Coneflowers are also known as black-eyed Susans and rudbeckia. They produce yellow or white flowers and germinating them in the garden is a straightforward task.
Starting Indoors
-
Starting coneflower seeds indoors allows them to get a more sure start when they are at their most fragile. Place them in a plastic bag filled with soil and then place them in the refrigerator for two weeks. After this, sow them in an indoor container about six weeks after the last frost.
Time Frame
-
Plant Biology states that coneflowers should germinate within one to three weeks. Once they have started to sprout, plant them outdoors at any point after the last frost.
Conditions
-
Place the germinated coneflowers in an outdoor location that has neutral or slightly acidic soil that drains well. Choose a location that is sunny or slightly shaded. Sow the seeds on the surface of the soil and cover them very lightly.
