Showy Sunflower Seeds

Helianthus laetiflorus

  • HOW TO GROW
  • FAST FACTS

HOW TO GROW

Sowing: Direct sow in late fall, planting the showy sunflower 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 showy sunflower 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. This plant adapts well to clay soil.

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. Deadhead the flowers for prolonged blooming. Plants growing in partial shade or moist 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: This Helianthus Laetiflorus plant is a hybrid and will not produce viable seed.

DESCRIPTION

Unlike domesticated sunflowers, this native sunflower is a perennial and will come back year after year. This wildflower features bright yellow petals and dark centers, which are much smaller than annual sunflowers.
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.
