Goldenrod

Solidago spp.

Goldenrod is a herbaceous perennial known for its bright yellow flower clusters that bloom in late summer and fall. It's primarily an outdoor plant, typically found in fields, meadows, and along roadsides. Goldenrod species vary in height from less than a foot to over six feet. While often blamed for allergies, it's usually ragweed that's the culprit, as goldenrod pollen is heavy and doesn't travel far. People grow it for its late-season color, attracting pollinators, and perceived medicinal properties (though scientific evidence is limited). It is NOT suitable for indoor growing due to high light requirements and size.
