Coreopsis

Tickseeds provide masses of aster-like flowers, normally yellow, but also pink, cream, red, or a mix. Over a long period from summer into autumn and lasting well when cut. Foliage typically narrow, opposite and neat. Plenty of cultivated forms available, which make a reliable long-lived splash of colour in the middle to near the front of a sunny border. From the Greek, koris, meaning 'bug', the common name tickseed, all alluding to the seeds resemblance to ticks!
