ABSTRACT:

Botanical classification:
Spirea japonica.
Variety denomination: ‘White Gold’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Spirea, a deciduous ornamental. The new cultivar is known botanically as
Spirea japonica
and will be referred to hereinafter by the cultivar name ‘White Gold’.
The breeding for a Spirea with gold leaves and white flowers began in 1993 in Hampshire, England when the inventor crossed the female parent
Spirea japonica
var.
albiflora
with the male parent
Spirea japonica
‘Candlelight’ (unpatented). The resultant seedlings flowered in 1994 and because none of the yellow-leaved seedlings exhibited white flowers, a yellow seedling was selected and used as the female parent and crossed with the male parent
Spirea japonica
var.
albiflora
. As a result of this cross several seedlings were produced which had gold leaves and white flowers. When these seedlings were developed and flowering freely, a final selection was made. ‘White Gold’ was selected by the inventor in 1996.
The distinguishing characteristics of ‘White gold’ are hardiness, compact habit, diminutive cream-white flowers and golden yellow-green foliage. ‘White Gold’ is distinguishable from all other cultivars of
Spirea japonica
by its cream-white flowers. The inventor has no knowledge of any other cultivars of
Spirea japonica
which combine golden foliage with cream-white flowers. All other golden-foliaged cultivars of
Spirea japonica
known to the inventor exhibit pink or mauve colored flowers.
‘White Gold’ was first asexually propagated by the inventor in Hampshire, United Kingdom in 1996 using softwood cuttings. Since that time, under careful observation, the distinguishing characteristics have been determined stable and uniform in successive generations.
SUMMARY OF THE INVENTION
The following represent the distinguishing characteristics of the new Spirea cultivar ‘White Gold’. In combination these traits set ‘White Gold’ apart from all other existing varieties of Spirea known to the inventor. ‘White Gold’ 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. Spirea ‘White Gold’ exhibits dense clusters of cream-white flowers in summer.
2. Spirea ‘White Gold’ is 75 cm. in height and 75 cm. in width.
3. Spirea ‘White Gold’ exhibits golden yellow-green foliage.
4. Spirea ‘White Gold’ is winter hardy.
5. Spirea ‘White Gold’ exhibits a compact habit.
