Solidaga rigida, stiff goldenrod, has some of the largest individual flowers of the genus – up to ½” in diameter. A native perennial to 5’ x 2.5’ whose flat topped inflorescence (group of flowers) are frequented by butterflies and birds (once the seeds are ripe), this plant thrives in full sun average soils. The gray green leaves in summer age to a dusky rose color in autumn. Gardeners may want to deadhead the flowers to discourage this plant from becoming weedy. Free of major insect and disease problems and not a favorite of deer. The correct scinetific name for this is now Oligoneuron rigidum.
