This unique hybrid sunflower was bred for the florist market. It has very uniform shape and size with big flat discs and evenly radiating, bright yellow petals on strong stems for excellent cut flowers. The flowers produce nectar that is attractive to bees and other pollinators, but no pollen is produced. That means no mess beneath a vase of cut flowers. Jerusalem Gold Organic sunflowers also produce good sized black seeds. The plants are about 1.6 meters (5.5′) tall with (usually) only one flower each. Plant Jerusalem Gold Organic sunflower seeds to attract pollinators to your organic vegetable garden, and then leave the seeds on the plants for chickadees and other wild birds to forage on.
Size: 1g (approx. 21 seeds)

Season & Zone
Exposure: Full sun
Sow seeds 5mm-1cm (¼-½”) deep. Space dwarf varieties 15cm (6″) apart, but give the giants lots of room at 1m (3′) between plants.
To grow really big plants with really big flowers, enrich the soil with organic matter and incorporate 2 cups of balanced organic fertilizer per 3m (10′) of row, and irrigate regularly. When the plants are 30cm (12) tall, dissolve 5ml (1 tsp) of borax (for boron) in 350 ml (12 fl oz) of water and spread the solution over 5m (15′) of row. Be careful not to over-apply this solution. This application of boron will produce bigger seeds and flower heads. Do not apply boron to other garden plants. When the back of the flower head turns yellow, it is ready to be cut from the plant.
Sunflowers planted near rows of corn are said to increase yields. Sunflowers can be used to draw heavy metals, toxins, and even radiation from soil, but should be burned at the end of the season if grown for this purpose. Plant sunflowers amid squash plantings to improve pollination and overall production.
