Growing & Maintenance Tips for Heliopsis helianthoides Sundial
Heliopsis performs best in full sun, though it can tolerate part shade. Plant in average, moderately moist soil, as overly rich or wet conditions may lead to weaker stems and the need for staking. Deadhead spent blooms to extend flowering and prevent unwanted self-seeding.
