ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Coreopsis
plant, botanically known as
Coreopsis rosea×Coreopsis verticillata
and hereinafter referred to by the name ‘Limerock Ruby’.
The new
Coreopsis
was discovered by the Inventor in a controlled environment in Lincoln, R.I. on Aug. 3, 1998, as a chance seedling from random cross-pollinations of unidentified selections of
Coreopsis rosea
and
Coreopsis verticillata
, not patented. The new
Coreopsis
was observed as a single plant in a group of flowering plants of the unidentified selections of
Coreopsis rosea
and
Coreopsis verticillata
. The selection of this plant was based on its unique ray and disc floret coloration.
Asexual reproduction of the new
Coreopsis
by divisions taken in a controlled environment in Lincoln, R.I. since Aug. 3, 1998, has shown that the unique features of this new
Coreopsis
are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Limerock Ruby has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Limerock Ruby’. These characteristics in combination distinguish ‘Limerock Ruby’ as a new and distinct cultivar:
1. Daisy-type inflorescences that are about 3.25 cm in diameter.
2. Unique dark crimson red-colored ray florets and dark purple-colored disc florets.
3. Very freely flowering with numerous inflorescences per plant.
4. Upright and outwardly spreading growth habit.
Plants of the new
Coreopsis
differ from plants of the parent selections and other known cultivars of
Coreopsis rosea
and
Coreopsis verticillata
primarily in ray and disc floret coloration. Plants of selections and cultivars of
Coreopsis rosea
known to the Inventor, not patented, have yellow-colored ray and disc florets and plants of selections and cultivars of
Coreopsis verticillata
known to the Inventor, not patented, have pink-colored ray florets and yellow-colored disc florets.
