Clarkia Flower Seeds grow wild in most of the USA. Clarkia flowers are very hardy and low maintenance. There will be multiple blooms on each stem as well as different colors: whites, pinks, and purples. These will grow three or four feet tall. Because they grow as an annual, they will reseed themselves. Clarkia flowers are very unique looking flowers that grow from seeds. Buy these Heirloom flower seeds online today! Happy growing!!!
