Coreopsis tinctoria is a lovely wildflower, and a wonderful dye plant.
The seeds in this listing were collected from the plants in my garden. The colors of the flowers include lemon yellow, pure sunshine yellow, mahogany red and flowers with a combination of red and yellow.
When the flowers are used for natural dyeing, the resulting colors range from pale to rich golden yellow. Over-dyeing with indigo produces gorgeous greens. Over-dyeing with madder yields lovely pinks and oranges.

It is quite easy to grow in average soil with plenty of sunshine.
Keep the small seedlings moist until the plants are well established.
This listing is for 100+ seeds.
I add plenty of extra seeds to each packet, just in case...:)

These seeds are often best started indoors a few weeks before the final date of frost in your area.
This method is especially helpful for gardeners in areas with shorter growing seasons.
Usually these Coreopsis tinctoria seeds will sprout in about 10 to 14 days, depending on the temperature, and amount of moisture in the soil.
Seeds are very small and need light to sprout.
They germinate more readily when not covered with soil.
Pressing the seeds firmly onto the soil surface and maintaining moisture is the best method I've found for good germination.

I prefer to start them in containers so that I have more control over the temperature and moisture requirements.
Using a spray bottle is a good way to keep the soil moist without dislodging the little seeds.

When they're planted directly outdoors they may face a few natural dangers. The seeds may be washed about by heavy rain, dried out quickly by sun and wind, and they seem to be a favorite snack for hungry finches and sparrows...:)

When all danger of frost has passed, plant the coreopsis seedlings outdoors in a spot where they'll receive many hours of sunshine each day and give them plenty of water.
