Botanical designation: Coreopsis verticillata.

Cultivar denomination: ‘Curry Up’.


The present invention relates to the new and distinct threadleaf coreopsis herein also referred to as Coreopsis ‘Curry Up’, by the cultivar name, ‘Curry Up’, or as the new plant. The new plant was selected by the inventor in June of 2012 from an isolated block of plants all derived from the seedling with breeder code HK10-06-01 (not patented) which is a seedling of Coreopsis ‘Route 66’ U.S. Plant Pat. No. 20,609 collected in the summer of 2011 from a proprietary unreleased seedling identified with the in the fields of a wholesale perennial grower based in Zeeland, Mich., USA. It was then isolated and compared in subsequent years to other coreopsis and subsequently found to be different from all cultivars known to the discoverer.

Asexual propagation at the same nursery in Zeeland, Mich., USA by cuttings has shown ‘Curry Up’ to be stable and reproduce true to type in successive generations.

No plants of Coreopsis ‘Curry Up’ have been sold, in this country or anywhere in the world, prior to the filing of this application, nor has any disclosure of the new plant been made prior to the filing of this application with the exception of that which may have been disclosed within one year of the filing date of this application and was either derived directly or indirectly from the inventor.


Coreopsis ‘Curry Up’ has not been observed in all possible environmental conditions. The phenotype may vary slightly with changes in environments such as light intensity, fertility, water availability, etc. without, however any variation in genotype.

Coreopsis ‘Curry Up’ is distinct from all cultivars known to the inventor in the following traits:

    • 1. Narrow foliage with compact height and dense habit.
    • 2. Heavy flowering with ray petals of clear golden yellow with dark red eyes.
    • 3. Flowers produced tightly and densely above the bright-green thin foliage.
    • 4. Long flowering period beginning with concentration in mid-June and continuing until late summer.

Plants of Coreopsis ‘Curry Up’ are most similar to ‘Firefly’ U.S. Plant Pat. No. 26,295, ‘Bengal Tiger’ U.S. Plant Pat. No. 25,345, ‘Sunset Strip’ U.S. Plant Pat. No. 22,670 and ‘Red Shift’ U.S. Plant Pat. No. 20,412. ‘Red Shift’ produces ray flower petals that have a narrower red eye with more purple coloration at the base and distal portion is lighter yellow than the more golden yellow and larger burgundy eye of ‘Curry Up’. The ray petals of ‘Sunset Strip’ are more orange on the distal portion and more reddish orange in the eye than the new plant. The distal portion of the ray petals of ‘Bengal Tiger’ is a lighter yellow than that of ‘Curry Up’, and the eye of the former is wider or larger than the new plant. The habit of ‘Bengal Tiger’ is also shorter and wider than that of ‘Curry Up’. ‘Firefly’ is much shorter and narrower than ‘Curry Up’ in habit. No plants of the female parent were saved, so no mature plant comparison could be made.


The color drawings illustrate the overall characteristics of Coreopsis ‘Curry Up’ as a three-year-old plant. The colors are as true as reasonably possible given the technology available. The color values may vary slightly depending on light intensity and quality.

The following description is based on a three-year-old plant growing in a full-sun trial garden in Zeeland, Mich., USA. Environmental conditions for the growing season daytime temperatures range between 12-30° C., and night temperatures range between 6-19° C.
