ABSTRACT:
Botanical Classifciation:
Clematis diversifolia.
Variety denomination: ‘Zoin’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Clematis, a woody half climber that is grown for use in small gardens and for its cut flowers. The new cultivar is known botanically as a
Clematis diversifolia
and will be referred to hereinafter by the cultivar name ‘Zoin’.
‘Zoin’ was bred by the inventor in 1993 in a cultivated area of Boskoop, Netherlands by crossing the female parent
Clematis integrifolia
‘Rosea’ (not patented) with the male parent Clematis ‘Warsawska Nike’ (not patented). The breeder's goal was to produce a pink form of Clematis ‘Durandii’. In addition, the breeder sought to produce a low-growing clematis resistant to disease and wilt that produces long lasting cut flowers. Only one cross was made. There were no intermediate crosses. ‘Zoin’ was selected by the inventor in 1997 from the many resulting seedlings. Its pink flower with contrasting yellow stamens is a unique to the diversifolia group.
The distinguishing characteristics of ‘Zoin’ are its upright habit, pink bell shaped flowers, long flowering, low to medium height and blossoms that are suitable for use as cut flowers. The closest comparison plant is
Clematis durandii
(unpatented) which exhibits a blue flower. ‘Zoin’ is distinguishable from
Clematis durandii
by its pink colored flowers.
‘Zoin’ was first asexually propagated by the inventor in Boskoop, Netherlands in 1998 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 Clematis cultivar ‘Zoin’. In combination these traits set ‘Zoin’ apart from all other existing varieties of Clematis known to the inventor. ‘Zoin’ 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. The flowers of Clematis ‘Zoin’ are suitable for use as cut flowers.
2. Clematis ‘Zoin’ is low to medium in height and suitable for a small garden.
3. Clematis ‘Zoin’ exhibits bell shaped pink flowers in spring and summer.
4. Clematis ‘Zoin’ is a woody half climber that is hardy to USDA Zone 5.
5. Clematis ‘Zoin’ exhibits dark green foliage.
6. Clematis ‘Zoin’ is resistant to wilt and disease.
7. Clematis ‘Zoin’ exhibits an upright habit.
