Helianthus maximiliani
This native perennial sunflower relative begins blooming in August and continues well into the fall until the first frost. It attracts a large spectrum of bees, butterflies, and moths. The leaves host the larvae of the Silvery Checkerspot and the Gorgone Checkerspot. We’ve witnessed many song birds feasting on the seeds of this plant on the farm. It is actually considered to be one of the best perennial wildflowers for birds. Similar to Jerusalem Artichoke, its tubers are edible and can be roasted or shredded into a salad. The seeds are edible as well and can be eaten raw or pressed for oil. It reaches high for the sky and can spread with its rhizomes. Be conscientious of where you plant it.
