Claims
I claim:
1. A new and distinct Coreopsis plant as herein illustrated and
described.
Description
Botanical denomination: Coreopsis hybrid.
Variety designation: `Gold Nugget`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct hybrid of
Coreopsis and given the cultivar name `Gold Nugget`. Coreopsis is
in the family Asteraceae. This new cultivar originated from a
branch sport from Coreopsis `Snowberry`(U.S. Plant Pat. No. 18/560)
grown in a controlled greenhouse environment.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are
determined to be the unique characteristics of the new variety.
These characteristics in combination distinguish Coreopsis `Gold
Nugget` as a new and distinct cultivar: 1. Large, daisy-type
flowers that grow to 4.5 cm in diameter; 2. Unique, bright yellow
and maroon bi-colored ray florets; 3. Grass green foliage; 4. Very
free branching; 5. Very free flowering; 6. Long bloom time; 7.
Mounding habit.
This new cultivar has been reproduced only by asexual propagation
(cuttings and tissue culture). Each of the progeny exhibits
identical characteristics to the original plant. Asexual
propagation by cuttings and tissue culture using standard
micropropagation techniques with terminal and lateral shoots, as
done in Canby, Oreg., shows that the foregoing characteristics and
distinctions come true to form and are established and transmitted
through succeeding propagations. The present invention has not been
evaluated under all possible environmental conditions. The
phenotype may vary with variations in environment without a change
in the genotype of the plant.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The photograph shows a nine-month-old Coreopsis `Gold Nugget`
growing in the ground in the trial field in August 2007, in Canby,
Oreg.

COMPARISONS TO SIMILAR COREOPSIS
Compared to Coreopsis `Snowberry` (U.S. Plant Pat. No. 18,560), the
mother plant, the new variety has bright yellow rather than creamy
white ray florets. Both flowers have a distinctive maroon eye.
Compared to Coreopsis `Autumn Blush` (U.S. Plant Pat. No. 18,184),
the new variety has a much darker yellow ray floret color.
