ABSTRACT:
SUMMARY OF THE INVENTION
The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between an unnamed seedling (non-patented) and
R. multiflora
‘Nana’ (non-patented)The two parents were crossed and the resulting seeds were planted in a controlled environment. The new variety is named ‘POULtumb’.
The new rose may be distinguished from its seed parent, unnamed seedling, by the following combination of characteristics:
1. The seed parent has small, deep pink colored flowers while ‘POULtumb’ has small white flower;
2. The seed parent is a floribunda rose with a bushy upright habit; whereas, ‘POULtumb’ is low growing with a more spreading habit.
The new variety may be distinguished from its pollen parent
R. multiflora
‘Nana’ by the following combination of characteristics:
1. The pollen parent is miniature rose; whereas, ‘POULtumb’ is a low growing shrub rose;
2. The pollen parent blooms recurrently for 8-10 weeks; whereas, ‘POULtumb’ blooms continuously throughout the growing season.
The objective of the hybridization of this rose variety for garden use was to create a new and distinct variety with unique qualities, such as:
1. Uniform and abundant flowers;
2. Vigorous, compact growth;
3. Disease resistance;
4. Continuous blooming.
This combination of qualities is not present in previously available commercial cultivars of this type and distinguishes ‘POULtumb’ 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. ‘POULtumb’, was selected by the inventors in the spring of 1987 as a single plant from the progeny of the aforementioned hybridization.
Asexual reproduction of ‘POULtumb’ by traditional budding was first done by L. Pernille and Mogens N. Olesen in August 1987 in a nursery in Fredensborg, Denmark. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULtumb’ are true to type and are transmitted from one generation to the next.
