Yellow sweetclover is a vigorous, fast-growing biennial or short-lived perennial that thrives in full sun and tolerates poor, dry soils with ease. It produces tall spikes of fragrant yellow flowers that are highly attractive to bees and other pollinators throughout summer. Be mindful of its self-seeding habit, as it can spread readily — deadhead before seed set if you want to limit its spread.
