This goldenrod was formerly Solidago sempervirens var. mexicana. It is a tall clumping species with tall clusters of yellow flowers. It could be a dramatic accent in the back of a formal flower border. Seedling volunteers can be controlled by removing the faded flower spikes. Numerous specialized bees as well as butterflies and other insect pollinators visit goldenrod flowers. It is reported to be deer resistant. 

It is worth noting that goldenrods do not cause hay fever. Lightweight, air-borne pollen grains of plants like ragweed cause hay fever. Goldenrod pollen is comparatively heavy and sticky. It is moved from flower to flower by insects.
