Sunflower Seeds:

The sunflower (scientific name: Helianthus annuus) is a popular solar plant and the national flower of the United States. It belongs to the Compositae family and is an annual herb.
The sunflower seed is its most famous and important part. These seeds are flat, ovoid, and usually dark brown or taupe. The surface of the seeds is smooth with distinct longitudinal stripes. Their size and shape vary from species to species, generally around 0.5 cm in diameter.
Sunflower seeds are packed with nutrients and are an important food source for humans and many animals. They are rich in protein, fiber, vitamin E, vitamin B complex, zinc, magnesium, copper and other trace elements. People can eat these seeds directly or process them into foods like oil and biscuits.


In addition, sunflower seeds are widely used for planting. One can buy sunflower seeds and plant them in the right season and environment. These seeds germinate quickly and grow quickly, making them popular in gardening and agriculture. Sunflowers are also often used as ornamental plants, and their huge yellow flowers and tall stems bring beauty and visual enjoyment to people.
Overall, sunflower seeds are a nutritious and versatile plant product that can be used both as food and as planting and ornamental material.

How to Sow and Plant
Sunflowers are grown from seed sown directly in the garden after frost.

Direct sow seeds in average soil in full sun after all danger of frost.
When choosing a site consider that sunflowers need a well-drained soil.  They face the sun, so make sure they are in an open area of the garden. The taller varieties will cast shadows on other plants, so plant these at the north end of your garden.
Prepare the soil by removing weeds and working organic matter into the top 6-8 inches of soil; then level and smooth.
Most plants respond well to soils amended with organic matter. Compost is a wonderful form of organic matter with a good balance of nutrients and an ideal pH level, it can be added to your planting area at any time. If compost is not available, top dress the soil after planting with 1-2 inches of organic mulch, which will begin to breakdown into compost. After the growing season, a soil test will indicate what soil amendments are needed for the following season.
Sow seeds ½ inch deep in groups of 2 or 3 seeds. Space the groups 18-24 inches apart, depending on the variety.
Firm soil lightly, water and keep evenly moist. 
Seedlings will emerge in 7-10 days.
Thin to one plant per group when seedlings have two sets of leaves.

How to Grow
Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating. 
Mulches also help retain soil moisture and maintain even soil temperatures. For annuals an organic mulch of shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time. Always keep mulches off a plant’s stems to prevent possible rot.
Keep soil evenly moist but not wet.
Once established sunflowers can tolerate drought.
No fertilizer is needed unless the soil is poor. Do not over fertilize.
Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
Some varieties only produce one bloom so once the bloom is spent, the plant may be removed.
Remove plants after they are killed by frost in fall to avoid disease issues the following year.

Tips
Edible sunflowers will mature in about 3 months or more after sowing. To harvest the seeds, cut the heads off after the stalks are quite dry but before fall or winter rains come. Check the flower heads for maturity to see if the florets in the center of the flower disk have shriveled and the back of the flower head is turning yellow, or the head is starting to droop. Cut flower-heads with a foot of the stalk attached. Hang heads in a warm, dry, well-ventilated place so the seeds may fully ripen and dry. Cheesecloth, netting or a paper bag with holes punched in for ventilation should be placed over the head to protect the seeds and to collect those that may drop from drying.
Shorter varieties may be grown in containers. Be sure to use a commercial potting mix.
Pollenless varieties make terrific cut flowers.


FAQs
What direction do the flowers face? Sunflowers follow the sun.

Are any of the seeds toxic? No, they are not toxic, however only the giant sunflower seeds are good for eating.

Why are the seeds hollow? This could be from a lack of pollination, sunflowers need insects for pollination. Also sunflower moth larvae may leave tiny holes in the shell.

How many flowers does each stem of the giant flowers get? One.

How long do sunflowers bloom? Sunflowers bloom for about 4-6 weeks.
