USPP28570P2 - Coreopsis plant named ‘Madras Magic’ - Google Patents

Abstract

A new and distinct Coreopsis plant named ‘Madras Magic’ characterized by daisy-type inflorescences that grow to 4 cm in diameter, inflorescences that are dark rose burgundy with streaks of creamy white near the tips, hardy to Zone 6, maybe lower, grass green foliage on short stems, flowering for the whole summer, a low, mounding habit, and excellent vigor.

Description

Latin name: Coreopsis verticillata hybrid.

Varietal denomination: ‘Madras Magic’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Coreopsis and given the cultivar name ‘Madras Magic’. Coreopsis is in the family Asteraceae. This new cultivar originated from a controlled breeding program to produce hardy compact Coreopsis. The new cultivar originated from planned cross of two proprietary unnamed Coreopsis verticillata hybrid seedlings. The new cultivar of Coreopsis is an herbaceous perennial to be grown for landscape and container use in a sunny site.

Compared to the parent seedlings the new variety is much shorter with larger flowers and a more upright habit.

Compared to Coreopsis ‘Show Stopper’, U.S. Plant Pat. No. 22,671, the new cultivar is much shorter and much more compact.

Compared to Coreopsis ‘Cosmic Evolution’, U.S. Plant Pat. No. 22,9453, the new cultivar is smaller and more compact and has smaller, darker flowers.

Compared to Coreopsis ‘Mercury Rising’, U.S. Plant Pat. No. 24,689, the new cultivar has a tighter more compact habit and flowers that are a dark rose burgundy rather than red.

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 ‘Madras Magic’ as a new and distinct cultivar:

• • 1. daisy-type inflorescences that grow to 4 cm in diameter,
  • 2. inflorescences that are dark rose burgundy with streaks of creamy white near the tips,
  • 3. hardy to Lone 6, maybe lower,
  • 4. grass green foliage on short stems,
  • 5. flowering for the whole summer,
  • 6. a low, mounding habit, and
  • 7. 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.
