plant named ‘Red Sun’

Abstract

A new and distinct Gaillardia plant named ‘Red Sun’ characterized by a very compact habit, ray florets of dark red tipped with orange, overlapping ray florets in multiple layers, and excellent vigor.

Description

Botanical denomination: Gaillardia×grandiflora.

Variety designation: ‘Red Sun’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Gaillardia×grandiflora and given the cultivar name ‘Red Sun’. Gaillardia is in the family Asteraceae. This new cultivar is a third generation seeding originating from a planned breeding program to create new dwarf Gaillardia. The exact parents are unknown, unreleased, proprietary plants.

Compared to Gaillardia ‘Sunburst Burgundy’ (unpatented), the new cultivar is more compact and has orange tips on the red ray florets.

Compared to Gaillardia ‘Arizona Sun’ (unpatented), the new cultivar has darker flowers with orange only on the tips and more ray florets.

SUMMARY OF THE INVENTION

This new Gaillardia cultivar is distinguished by:

• • 1. a very compact habit,
  • 2. ray florets of dark red tipped with orange,
  • 3. overlapping ray florets in multiple layers, and
  • 4. excellent vigor.

This new cultivar has been reproduced only by asexual propagation (division and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by division 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 DRAWING

FIG. 1 shows Gaillardia ‘Red Sun’ in full bloom as a 6 month old in the field in full sun in early August in Canby, Oreg.
