Fun facts: Goldenrod contains a substance that produces rubber, and Thomas Edison grew very tall Goldenrod and used it to make rubber! Henry Ford used it to make the tires for his Model T car too!
Also, Goldenrod is not typically allergy producing even though it gets blamed for it. It's not ragweed which is allergenic, but it often grows in proximity so it gets lumped in as a culprit. The young leaves are edible. North Americans used it in Herbal remedies for toothaches.
