USPP24847P3 - Coreopsis plant named ‘Desert Coral’ - Google Patents

Abstract

A new and distinct Coreopsis plant named ‘Desert Coral’ characterized by large daisy-type flowers that grow to 3.5 cm in diameter, pink orange flowers with a dark red eye, grass green foliage on strong, upright, short stems, flowering for the whole summer, and a upright, mounding habit.

Description

Botanical denomination: Coreopsis hybrid.

Variety designation: ‘Desert Coral’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Coreopsis and given the cultivar name ‘Desert Coral’. Coreopsis is in the family Asteraceae. This new cultivar originated from an open pollinated cross using proprietary unprotected plants in the field. Seedlings were evaluated for new flower colors in large flowered, compact, free flowering habits. The new cultivar was selected for its new flower color.

Compared to Coreopsis ‘Pumpkin Pie’ (U.S. Plant Pat. No. 22,519), the new cultivar has flowers that are pink orange with a red eye rather than deep orange with a red eye. The new cultivar is taller.

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 ‘Desert Coral’ as a new and distinct cultivar:

• • 1. large daisy-type flowers that grow to 3.5 cm in diameter,
  • 2. pink orange flowers with a dark red eye,
  • 3. grass green foliage on strong, upright, short stems,
  • 4. flowering for the whole summer, and
  • 5. an upright, 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
