Midnight Rouge Sunflower, (Helianthus annuus ‘Midnight Rouge’)

Unlike the traditional golden sunflowers, Midnight Rouge captivates with its rich, moody tones that add a dramatic flair to any landscape or floral arrangement.

Height: Typically reaches 5–7 feet tall

Blooms: Single or branching stems bearing multiple 4–6 inch blooms

Petals: Dark red to nearly black with a mahogany sheen

Center: Dark brown to black seed disc

Foliage: Coarse, broad green leaves

Growth Habit: Upright and branching; ideal for borders or cutting gardens

This variety is pollen-rich, making it a favorite among pollinators like bees and butterflies, and it also produces edible seeds, making it both ornamental and functional.

🌿 Historical and Fun Facts
Historical Roots: Sunflowers are native to North America and were cultivated by Indigenous peoples over 4,000 years ago for food, oil, dye, and ceremonial purposes.

Name Origin: The name Helianthus derives from the Greek helios (sun) and anthos (flower), referring to its heliotropic nature (turning toward the sun).

Modern Cultivar: Midnight Rouge is a relatively modern hybrid bred for ornamental and cut flower use, reflecting modern preferences for dramatic and moody garden palettes.

Fun Fact: Though their colors are dark, Midnight Rouge sunflowers are just as attractive to bees as their golden counterparts. Their petals absorb heat, which can even help pollinators warm up in cooler morning temperatures.

Trowel or hoe

Garden marker or stake (for spacing or labeling)

Mulch (optional, for moisture retention)

Water source (hose or watering can)

Full sun location (6–8 hours/day minimum)

🌻 Detailed Steps to Grow from Seed
Prepare the Soil:

Choose a sunny, well-drained spot.

Amend soil with compost or aged manure to enrich nutrients.

Planting Seeds:

Sow directly outdoors after the last frost.

Plant seeds ½ to 1 inch deep and 12–18 inches apart.

Water gently but thoroughly after planting.

Seed Preparation (optional):

Soak seeds for 6–8 hours in lukewarm water before planting to improve germination rates (especially in cooler soil).

Maintenance:

Water regularly during dry periods, keeping the soil consistently moist but not soggy.

Mulch to retain soil moisture and suppress weeds.

Stake taller plants or those exposed to wind.

Fertilization:

Use a balanced organic fertilizer once or twice during the growing season if the soil is poor. Avoid high-nitrogen formulas, which reduce blooming.

Harvesting:

Cut blooms for vases when petals begin to unfurl.

To harvest seeds, allow flower heads to dry on the plant until the back of the head turns yellow/brown and seeds loosen easily.

Cover seed heads with mesh or paper bags if birds become a problem.

🌼 Special Precautions
Watch for Pests: Common pests include aphids and caterpillars; treat organically with neem oil or insecticidal soap if needed.

Avoid Overwatering: Sunflowers are drought-tolerant once established and dislike soggy soil.

Deadheading: Not required but can prolong bloom period and prevent self-seeding in ornamental areas.

✂️ Ornamental Uses
Cut Flowers: Excellent in bouquets and floral arrangements due to long vase life and striking color contrast.
