Elecampane

Inula helenium. One of the most highly regarded herbs of the Western herbal tradition and a very important part of the Pacific Northwest apothecary. Plus, a returning perennial with pretty yellow flowers! Full sun to part shade. Clumping form that will grow to 5-6’ tall and return every year so plant towards the back of your perennial beds (not in an annual garden bed).
 
The roots of elecampane are used for many ailments, especially respiratory issues including bronchial infections and chronic cough. The root is harvested in the autumn of the second year.
