Stiff goldenrod (Oligoneuron rigidum, formerly known as Solidago rigida) produces the small, bright yellow blooms you expect from a goldenrod, but its foliage and flowering form set it apart from the crowd. The blunt-tipped leaves are covered with short hairs, giving them a velvety grayish green appearance, and the 4- to 5-foot-tall stems branch only at the top into distinctly broad, flattened to somewhat domed clusters instead of the usual plumes of most other goldenrods.
Stiff goldenrod shares many of the good qualities of its relatives, producing a splendid show of abundant late summer-into-autumn flowers that provide a wealth of nectar and pollen for bees, butterflies, and other insects, as well as lots of seeds for birds. The plants may also develop some reddish fall color. They tend to stay in clumps but can self-sow from seeds the birds miss, so you may want to keep this species for a meadow or “wild garden” with other sturdy flowering perennials and ornamental grasses. Consider it for a cutting garden too; it’s a beautiful addition to fall arrangements. This widely adapted U.S. native is also known as rigid goldenrod or stiff-leaved goldenrod. Full sun. Perennial; Zones 3 to 9.
Collected in late October 2020. At least 20 seeds.
