From mid- or late summer into fall, these eastern U.S. natives enliven the garden with large, branching clusters of small bright yellow flowers. Blossoms are carried on leafy stems that rise from tough, woody, spreading rootstocks. Leaves are narrow, generally linear to lance shaped.
Goldenrods are not as widely grown as they deserve to be, largely due to the mistaken belief that their pollen causes hay fever (in fact, other plants are responsible). All are tough plants that thrive in not-too-rich soil. Use in informal borders or naturalize in meadows.Solidago hybrids
