Coreopsis verticillata, commonly known as tickseed, is an easy-to-grow herbaceous perennial native to North America. In summer and autumn it produces bright yellow flowers that stand out against the finely dissected foliage.
Coreopsis verticillata 'Grandiflora' has larger flowers and grows to a greater height than the uncultivated species. The open flowers attract a range of pollinators including hoverflies and butterflies. It can be propagated by spring division or basal cuttings.
For best results, grow Coreopsis verticillata 'Grandiflora' in full sun or partial shade in well-drained soil, though it will perform better in full sun. This variety has gained the Royal Horticultural Society's prestigious Award of Garden Merit.
