Ranunculus pennsylvanicus (common name: pennsylvania buttercup) is a forb with yellow flowers that prefers moist loamy soil[1] and grows in meadows, alluvium, and ditches[2] across Canada and Alaska and as far south as Colorado. The leaves are edible as a famine food when cooked to remove a heat sensitive toxin.[3][4][5][6][7][8][9]
Juice from this plant is strongly acrid and is a rubefacient[10] that is used to raise blisters.[10]
Propagation: Seed - sow spring in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer.
A greedy plant, inhibiting the growth of nearby plants, especially legumes[11].
Usage: The entire plant can be boiled to yield a red dye[12]. It is mixed with the bark of bur oak to set the color.[12]
The entire plant can be boiled with rushes (Juncus spp) or flags (Iris spp and Acorus calamus) to colour them yellow for use in making mats, baskets etc[12].
