ABSTRACT:
CLASSIFICATION
Botanical:
Rosa hybrida
‘POULscots’.
Commercial: Shrub.
SUMMARY OF THE INVENTION
The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between ‘POULari’ described and illustrated in U.S. Plant Pat. No. 9,274 issued on Sep. 5, 1994 and ‘Mainzer Fastnacht’ (TANsi), an unpatented variety. The two parents were crossed during the spring of 1989 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘POULscots’.
The new rose may be distinguished from its seed parent, ‘POULari’, by the following combination of characteristics:
1. ‘POULscots’ exhibits lavender blooms; whereas ‘POULari’ exhibits white blooms.
2. ‘POULscots’ has fewer petals than ‘POULari’.
3. The blooms of ‘POULscots’ are borne singly, whereas ‘POULari’ exhibits multiple blooms per stem.
The new variety may be distinguished from its pollen parent, ‘Mainzer Fastnacht’ by the following combination of characteristics:
1. ‘POULscots’ exhibits lighter lavender blooms when compared to the pollen parent.
2. ‘POULscots’ has softer petals when compared to the pollen parent.
3. ‘POULscots’ has more glossy foliage than ‘Mainzer Fastnacht’.
The objective of the hybridization of this rose variety was to create a new and distinct variety for garden use with unique qualities, such as:
1. Uniform and abundant flowers.
2. Vigorous, but compact growth when propagated both as a budded rose and on its own roots;
3. Disease resistance.
This combination of qualities is not present in previously available commercial cultivars of this type and distinguish ‘POULscots’ from all other varieties of which we are aware.
As part of their rose development program, L. Pernille Olesen and Mogens N. Olesen germinated the seeds from the aforementioned hybridization during winter 1990 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.
‘POULscots’ was selected in the spring 1991 by the inventors as a single plant from the progeny of the aforementioned hybridization. Asexual reproduction of ‘POULscots’ by traditional budding and rooted cuttings was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in summer 1991. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULscots’ are true to type and are transmitted from one generation to the next.
