Things I didn’t know (one of a series):
The dogwood wasn’t adopted as official state flower until 1941. Before that, the goldenrod and the daisy were considered unofficial state flowers.
According to http://www.netstate.com/states/symb/flowers/nc_dogwood.htm
“National Geographic Magazine listed the daisy as North Carolina’s state flower in April 1917. Indeed, the daisy was a popular flower in the state. Though the July 1936 issue of Flower Grower Magazine cited the oxeye daisy as North Carolina’s state flower, a bill sponsoring the daisy as the official state flower was defeated. The goldenrod was also popularly thought of as the state flower by many in North Carolina but, like the daisy, its abundance throughout the state and its support from garden clubs were not enough to make it official.
“By the end of the 1930s, a movement had gained steam to adopt an official state flower in North Carolina. The daisy, the goldenrod, the dogwood, the flame azalea, the Venus flytrap (Adopted as North Carolina’s official carnivorous plant in 2005) and even the pinecone were among those considered for the honor.
“Because of its abundance throughout the state, the dogwood was able to fend off its most competitive opponent, the flame azalea, at the last minute.”
Jason’s postcard is listed as ca. 1930-45, so technically the Asheville Post Card Co. could’ve designated any darn flower it chose.
