Coreopsis

Stratify seed by placing in a damp paper towel, in a plastic bag in the fridge for 30-60 days to ensure uniform germination. After stratification period, remove seed from fridge and sow indoors in pots 4-6 weeks before last frost date or outdoors directly in the soil. Alternatively, sow seed outdoors in the fall and allow to stratify naturally. Sow seed .5 cm deep and firm soil.
