Abstract: A new cultivar of hybrid Coreopsis named `Sienna Sunset` characterized it's large, abundant apricot colored inflorescences, its long blooming habit, its vigorous growth habit, its densely branched plant habit, its relative resistance to powdery mildew and hardiness at least to U.S.D.A. Zones 5 to 9.
Claim: It is claimed:

1. A new and distinct cultivar of Coreopsis plant named `Sienna Sunset` as herein illustrated and described.
Description: Botanicalclassification: Coreopsis hybrid.

Variety denomination: `Sienna Sunset`.


The present invention relates to a new and distinct cultivar of Coreopsis plant, botanically known as Coreopsis verticillata `Sienna Sunset` and will be referred to hereinafter by its cultivar name, `Sienna Sunset`. The new cultivar ofthreadleaf type Coreopsis is grown an herbaceous perennial grown for landscape and container use.

The new invention arose as a naturally occurring branch mutation of Coreopsis `Creme Brulee` (U.S. Plant Pat. No. 16,096) in a container growing outdoors in the Inventor's nursery in Kensington, Conn. in September of 2007.

Asexual reproduction of the new cultivar was first accomplished by stem cuttings by the Inventor in Kensington, Conn. in November of 2007. The characteristics of this cultivar have been determined to be stable and are reproduced true to type insuccessive generations.


The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar. These attributes in combination distinguish `Sienna Sunset` as unique from all Coreopsis cultivars and species known to theinventor. 1. `Sienna Sunset` exhibits composite inflorescences that are apricot in color (a blend of yellow and orange). 2. `Sienna Sunset` exhibits abundant, large sized flowers that are held near the top of the canopy. 3. `Sienna Sunset` is longblooming and blooms from June until frost in Connecticut. 4. `Sienna Sunset` is densely branched. 5. `Sienna Sunset` exhibits a vigorous growth habit. 6. `Sienna Sunset` is hardy at least in U.S.D.A. Zones 5 to 9. 7. `Sienna Sunset` exhibits isrelatively resistance to powdery mildew.

`Sienna Sunset` is similar to its parent plant, `Creme Brulee`, in flower number and size, disease resistance and blooming period, however `Creme Brulee` exhibits inflorescences that are yellow in color. `Sienna Sunset` can also be compared to`Moonbeam` (not patented). `Sienna Sunset` differs from `Moonbeam` in having larger inflorescences that are apricot in color rather than yellow, brighter green foliage, better resistance to powdery mildew, blooms held new the top of the plant canopyrather than above the foliage, and a more vigorous growth habit.


The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Coreopsis. The photographs were taken of a nine-month old plant of `Sienna Sunset` as grown outdoors in a garden in New Hope, Minn.

The photograph in FIG. 1 is a side view of `Sienna Sunset` and provides a view of its plant habit and blooming habit.

The photograph in FIG. 2 provides a close-up view of the inflorescences of `Sienna Sunset`.

The Colors in the photograph may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Coreopsis.


The following is a detailed description of a nine month-old plant the new cultivar as grown outdoors in a garden bed in New Hope, Minn. The phenotype of the new cultivar may vary with variations in environmental, climatic, and culturalconditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with the 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms ofordinary dictionary significance are used.
