How to Germinate Perennial Coreopsis

Perennial coreopsis plants grow best in United States Department of Agriculture zones five through 10. The coreopsis flowers, also known as tickseed, have a long blooming season that lasts from April to September. The flowers are golden yellow or pale white. The plants are propagated by either dividing the root crowns or germinating the seeds. The seeds usually are germinated outdoors directly in the flowerbed and begin to grow within two to three weeks.
