Growing & Maintenance Tips:

Heliopsis can be grown in either full sun or part shade, but it performs much better in full sun. Soil of average fertility is preferable. When grown in moist, rich soil, it tends to need staking.Growth will be strongest in soil with average fertility and moisture.Deadheading spent flower heads will extend the flowering time and prevent self-seeding. Divide every 2-3 years in spring or fall to maintain vigor.
