This tall, stately native biennial creates a low rosette in its first year, then sends up a spike of yellow flowers in the second year and flowers, dying in the fall of that year. Reseeds enthusiastically; goldfinches relish the seeds. Attractive in the back of plantings or against a fence. The large taproot helps aerate clay soils.
