Frequently Asked Questions


Why are my Helianthus annuus (sunflower ‘Velvet Queen’) leaves turning yellow or developing spots, and what should I do?
Look for fungal leaf spots (dark brown/gray spots with yellowing) and treat early with better airflow: thin crowded plants and water at the soil line, not the leaves. If new spots keep spreading, spray a labeled fungicide for edible/non-edible sunflowers per the product directions, especially during humid stretches.
How often should I water Helianthus annuus during the main growing phase?
During active growth (after emergence until heads form), keep the top 1–2 inches of soil evenly moist, then water deeply when it starts to dry out at that depth. Aim for roughly 1 inch of water per week as a baseline, increasing during hot spells; sunflowers tolerate brief dryness but consistently wet soil encourages disease.
How can I tell when Helianthus annuus (‘Velvet Queen’) is ready to harvest at about 70 days?
Harvest when the back of the flower head turns yellow to deep brown and the bracts (the small leaf-like parts around the head) loosen. The seeds should look plump and filled; cut the stems and let the heads dry in a warm, airy spot until fully dry before removing seeds.
Botanical illustration of Velvet Queen

Velvet Queen blooms with a truly velvety presence—sun-warmed petals in rich golden tones that seem to glow from within, framed by a deep, dark center that reads almost ink-black at a distance. The flower heads are bold and well-proportioned, with a lush, full texture that holds its beauty through the season and invites pollinators to linger. Grow Velvet Queen for striking, long-lasting color in the garden beds and borders, and enjoy the steady parade of blooms from early summer into fall.

Sowing Tips

Transplant Conditions

Wait until soil reaches 55°F and nights stay above 40°F before moving outdoors.

Expert Note

Sow in place after frost or when soil is warm, keep moisture steady until seedlings establish, and thin to the strongest plants for best bloom.
