Solidago houghtonii is often accepted as a distinctive species, but its origins continue to be clouded. It is usually a hexaploid and thought to be a naturally occurring hybrid, but the actual parents are the source of controversy. Potential parents could be S. ptarmicoides, S. ohioensis, and S. riddellii whose offspring then crossed back with another S. ohioensis. Adding to the confusion, the New York populations are slightly different and might add S. uliginosa to their parentage. (Morton 1979; Semple and Ringius 1983; Michigan Natural Features Inventory 1996)

Like many goldenrods, Houghton's is known for its small, bright yellow flowers at the top of an 8-20 inch stem. The flowers are arranged in a flat-topped cluster. The well-scattered leaves are smooth, narrow, 4-5 inches long, and slightly clasping at the base. The fine hairs on the branches of the flower cluster are also distinctive. Flowers appear most frequently in August. (Michigan Natural Features Inventory 1996)
