In Europe, there are not as many species, and when first imported into England from the Middle East, it was an expensive medicinal herb. Its Latin name of Solidago means to make whole, or heal. Solidago was believed to cure kidney ailments, and a compress relieved the pain of fresh wounds and insect stings. Early herbals list a long litany of ailments goldenrod could cure, including calming the nerves. It also had a sweet taste used to hide more unpalatable medicines. Today, medical research has not proved goldenrod capable of curing anything except maybe blah spirits when someone looks at its cheery plumes of tiny yellow flowers.
Goldenrod still has some uses. Weavers use the flower heads for a natural dye. It provides varying tones of yellow depending on how the dye is made. Its dried flower heads provide winter bouquets, keeping their yellow color in a much softer tone. The only other notable use of goldenrod was in 1948, when Texas tried to develop it as an agricultural crop for an ingredient in goldenrod gum and candies. They didn't succeed.
For many years goldenrod suffered an undeserved reputation for causing hay fever. Insects pollinate goldenrod, so its pollen is large and sticky to make it easier to coat the insect body for pollinating the next flower. This makes the pollen heavy and more likely to drop to the ground than become air-borne.
European gardeners think of goldenrod as an important garden plant and have developed many cultivars and hybrids. These have been exported back to the United States and are now commonly available in nurseries. The hybrids have been dwarfed, and the coarse stems and foliage somewhat refined to produce better garden plants. 'Golden Thumb,' also known as 'Tom Thumb,' is about twelve inches tall. Other cultivars that grow about twenty-four inches are 'Baby Gold,' 'Golden Baby,' and 'Golden Gates.'
I still like mine best in the surrounding fields.
