Coreopsis major

4 Photos


Summary

Coreopsis major looks very different from most other types of Coreopsis. Its leaves are held in what appear to be a whorl of 6 leaves around the stem; though there are actually two leaves, each with three leaflets, held opposite one another. This is an easy identifying characteristic. Greater tickseed blooms for much of the summer. However, the floral display in 2013 was much shorter than the other two years. This may have been influenced by poor plant health, as burnt leaf margins began to develop in mid-August of that year. Coreopsis major did not receive high ratings, despite its excellent disease resistance and long bloom period, because it lacked vigor. Over a period of three years, none of the plants increased in size.
