About Sunflowers

Sunflower (Helianthus annuus) is an annual plant with a large daisy-like flower face. Its scientific name comes from the Greek words helios (“sun”) and anthos (“flower”). Sunflowers trace their history to plants found at archeological sites dating from 3,000 BC. Sunflowers were first purposely cultivated by Native Americans in the Southwest or Mississippi River valley area as a source of medicine, fiber, seeds, and oil. When the European settlers arrived, they recognized it's value, and they sent the seeds back to Europe. 
Growing sunflowers is an easy and a funny way to add a burst of color to your garden.
There are many varieties of sunflowers available today, so there’s always one that fits your garden, you can choose your favorite variety that fit your garden from HERE!

When to Grow Sunflowers

Sunflowers grow best in locations with direct sunlight about 8 hours per day.
Sunflowers can be started indoors in individual peat pots, but it is easiest to sow the seeds directly into the soil after all danger of spring frost is past. If your growing season is short, you can safely plant the seeds up to 2 weeks before the last expected spring frost. If your growing season is long, it is best to wait until the soil temperature reaches about 60 degrees to plant outdoors.

Downy Mildew causes mottling and pale areas on upper leaf surfaces and a fuzzy mold growth on their undersides. Eventually these leaves wither and die. Always the oldest leaves are usually infected first, but don't worry, downy mildow will not kill a mature plant.

Rust appears on upper leaf surfaces first as yellow or white spots that turn brown or black. The disease may spread to stems and flowers, causing distorted growth.

How to Harvest Sunflower Seeds

When the season is over, you can harvest sunflower seeds for a tasty snack, to feed the birds in the next winter, or to plant next season. Remember that the plants from which you harvest the seeds must be healthy and vigorous. As this will help ensure good quality seedlings and plants.

  • Let the flowers dry until the back of the head turns brown, the foliage turns yellow, the petals die down, and the seeds look plump.
  • With a pruner, cut the head off the plant about 5 inches below the flower head. 
  • To remove the seeds, simply rub your hand over the seeded area and pull them off the plant. 
  • Birds and squirrels enjoy when seeds ripen and harvest time approaches. So I have many seeds, you can leave some, as it is fun to watch them enjoy the bounty!

Saving Sunflower Seeds

  • If you're saving the seeds for the next growing season, you can store them in an airtight container in a cool, dry place until next year. I always keep the container at room temperature and away from excess heat, light and moisture to extend the shelf life of my seeds.
  • Label the container with the variety and the date you harvested.
  • Sunflower seed will last for years if stored this way. But keep in mind that seed viability depends on the condition of the seed when first stored, how long it is stored!
  • If sunflower seeds has been saved for a long time, more than 3 years, you may wish to test a sample of seeds to see if they will still germinate well. If you have good germination rate, yours seed are still good.
Sunflowers are low maintenance, fast-growing plant, and so beautiful.
