Abstract

A new and distinct cultivar of Caryopteris named ‘GOLD GIANT’ that is characterized by strong upright habit, mid-deep blue flowers, and bright golden yellow foliage throughout the season. In combination these traits set ‘GOLD GIANT’ apart from all other existing varieties of Caryopteris known to the inventor.

Description

Genus: Caryopteris.
Species: ×clandonensis.
Denomination: ‘GOLD GIANT’.
BACKGROUND OF THE INVENTION
This application claims the benefit of priority under 35 U.S.C. 119(e) of U.S. Provisional Application No. 61/269,884 filed on Jul. 1, 2009, entitled Caryopteris Plant Named ‘GOLD GIANT’.
The present invention relates to a new and distinct cultivar of Caryopteris, also known as blue-mist or bluebeard, which is grown as an ornamental shrub for use in the garden and landscape. The new invention from the family Verbenaceae is known botanically as Caryopteris×clandonensis and will be referred to hereinafter by the cultivar name ‘GOLD GIANT’.
‘GOLD GIANT’ resulted from a long term breeding program within the genus Caryopteris which the inventor commenced in 1990 and carried out at the inventor's nursery in Hampshire, United Kingdom. ‘GOLD GIANT’ is a seedling selection derived from the deliberate open cross-pollination of the seed parent, an individual Caryopteris clandonensis ‘Worcester Gold’ (unpatented) and the pollen parent, an individual Caryopteris clandonensis ‘Worcester Gold’ (unpatented).
To initiate the breeding process the inventor isolated container-grown plants of Caryopteris ‘Worcester Gold’ on a nursery bench which was isolated from all other Caryopteris in the nursery. Following successful cross-pollination the resulting seed was collected by the inventor and sown in the autumn of 2000, with the intention of producing new seedlings with desired traits. The inventor selected ‘GOLD GIANT’ in 2004 based on the criteria of vigor, habit, and foliage color.
The distinguishing traits of ‘GOLD GIANT’ are strong upright habit, profusions of mid-deep blue flowers from early summer through fall, and bright golden yellow foliage throughout the season, with dark contrasting stems. ‘GOLD GIANT’ is vigorous, growing to 60 cm. in height and 76 cm. in width during the first year, reaching 90 cm-110 cm. in height and 90 cm-110 cm. in width at maturity. Cultural requirements include full sun, well-draining soil and minimal to moderate water. ‘GOLD GIANT’ is hardy to USDA Zone 6. Once established, ‘GOLD GIANT’ is drought tolerant and heat tolerant.
The closest comparison plant known to the inventor is Caryopteris ‘Worcester Gold’. The comparison plant exhibits pale summer foliage, wispy open habit, and narrow leaves. The new Caryopteris variety ‘GOLD GIANT’ is distinguishable from the comparison plant by strong upright habit, broad leaves, and bright golden yellow foliage that remains so throughout the season without fading.
‘GOLD GIANT’ was first asexually reproduced by the inventor in Greatham, Hampshire, United Kingdom, in 2005. Asexual propagation was accomplished using semi-ripe stem cuttings. Since that time under careful observation, the distinguishing characteristics of ‘GOLD GIANT’ have been determined stable and uniform, and to reproduce true to type in successive generations of asexual propagation.
SUMMARY OF THE INVENTION
The distinguishing characteristics of the new Caryopteris cultivar named ‘GOLD GIANT’ are as follows. In combination these traits set ‘GOLD GIANT’ apart from all other existing varieties of Caryopteris known to the inventor. ‘GOLD GIANT’ has not been tested under all possible conditions, and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions without however any variance in genotype.
    • 1. ‘GOLD GIANT’ exhibits strong upright habit.
    • 2. The stems of ‘GOLD GIANT’ are dark brown to black in color.
    • 3. The foliage of ‘GOLD GIANT’ is bright golden yellow.
    • 4. The golden yellow color of the foliage of ‘GOLD GIANT’ persists through the summer and into fall without fading.
    • 5. The leaves of ‘GOLD GIANT’ are irregularly toothed.
    • 6. The flowers of ‘GOLD GIANT’ are mid-deep blue in color.
    • 7. At maturity, a plant of ‘GOLD GIANT’ achieves a height in the range of 90 cm -110 cm. and a spread in the range of 90 cm-110 cm.
    • 8. ‘GOLD GIANT’ is hardy to USDA Zone 6.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying color drawings illustrate the overall appearance of the new Caryopteris cultivar named ‘GOLD GIANT’ showing the color of its foliage and flowers as true as is reasonably possible to obtain in color reproductions of this type.
Color in the drawings may differ from color values cited in the detailed botanical description, which accurately describe the actual color of the new variety ‘GOLD GIANT’.
The drawing labeled as FIG. 1 depicts an overhead view of a one-year-old plant of ‘GOLD GIANT’ growing in a 1-liter container out-of-doors in Hampshire, United Kingdom.
The drawing labeled as FIG. 2 depicts a close-up view of the flower buds and flowers of a planting of ‘GOLD GIANT’ in the ground in Hampshire, United Kingdom.
Drawings were made using conventional techniques and although flower and foliage color may appear different from actual color 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 Caryopteris cultivar named ‘GOLD GIANT’. Observations, measurements, values and comparisons were collected in April from a 6-month-old 1-liter container plant growing out-of-doors in Arroyo Grande, Calif. 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. The growing requirements of the new variety ‘GOLD GIANT’ are similar to the species.
