Coreopsis 2018 Year ofIn the context of the campaign ‘2018 Year of the Coreopsis’ the National Garden Bureau (NGB) in the US has posted a fact sheet and background story written by Darwin Perennials’ Karl Batschke. The NGB encourages growers, marketers and retailers to take advantage of printable/shareble materials for its ‘Year of…’ plants.
Batschke notes that as many as 80 Coreopsis species can be found naturalized in the Americas with 38 listed in the lower forty-eight states. “Coreopsis can be hardy to USDA zone 3 (Coreopsis verticillata, Coreopsis tripteris) and range into the extreme heat of Florida and the Southwestern states (Coreopsis floridana, Coreopsis tinctoria). Many of the species are self-seeding and considered annuals (Coreopsis tinctoria) however the most common perennial Coreopsis include Whorled tickseed (Coreopsis verticillata), Lobed tickseed (Coreopsis auriculata) and Large Flowered tickseed (Coreopsis grandiflora).”
“Coreopsis grandiflora ‘Early Sunrise’ was designated an All-American Selections Winner in 1989 and this variety remains among the best-selling Coreopsis for garden use’, Batschke wrote in the NGB post. Other important varieties include Coreopsis verticillata ‘Moonbeam,’ Coreopsis verticillata ‘Zagreb’ and Coreopsis auriculata ‘Nana’. “Coreopsis species have been heavily hybridized for decades to improve plant flowering, flower size, and disease tolerance.

Coreopsis grandiflora ‘Sunkiss’ and the Big Bang, Hardy Jewel and UpTick series [pictured above] are among the most significant new introductions and represent dedication and years of effort by plant breeders”, states Batschke. “There are dozens of commercially available cultivars varying in height from 6” to 3’ and covering a broad color range from the traditional yellow to caramel, bronze, red, gold, rose and cream-white. They can be incorporated into nearly any area of the garden where the height and color are needed.”
The NGB illustrated the post with the images of nearly fifty Coreopsis varieties from breeders as Star Roses and Plants, Darwin Perennnials, Dümmen Orange, Kieft Seed, Harris Seeds, Hem Genetics, Danziger, Syngenta, Jung Seed and Terra Nova Nurseries.
