Western skunk cabbage is a large, dramatic wetland plant with bright yellow flower spikes that emerge before massive paddle-shaped leaves unfold in spring. This moisture-loving perennial creates bold texture in wet areas but requires consistently saturated soil and cool conditions. The plant gets its name from the strong odor it releases when damaged or disturbed.
