Helianthus add structure to the summer border. Performs right thru August when other perennials rest. Plants are carefree in full sun. Finches flock to the dry seed heads. Idaho has restricted all potted plant material from being shipped into Idaho at this time.
Prefers average, neutral to slightly alkaline soil. Well-drained soil is good for overwintering, but give Helianthus a good soaking if August begins to overpower. Can be divided in spring every 3-4 years.
