Fruit: the fruit are smooth and dry seeds that have a soft, fluffy brown pappus (tufts of hair) which allow the seed to be dispersed by the wind.

Landscape: a strong standing, adaptable plant that provides brilliant, bright yellow flowers for the fall season. It is an important source of nectar for butterflies and bees in autumn.  One of our highest recommended plants for your perennial garden.  

Comments: there is a lot of variability in the appearance of showy goldenrod with at  two subspecies being recorded in Northwest Indiana.  Goldenrods are not a source for ragweed pollen.

Etymology: The epithet name speciosa is Latin for "brilliant, showy, spectacular" because of the spectacular nature of the plant. The genus, solidago, comes from the Latin word, solida meaning "whole" and ago meaning "to make".
