(Helianthus annuus) Multi-headed flowers range from bright yellow to
gold to dark burgundy, with some bi-colors. Under
ideal conditions one plant can have up to two dozen
flowers blooming at the same time. Very nice for
cutting. Plants grow 5-8' tall. Annual, 60 days.
Green Thumb Tip Sow seeds outdoors after last frost. Sunflowers
prefer full sun to light shade and well-drained rich
soil. Provide support for tall plants.
