showy fluted yellow petals and dark green foliage
Coreopsis hybrid Jethro Tull
Family : Asteraceae
Few perennials produce more flower than a Coreopsis. Their long flowering period with an attractive range of colours make them deservedly popular. The Limerock series should be treated as a 1 year container or bedding plant as they are not reliably winter hardy but few plants can match their flower power.
