract the edible raw pith. [16]
