Plant notes

Yellow flower spikes bloom on plants that filled in well and many insects, including locust borer, were seen at it. Plants bloomed throughout September. This species was the seventh most attractive to natural enemies in the late season, with three times as many natural enemies as the grass control.

Habitat

Showy goldenrod grows in full to partial sun, and very dry to average soil moisture. It naturally occurs in dry, open, sandy areas including prairies, field, and oak and jack pine savannas. It may be found along roadsides and railroads, and also occurs in the Upper Peninsula in thin soil on high rock mountains.

Cultivation and management

This plant can be grown from seed (flowers in third year) or plug material (flowers in second year). Riddell?s goldenrod (Solidago riddellii) was also tested for attractiveness to natural enemies and attracted more natural enemies and fewer pests than showy goldenrod (S. speciosa). Showy goldenrod, however, is better suited to dry sites than Riddell?s goldenrod. Although Canada goldenrod (Solidago canadensis) may become an agricultural pest, neither showy or Riddell?s goldenrod are known to be.
