Majestic, multi-branched plants provide gorgeous cut flowers throughout summer. Easy to grow in almost any well-drained soil, and drought tolerant. In areas with a long growing season, sow a new crop every 2–4 weeks up until 3 months before first fall frost for continuous bloom. Due to its intense bee attraction, 'Lemon Queen' is the sunflower used in the Great Sunflower Project, a study to gather information about native bee populations.
