WaterFalse sunflowers need moderate watering and prefer consistent moisture, especially during their growing season. They should be watered deeply once a week to encourage root development, providing about one inch of water which is roughly equivalent to 0.6 gallons per square yard of soil area. During hot or dry spells, watering frequency may need to increase to twice a week. It is important to avoid overhead watering to prevent disease, instead use a drip system or water at the base of the plant. Be careful not to overwater, as they are somewhat drought tolerant and excessive water can lead to root rot.
LightFalse sunflowers thrive best in full sun, which means they need at least six hours of direct sunlight daily. The ideal spot for them is an open area with clear exposure to the sun, without shade from trees or buildings. They can tolerate partial shade but will produce fewer flowers and become lankier in less light.
TemperatureFalse sunflowers are hardy and can tolerate a wide range of temperatures. The ideal growing conditions are between 60°F and 75°F. They can survive minimum temperatures down to -30°F, which are conditions typical of a USDA hardiness zone 3. These plants can also cope with temperatures well into the 90°F range during summer months without significant stress.
PruningPruning false sunflowers can promote bushier growth and encourage more blooms. Deadheading, or removing spent flowers, will prevent them from going to seed and stimulate a second flush of blooms. Pruning can be done throughout the blooming season as needed. The best time for significant pruning is in late winter or early spring before new growth starts.

Life cycle'Summer Nights' false sunflower, or Heliopsis helianthoides var. scabra 'Summer Nights', begins its life cycle with seed germination, which occurs in late spring after the last frost when soil temperatures warm sufficiently. Following germination, seedlings emerge and develop into young plants with a rosette of leaves at the soil surface. The vegetative stage is marked by rapid growth as the plant develops a sturdy stem and broader foliage, preparing for the flowering phase. Flowering typically takes place in the early to mid-summer, producing distinctive deep yellow to orange flowers with a contrasting mahogany center, attracting a variety of pollinators. After pollination, the flowers develop into achenes (a type of dry fruit), which mature by late summer or early fall and are then dispersed, completing the reproductive stage. Finally, as a perennial, the plant's aboveground structures die back with the onset of winter, while the root system enters a period of dormancy before resuming growth the following spring.
PropogationPropogation time
Spring-Early Summer
Heliopsis helianthoides var. scabra 'Summer Nights', commonly known as the False Sunflower, is most effectively propagated by division. The best time to perform this method is in the early spring or fall when the plant is not actively blooming. To propagate by division, carefully dig up the plant, ensuring a generous amount of roots are attached. Then gently separate the clump into smaller sections with at least two or three shoots each. Replant these divisions immediately, maintaining a distance of about 18 inches (approximately 45 centimeters) between the new plants. Water them thoroughly to help establish the newly divided plants in their locations. This method allows the gardener to have fully mature and blooming specimens much sooner than starting from seed.
