Here's a guide to planting sunflower seeds (Helianthus annuus) in the USA, covering both direct sowing and starting seeds indoors:

Site Selection
Sunlight: Sunflowers thrive in full sun, needing at least 6-8 hours of direct sunlight daily. Choose a sunny spot in your garden.  
Soil: Sunflowers prefer well-drained soil. They can tolerate various soil types but will do best in fertile, loamy soil.  

Soil Preparation
Amendments: Before planting, improve your soil by adding compost or well-rotted manure. This will provide nutrients and improve drainage.  
pH: Sunflowers prefer a soil pH slightly on the acidic side, ideally between 6.0 and 6.8.  
Planting

Direct Sowing (Fall or Spring)
Timing:
Fall: In warmer climates, you can sow seeds in the fall for blooms the following spring.
Spring: The most common time to plant sunflowers is in the spring, after the last frost has passed.  
Depth: Plant seeds about 1 inch deep.
Spacing: Space seeds about 6 inches apart for smaller varieties and 1-2 feet apart for larger varieties.

Starting Seeds Indoors (Spring)
Timing: Start seeds indoors 3-4 weeks before the last expected frost in your area.
Containers: Use biodegradable pots to avoid disturbing the roots when transplanting.  
Depth: Plant seeds about 1 inch deep.  
Light: Provide ample light for seedlings. A sunny window or grow lights work well.

Watering
Keep the soil consistently moist until seeds germinate and seedlings are established.
Once established, sunflowers are relatively drought-tolerant but will benefit from occasional deep watering, especially during hot, dry periods.

Stratification and Scarification
Stratification: Sunflowers do not require stratification (a period of cold dormancy) for germination.  
Scarification: Scarification (scratching or nicking the seed coat) is not necessary for sunflower seeds.

Maintenance
Thinning: Once seedlings have a few sets of true leaves, thin them to the recommended spacing.
Weeding: Keep the area around sunflowers free of weeds, especially when they are young.
Support: Taller varieties may need staking to prevent them from falling over, especially in windy areas.  
Fertilizing: Sunflowers are heavy feeders. Apply a balanced fertilizer when plants are about 2 feet tall.  

Invasiveness
Sunflowers are not considered invasive in most of the USA. They are annuals, meaning they complete their life cycle in one year and do not spread aggressively.  

Additional Tips
Pest and Disease Control: Watch for common sunflower pests like sunflower moths and birds. Protect seeds and young plants with netting if needed.
Succession Planting: To extend the blooming period, sow seeds in batches every few weeks.  
Harvesting Seeds: If you want to harvest sunflower seeds, allow the flower heads to mature fully and turn brown.
