ABSTRACT:
LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED
Euonymus japonicus.
VARIETY DENOMINATION
Heespierrolino; c.v. Pierrolino.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Euonymus plant, hereinafter referred to by the cultivar name ‘Heespierrolino’. ‘Heespierrolino’ is a spontaneous mutant of an unnamed
Euonymus japonicus
cultivar selected by or under the supervision of the inventor, Adrianus L. P. van Heesbeen, in a cultivated environment in Haarsteeg, The Netherlands.
Asexual reproduction of the new cultivar by stem cutting was first performed at the end of 1997 in Haarsteeg, The Netherlands and has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction.
BRIEF DESCRIPTION OF THE INVENTION
The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Heespierrolino’ which in combination distinguish this
Euonymus japonicus
as a new and distinct cultivar:
1. White coloration of young leaves and young sprigs;
2. Broad and erect growth habit; and
3. White sprig production year round when pinched.
‘Heespierrolino’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary significantly with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the plant. The following observations, measurements and values describe the new cultivar as grown in Haarsteeg, The Netherlands, under conditions which closely approximate those generally used in commercial practice.
Of the many commercial cultivars known to the present inventor, the most similar in comparison to ‘Hees01’ is cultivar
Euonymus fortunei
‘Harlequin’. ‘Heespierrolino’ produces young sprigs almost year round. ‘Harlequin’ produces white sprigs only in April, May, June, and July. ‘Heespierrolino’ grows more erect and less broad than ‘Harlequin’ while the rate of growth of ‘Harlequin’ is slightly slower. The young leaves of ‘Heespierrolino’ are whiter and much less speckled than the young leaves of ‘Harlequin’.
‘Heespierrolino’ produces more, though shorter branches than ‘Harlequin’. The branches of ‘Heespierrolino’ stay white for a long time, sometimes up to the roots with small green stripes along the length stripes in the middle to the bottom. The branches of ‘Harlequin’ are green with green/white stripes are more green/white than white although vertically they still have green stripes.
The leaf shape of ‘Heespierrolino’ is obovate to elliptic whereas ‘Harlequin’ has ovate shaped leaves. Leaf base of ‘Heespierrolino’ is acute, the leaf base of ‘Harlequin’ is obtuse. The leaf length of ‘Heespierrolino’ is up to 5 cm, and width up to 2.5 cm, while the leaf length of ‘Harlequin’ is up to 3 cm and width up to 2 cm. The petiole length of ‘Heespierrolino’ at 5-7 mm is longer than the petiole length of ‘Harlequin’ at 3-5 mm.
