General Information:
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.
Plant Care:
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. Cut back by one-half in early to midsummer to prevent staking.
