Gaillardia plant named ‘Summers Kiss’

Abstract

A new cultivar of Gaillardia named ‘Summers Kiss’ that is distinguished by medium-green colored leaves, upright low-growing habit and large daisy-like flowers that are a melon color and that bloom in summer and fall. In combination these traits set ‘Summers Kiss’ apart from all other existing varieties of Gaillardia known to the inventor.

Description

Genus: Gaillardia.

Species: grandiflora.

Denomination: ‘Summers Kiss’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of blanket flower, an herbaceous perennial that is grown for use as an ornamental landscape and container plant. The new invention is known botanically as Gaillardia grandiflora and will be referred to hereinafter by the cultivar name ‘Summers Kiss’. Gaillardia is in the family Compositae, under which the commonly referred to “flower” is actually the inflorescence, and made up of smaller ray flowers and disc florets. The ray florets are what look like “petals”. For ease of clarification the common term “flower” is used herein to describe the inflorescence.

‘Summers Kiss’ is a chance seedling that was discovered by the inventor in 1997 in a cultivated area of Maryland. The inventor discovered the seedling in a large crop of seed grown Gaillardia ‘Goblin’ (not patented) that were on a propagation bench in the inventor's greenhouse. The female parent plant is presumed to be Gaillardia ‘Goblin’ and the male parent plant is presumed to be Gaillardia ‘Goblin’. ‘Summers Kiss’ differs from the parent plants in flower color.

‘Summers Kiss’ exhibits a low-growing, upright habit and large daisy-like flowers that open pink-orange in color and age to melon. The flower color has been characterized, by some, to be peach, apricot and sunset. Blooming occurs from mid summer into fall. Cultural requirements include full sun to light shade, moderate water and well-draining soil. Hardiness is classified as USDA Zone 5.

The distinguishing characteristic of ‘Summers Kiss’ is the flower color. The closest comparison plant is the presumed sport parent Gaillardia ‘Goblin’. ‘Summers Kiss’ is distinguishable from Gaillardia ‘Goblin’ by flower color. The petals of the flowers of Gaillardia ‘Goblin’ are red (close to Red Group 44A, The Royal Horticultural Colour Chart 2001 Edition) with yellow edges and tips. The petals of the flowers of ‘Summers Kiss’ are apricot colored (close to Orange Group 25D, The Royal Horticultural Colour Chart 2001 Edition). A second comparison cultivar of similar form and function to ‘Summers Kiss’ in Gaillardia ‘Golden Goblin’ whose flowers are pale lemon-yellow.

The first asexual reproduction of ‘Summers Kiss’ was carried out by the inventor in 1997 in a cultivated area of Maryland. The method used was softwood cuttings. Cuttings were placed in sandy soil, under light mist with bottom heat in the inventor's greenhouse. Since that time subsequent generations have been determined stable and true to type.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the distinguishing characteristics of the new Gaillardia cultivar. These traits in combination distinguish ‘Summers Kiss’ from all other existing varieties of Gaillardia known to the inventor. ‘Summers Kiss’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.

1. Gaillardia ‘Summers Kiss’ is an herbaceous perennial.

2. Gaillardia ‘Summers Kiss’ exhibits a low-growing upright habit.

3. Gaillardia ‘Summers Kiss’ exhibits large daisy-like flowers.

4. Gaillardia ‘Summers Kiss’ flowers open pink-orange color and age to a melon.

5. Gaillardia ‘Summers Kiss’ exhibits medium-green foliage.

6. Gaillardia ‘Summers Kiss’ is 46-62 cm. in height and 31-46 cm. in width at maturity when grown in the ground. After one season's growth in a 2 liter container, ‘Summers Kiss’ is approximately 39 cm in height and 30 cm in width.

7. Gaillardia ‘Summers Kiss’ is reproduced asexually.

8. Gaillardia ‘Summers Kiss’ is hardy to USDA Zone 5.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings illustrate the overall appearance of the new Gaillardia plant ‘Summers Kiss’ showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the drawings may differ from the color values cited in the detailed botanical description, which more accurately describes the actual colors of the new variety ‘Summers Kiss’. The drawings were made of plants that were grown in a greenhouse and planted in summer in a cultivated area of Maryland. The plants were 12-months old at the time and planted in the ground from 2-liter containers.

The drawing labeled as FIG. 1 illustrates the entire plant in bloom from a side perspective.

The drawing labeled as FIG. 2 illustrates a close-up view of the flower.

Drawings were made using conventional techniques and although flower and foliage colors may appear different from actual colors due to light reflectance, they are as accurate as possible by conventional photography.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of the new Gaillardia cultivar ‘Summers Kiss’. Observations, measurements, values and comparisons were compiled in Arroyo Grande Calif. from a 6-month-old plant in a 2-liter container that was greenhouse grown. Color determinations are made in accordance with The 2001 Royal Horticultural Society Colour Chart from London England, except where general color terms of ordinary dictionary significance are used. In the Compositae family, under which Gaillardia is classified, the commonly referred to “flower” is actually the inflorescence, and made up of smaller ray flowers and disc florets. For ease of clarification the common term “flower” is used here to designate a category of description. Under this category is the detailed botanical description of the parts of the inflorescence, which is commonly referred to as the “flower” of this plant.
