USPP21069P2 - Coreopsis plant named ‘Pink Lady’ - Google Patents

Abstract

A new and distinct Coreopsis plant named ‘Pink Lady’ characterized by medium sized, clear pink, daisy like flowers, very free flowering, a mounding habit, and excellent vigor.

Description

Botanical name: Coreopsis sp.

Variety designation: ‘Pink Lady’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct plant of Coreopsis and given the cultivar name ‘Pink Lady’. Coreopsis is in the family Asteraceae. This new cultivar originated as a seedling found in the nursery from unknown propriety plants in Canby, Oreg. and reproduced in tissue culture where further selections were made. This selection was made for its clear pink flowers.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Pink Lady’. These characteristics in combination distinguish ‘Pink Lady’ as a new and distinct cultivar:

• • 1. medium sized, clear pink, daisy like flowers,
  • 2. mounding habit,
  • 3. very free flowering
  • 4. and excellent vigor.

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.
