Product Description

 

Helianthus annuus

|20 Seeds|

 

 This is the tallest variety of a sunflower ever with yellow petals and a dark disc.  American Giant Hybrid grows tall and stays standing long after the others fall. In fact, you may have to literally get out a saw and cut it down at the end of the year. Or leave it through the winter for the birds and squirrels to enjoy the seeds. saves a corner of the garden to pull out all the stops and grow a giant sunflower specimen using all their fertilizer and watering tricks. American Giant Hybrid was developed especially to respond to your best gardening efforts. It is a huge (and we mean, huge) improvement on the old garden varieties that you nursed along in the garden only to see them fall to the ground with the first big wind after flowering. We have seen it grow as tall as 17 feet with a huge 10 inch flower.  Give it space to encourage a huge head! 90 days to maturity from transplant or direct sowing date.

Tips on How to Grow Sunflowers from Seeds

Germination

  • Germination is in  10-15 days at 60- 65°F

  • SOW INDOORS only if you cannot outdoors as stated below.  8-10 weeks before last frost.  Sow one seed 1/2 inch deep per pot. Water and cover with either polythene or bubble plastic to retain the heat, or place pots on a heated bench or in a propagator with the temperature set at 55°F.

  • Remove the covers when the leaves appear. Plant seedlings outside when they are large enough to be handled and the root system is well developed.

  • For Direct Sowing ( DIRECT SOW THIS VARIETY) This variety does not transplant well-

  • Plant outside 1 to 2 weeks after average last frost, and when soil temperature is 65º–75ºF. 

  • Give the plants plenty of room, especially for low-growing varieties that will branch out. Make rows about 30 inches apart. For very smaller varieties, plant closer together, around 12inches apart. You can plant multiple seeds and thin them to the strongest contenders when the plants are 15cm (6in) tall.
  • Transplant seedlings into your garden after the last frost date for your area. When 3 feet tall, thin to 1 plant every 18-24 inches. 
  • Once your plants are established, they should grow well with few problems. Keep the soil moist to slightly dry. Water them during dry periods, once or twice per week. Keep them well weeded, or apply a 2-3 inch layer of mulch for a tidy appearance.
  • Moisture: Very moist for days 1 – 3 or until radicle emergence. On days 4 – 7 reduce moisture to moist . Once actively growing, begin alternating between moisture levels wet and medium .
  • Light: Full sun.
  • Harvesting from seed.
  • To dry sunflower seeds, cut the heads off when they begin to yellow at the back and hang them upside down in a dry location away from rodents and birds. Once dry, rub the seeds off and soak overnight in (1 gallon of water with 1 cup of salt in it.
    Dry in a low heat,  250°F oven for 4 to 5 hours and store in an airtight container. The black-seeded varieties are mainly for oil and birdseed. The grey and white-striped varieties are for drying and eating.
