Wild Sunflower (Helianthus Annuus) - Imagine a meadow filled with wild Sunflowers! These giant annuals produce numerous 3 - 6 inch flower heads on branching stems. They are native to dry plains, prairies, meadows and foothills in the western United States, Canada and northern Mexico. The plants are coarse, hairy, leafy, and fast-growing and typically grow to 36 - 108 inches tall with stiff branching, upright stalks. The species is commonly seen growing along roads, fences, fields and in waste areas west of the Mississippi River and is the state flower of Kansas. The flower heads have orange-yellow petals and brown to purple center disks. Planting wild Sunflower seeds will create a lovely naturalized setting.

Grow wild Helianthus in a sunny location in somewhat fertile well-drained soil. Keep soil weed free and moderately moist while plants are young. Once established, the plants are somewhat drought and heat tolerant. They will flower mid-summer through fall. Birds are attracted to the seeds.

Wild Sunflower seeds require a cold treatment. First, Sow seed in a moisten soil-less growing medium like peat moss, then enclose in plastic bag or small container and place in refrigerator for a 20-60 days. After danger of frost has passed and the cold treatment is over, directly sow wild Sunflower seeds into prepared seed beds that are weed free and the soil has been loosened. Broadcast the flower seeds and cover with 1/2 inch of soil. Sunflower Care: It is important not to over water the flowers. Too much water may result in soil loosening and losing stability to hold the large plants.

NOTE: Wild Sunflower seed has a higher percentage of hard seed. It is important to understand that there will be a delayed dormancy on a portion of the seed when planted.

Harvesting sunflower seeds

At harvest time, grasp the stem about six to eight inches below the flower head, and cut through the stem with a sharp knife or a pair of pruners. Allow to dry 2-4 days in a location safe from birds and squirrels

Growing sunflowers is easy, but knowing when to harvest the seeds requires a little bit of knowledge. If you harvest too soon, you will have plenty of seeds but small kernels inside. If you wait too long, however, they may dry out or simply eaten by birds.
Seeds are ready to harvest if:

  • Seeds are hard and developed
  • Flower petals begin to dry out and fall off
  • Back of the flower head turns yellowish-brown
  • You notice birds eating off the flower
