Abstract
A new garden rose plant which has abundant, double, coral pink flowers and attractive, disease resistant foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.
Description
The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing in the summer of 1990 between an unnamed seedling and Bonica 82. The resulting seeds were planted in a controlled environment. The new variety is named ‘POULalo’. The new rose may be distinguished from its seed parent, an unnamed seedling, characteristics:
1. The unnamed seed parent is a ground cover rose with bushy and spreading growth, whereas ‘POULalo’ is a tall, bushy shrub with slightly arching canes; and
2. The unnamed seed parent has pink semi-double flowers, while ‘POULalo’ has coral pink double flowers in large clusters.
The new variety may be distinguished from its pollen parent, Bonica 82 created by the same inventors, by the following combination of characteristics:
1. The pollen parent has soft pink flowers which are 60 mm in diameter with 35 to 40 petals while ‘POULalo’ has coral pink, high centered, very double flowers which are 55-60 mm in diameter with 60-70 petals; and
2. The pollen parent is bushy and somewhat compact, while ‘POULalo’ is a tall, bushy shrub with slightly arching canes.
The objective of the hybridization of this rose variety for nursery and garden use was to create a new and distinct variety with unique qualities, such as:
1. Abundant, coral pink flowers;
2. A tall growing shrub rose with uniform growth and a spreading habit;
3. Glossy and disease resistant foliage which requires limited maintenance, making it ideal for use in landscapes; and
4. Good growth on its own roots as well as a traditionally budded plant.
This combination of qualities is not present in previously available commercial cultivars of this type and distinguish ‘POULalo’ 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 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.
‘POULalo’ was selected by the inventors in the spring of 1991 as a single plant from the progeny of the aforementioned hybridization.
Asexual reproduction of ‘POULalo’ by traditional budding was first done by L. Pernille and Mogens N. Olesen in August 1991, at their nursery in Fredensborg, Denmark. Other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULalo’ are true to type and are transmitted from one generation to the next.
The accompanying color illustration shows as true as is reasonably possible to obtain in color photographs of this type, the typical characteristics of the buds, flowers, leaves, stems, and a plant of ‘POULalo’. Specifically illustrated in SHEET 1:
1. Stem or entire plant showing branching and the attachment of leaves, buds, and peduncles;
2. Flower bud, partially opened bud, and open bloom;
3. Flower petals, detached;
4. Sepals, receptacle, and pedicel;
5. Flowering stem as well as a bare stem exhibiting thorns;
6. Leaves.
The following is a description of ‘POULalo’, as observed in its outdoor growth in a field nursery in Jackson County, Oreg. Observations were conducted during August 1991, using The Royal Horticultural Society (London, England) Colour Chart, 1995, except where common terms of color are used. For a comparison, several physical characteristics of the rose variety ‘POULfan’, a rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 9,641 and issued on 10 Sep. 1996 are compared to ‘POULalo’ in Chart 1.
