The Coreopsis grandiflora is a perennial herbaceous plant of the Asteraceae family, like daisies and dandelions. Native to North America, it grows in meadows and forest edges from California to Mexico. Its remarkable cold resistance, tolerating temperatures as low as -18°C (1°F), makes it a robust plant. Although perennial, it is not uncommon to cultivate it as an annual. Its uninterrupted flowering quickly exhausts the plant, which has a lifespan of only 2 or 3 years; however, it easily self-seeds. The term "coreopsis" originates from the Greek words korè, which means young girl, and opsis, which means eye, referring to the remarkable beauty of this flower, hence its name in some languages of 'Young Girl's Eye'.
