Lance-Leaf Coreopsis / Coreopsis lanceolata
A well-behaved garden plant beloved by native bees and butterflies. Beginning in May, it's one of the first wildflower plants to bloom after the spring ephemeral season passes and a true herald of the more boisterous summer blooming season to come. If you dead-head them, they will continue to produce blooms for weeks.
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.
