Velvet-dark petals blaze outward from a warm, honeyed center—Moulin Rouge delivers a dramatic, painterly bloom that seems to glow even in the brightest beds. The flower heads are richly textured, with layered, slightly ruffled rays that hold their color beautifully as they mature, making a striking statement from bud to full face. Grow Moulin Rouge for showy, long-lasting ornamental blooms that invite pollinators to linger all season long.

Frequently Asked Questions


What’s a common pest or disease for Helianthus annuus (sunflower) and how can I control it?
Powdery mildew is a frequent problem on Helianthus annuus, especially in warm weather with humid nights. Start by improving airflow (space plants well) and remove heavily affected lower leaves; for control, spray a labeled fungicide such as potassium bicarbonate or a horticultural soap-based option early when you first see the white dusting. Avoid wetting the leaves and don’t compost diseased foliage so spores aren’t reintroduced to the bed.
How do I know when Helianthus annuus ‘Moulin Rouge’ is ready to harvest?
Harvest when the back of the flower head turns from green to yellow, and the outer petals begin to fade; the head should feel firm and heavy. The seeds develop fully and look plump at maturity—typical timing is around 65 days from sowing for your crop. For best seed harvest, cut the head when most seeds are mature and let it dry upside down in a warm, airy spot until the seeds release easily.
