Coreopsis plant named ‘RP #5’

Abstract

A new and distinct Coreopsis plant named ‘RP #5’ characterized by very free flowering rust orange colored, daisy-like flowers, a low mounding habit, and excellent vigor.

Description

Botanical designation: Coreopsis hybrid (of unknown origin).

Variety denomination: ‘RP #5’.

CROSS REFERENCE TO RELATED APPLICATIONS

The present application is related to U.S. Plant patent application Ser. No. 11/488,815, directed to a Coreopsis plant named ‘Rum Punch’; U.S. Plant patent application Ser. No. 11/592,654, directed to a Coreopsis plant named ‘RP #1’; and to U.S. Plant patent application Ser. No. 11/592,083, directed to a Coreopsis plant named ‘RP#4’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct plant of Coreopsis and given the cultivar name ‘RP #5’. Coreopsis is in the family Asteraceae. This new cultivar originated as a tissue culture mutation from Coreopsis ‘Rum Punch’ (U.S. Plant patent application Ser. No. 11/488,815). ‘RP #5’ was one of several interesting mutations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘RP #5’. These characteristics in combination distinguish ‘RP #5’ as a new and distinct cultivar:

• • 1. Unique rust orange colored daisy-like flowers.
  • 2. Low, mounding habit.
  • 3. Very free flowering.
  • 4. 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.
