Solidago altissima

Common Name(s):
Canada goldenrod, Canadian goldenrod, late goldenrod, tall goldenrod
Native Plants, Perennials, Wildflowers

This perennial wildlfower is in the Asteraceae, or sunflower family.  It has erect,  2-6 ft. stems that occur either singly or in clusters. Stems are covered in narrow green hairy leaves that are between 2.5-3.5 inches long.  Small, dark yellow flowers form a plume-like feathery inflorescence.  It produces alleleopathic compounds, or chemicals that suppress the growth of other plants and it can become weedy.  

Bees, butterflies, and beetles, especially flower (soldier) beetles (Chauliognathus) are strongly attracted to the nectar-rich flowers

Although goldenrod is often blamed for hayfeaver because it is in bloom during that season, ragweed is the likely culprit.  It does well in soils disturbed by humans.
