The Use and Cultivation of Goldenrod Flower

Parts of some goldenrods can be edible when cooked. Goldenrod is also used as a food plant by the larvae of various Lepidoptera species (see list of Lepidoptera that feed on goldenrods). The invading larva induces the plant to form a bulbous tissue mass (called a gall) around it, upon which the larva then feeds. Various parasitoid wasps find these galls and lay eggs in the larvae, penetrating the bulb with their ovipositor. Woodpeckers have adapted to peck open the galls and eat the insect in the center.

Goldenrods can be used for decoration and making tea. Goldenrods are, in some places, held as a sign of good luck or good fortune; but they are considered weeds in others.

Goldenrods are mostly short-day plants and bloom in late summer and early fall and some species produce abundant nectar when moisture is plentiful before bloom, and the bloom period is relatively warm and sunny. Honey from goldenrods often is dark and strong due to admixtures of other nectars. However when there is a strong honey flow, a light (often water white), spicy-tasting honey is produced. While the bees are ripening the honey there is a rank odor and taste, but finished honey is much milder.
