Making Car Tires from Goldenrod?

Making It Grow Radio Minute
SC Public Radio

Here’s a fun fact about goldenrod which is coming into bloom across the states. According to the A C Moore Herbarium, over thirty species of goldenrod, the genus Solidago, have been collected in South Carolina, some grow all over the place while others occur in just a few counties When rubber was difficult to get during World War One, Henry Ford asked Thomas Edison to find a plant native to the US that could be used for rubber production so he could have tires for his cars. Surprisingly, goldenrod turned out to be the solution. As our roadsides make obvious, goldenrod is really easy to grow and can yield decent amounts of latex when processed. But cheaper synthetic rubber came on the market and our farmers grow fields of fluffy white cotton instead of fields of gold.
