HOW TO GROW

Sowing: Direct sow in late fall, planting the seeds 1/2" deep. For spring planting, mix the seed with moist sand and store it in the refrigerator for 30 days before direct sowing. To start indoors, sow seeds in a flat or individual peat pots, keeping the soil lightly moist and at a temperature of 65-70 degrees F until germination, which usually occurs within 10-20 days. Keep the seedlings moist. When the weather has warmed and the seedlings are well established, transplant outdoors.

Growing: This plant tolerates drought, though it flourishes with regular moisture. It spreads by rhizomes and can be aggressive, especially in moist or rich soil. Plants that are widely spaced or in especially rich soil will reach taller than usual heights, and may need staking or support. This plant attracts bees and butterflies.

Harvesting: For fresh flowers, cut long stems of flowers that have just opened and place them in water immediately; strip the leaves that will fall below the water.

Seed Saving: After their petals drop off, the centers of the flowers will darken and develop tight clusters of seed. Harvest the seed as soon as it ripens, since small birds love to eat it. Cut the heads and spread them out to dry for several days. Thresh the dried heads to separate the seed from the chaff. Store the cleaned seed in a cool, dry place.

DESCRIPTION

Pretty reddish stems and serrated leaves set this native sunflower apart. The flower heads on this perennial are much smaller than domesticated sunflower varieties, but they still produce a crop of sunflower seeds that are quickly consumed by resident songbirds.
Sunflowers were named for their habit of turning their faces to the sun. At the beginning of the development they exhibit heliotropism, or following the sun in its course from east to west, though the mature blossoms usually end up facing straight east. These are said to be the happiest of flowers, and in the language of flowers they symbolize loyalty and constancy.
