Comprehensive Description

Read full entry
This is the most common and weedy goldenrod in Illinois. The flowers are especially attractive to many species of wasps and flies, which play an important role in controlling insect pests, or breaking down organic matter in the detritus cycle. The species Solidago altissima (Tall Goldenrod) is now considered a variety of Canada Goldenrod, rather than a separate species. It has been reported that the foliage of the typical species contains a volatile oil that chemically resembles the oil from pine needles. A close-up photograph of the inflorescence will be revealed if the mouse curser is placed over the upper photograph.
