Early Goldenrod (Solidago juncea) is a great choice for a sunny, well-drained pollinator garden. This plant blooms earlier in the season than other goldenrods and can be deadheaded to extend its blooming time.
Goldenrods are keystone species that support many pollinators as both nectar sources and host plants. They are larval host plants to dozens of moth species including the Wavy-lined Emerald (Synchlora aerata) and many specialized mining bee species (Family Andrenidae). Goldenrods are often falsely blamed for causing seasonal allergies; the real culprit is ragweed (Ambrosia spp.), which flowers at the same time.
