Sunflower / Helianthus annuus
Loved by humans and bees and butterflies. This is a mixed seed pack of different breeds, which will vary from year to year depending on the harvest. Annual sunflowers always put on an impressive display, blooming from summer through fall. With adequate light and soil nutrition, the varieties we grow will tend to have multiple flowers. We do not generally grow Mammoth Grey Stripe sunflowers because they tend to have only one flower, which while they do grow large, they do not tend to last long. Our view is that it is more helpful to have several or more flowers that bloom over period of weeks for the benefits to pollinators and the ecosystem.
Seed Planting/Germination Key
Storage: Store in a cool, dry, dark place prior to planting.
Rule of thumb for depth of planting: The maximum depth should generally be half the width of the seed, but many wildflower seeds will germinate well if sown on the surface.
Easy: Generally germinates within 5 to 30 days with no need for cold pretreatment. Keep potting mix or soil consistently moist during the germination period.
Cold(30): Germination rates are higher if cold pretreatment applied either by placing the seed within moist paper towel or sand within a refrigerator for 30 days or outside in late winter.
Cold(60): Germination rates are higher if cold pretreatment applied either by placing the seed within moist paper towel or sand within a refrigerator for 60 days or outside in mid-winter.
Cold(90); Outdoors: Germination rates are higher if cold pretreatment applied either by placing the seed within moist paper towel or sand within a refrigerator for 90 days or outside in late fall or early winter. The best route is to plant these outdoors in either a pot or directly on the soil.
