Solidago canadensis

Description

Canada Goldenrod is a native perennial plant in the daisy family that is found in much of Canada and the USA except for the southernmost SE states. Due to its wide distribution, there are several varieties causing variation in the size, leaf and flower description. It has branching pyramid-shaped cascading clusters of small yellow flowers that appear in late summer into fall.  It is not related to ragweed that causes allergy symptoms. Goldenrods spread by seed and rhizomes and are considered weedy by some.

Use this plant in naturalized areas or meadows, in pollinator gardens and native gardens. It prefers a soil with some clay and moist but not wet conditions in full sun. Bees and butterflies are attracted to the flowers.

Problems: rust (Coleosporium asterum), powdery mildew, and leaf spot. Insect pests include aphids, beetles, and gall-forming insects.
