Tall Coneflower / Rudbeckia laciniata
Also called Cutleaf Coneflower, this beautiful summer blooming wildflower ranges from 4 to 8 feet and can even grow in part shade and shade. In its preferred rich, moist soil conditions, it can be rhizomatous and spread, so you may want to be cautious with it in smaller spaces. It also has lovely foliage. The seeds are eaten by native birds and its base leaves are edible in spring.
Its geographic range extends from Maine in the northeast, to Arizona and Montana in the west, and down to Florida in the southeast.

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.
