Coreopsis grandiflora is a North American species of perennial plant in the family Asteraceae. The common name is large-flowered tickseed.[4] It is found in eastern Canada (Quebec, Ontario, New Brunswick) and much of the United States, especially the south-central part of the country (Oklahoma, Arkansas, etc.).[5] The species is widely cultivated in China and naturalized there.[6]
Coreopsis grandiflora is a perennial herb[7] sometimes greater than 60 cm (2 feet) tall. It produces yellow ray and disc flowers.[8] Its native habitats include prairies, glades, open woods, thickets, roadsides and open ground. The Latin specific epithet grandiflora means large-flowered.[9] The plant attracts bees and butterflies.[10]
In the UK the cultivar 'Early Sunrise'[11] has received the Royal Horticultural Society's Award of Garden Merit.
