Sweet Goldenrod, Solidago chilensis
Sweet goldenrod is a low maintenance native herbaceous perennial wildflower. Growing 2 to 3 feet tall, it has gracefully arching stems of yellow flowers that erupt from basal clumps in the late summer and early fall. It is primarily clump-forming and does not spread aggressively as do some of the other goldenrod species and hybrids.
This wildflower naturalizes well, is drought resistant and tolerates clay soil. It would grow well along a border or in a butterfly, cottage, or herb garden. It is often accused of causing hay fever because it blooms at the same time as some wind-borne pollen plants (like ragweed).
This plant supports Wavy-lined Emerald (Synchlora aerata) larvae. Attractive to bees and butterflies. Members of the genus Solidago also support many specialized bees.
