About Canada Goldenrod
This herbaceous plant is in the perennial plant in the Aster family. It has a central stem that can grow up to six feet tall. It is native to northeastern and north-central North America. The lance-shaped leaves have small teeth or grooves along the margin, otherwise, the leaves are smooth. The stems have lines of white hair and the underside of leaves do not. Several flowering stems emerge from the top of the plant in the form of a panicle with masses of tiny yellow flowers. The plant blooms in late summer and early fall and typically stays in bloom for up to three weeks. The root system is fibrous consisting of creeping rhizomes that cause this plant to grow in clusters sometimes forming dense colonies. Canada goldenrod prefers sunny locations and grows almost everywhere from roadsides to fields and meadows, woodlands and both cultivated and vacant fields.
