Helianthus annuus (hybrid)
‘Rouge Royale’ is a stunning, true red sunflower, on multi-branching plants. A dramatic accent in beds, borders, and arrangements. For highest quality cut flowers, planting closer together will produce longer stems and smaller flowers. For long-lasting vase life, cut before flower is completely open. ‘Rouge Royale’ doesn’t drop its pollen making it all beauty and no mess. Drought tolerant once established. Botanical Interests’® Rouge Royale Sunflower Seeds have been verified by The Non-GMO Project.
Outdoors: Sow 1-2 weeks after your average last frost date.
Indoors: Sow 2-4 weeks before your average last frost date. Sunflowers are sensitive to root disturbance, so sow in biodegradable pots that can be planted directly in the ground.
