Goldenrod, Subbing for the Rubber Plant?
Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. You might enjoy hearing some fun facts about goldenrod since it’s blooming everywhere now. Carolina’s AC Moore Herbarium lists over thirty different species of goldenrod, in the genus Solidago, collected here; some grow all over while others occur in only a few counties. Our state wild flower is Solidago altissima, sometimes listed as Solidago canadensis. According to the Sciway website, when rubber prices skyrocketed during World War I, Henry Ford asked Thomas Edison to find a native plant that could yield a substitute so he could keep manufacturing tires and such. Lo and behold, our ubiquitous goldenrod was the answer. As our roadsides and fields make obvious, goldenrod is easy to grow and can actually yield lots of latex when processed. But cheaper synthetic rubber came on the market and so our farmers grow fluffy white cotton instead of fields of gold.
