Abstract

A new and distinct variety of miniature rose plant, referred to by its cultivar name, ‘MEIHELIOT’, is disclosed. The new variety forms double, hot pink colored flowers. Dense, semi-glossy foliage is formed, which contrasts with the blossoms. A bushy growth habit is displayed. The new variety is well suited for providing attractive ornamentation in the landscape.

Description

Latin name of genus and species of plant claimed: Rosa hybrida.
Variety denomination: ‘MEIHELIOT’.
STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR
The first offer for sale of the new variety was Oct. 7, 2022, in the United States of America. The first offer for sale of the new variety was by the inventor or another who obtained the new variety directly or indirectly from the inventor. No plants of the new variety have been sold in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior the effective filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.
BACKGROUND OF THE INVENTION
The new variety of rose plant of the present invention was created by controlled breeding at Le Cannet des Maures, Var, France by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) of the new variety was the ‘MEIKANROU’ variety (U.S. Plant Pat. No. 9,973). The male parent (i.e., the pollen parent) was an unnamed seedling (not patented) which is the product of a cross between an unnamed seedling (not patented) and the ‘RADTKO’ variety (U.S. Plant Pat. No. 16,202).
The parentage of the new variety can be summarized as follows:
‘MEIKANROU’ X (Unnamed Seedling X ‘RADTKO’)
The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.
The new variety has been found to undergo asexual propagation in Le Cannet des Maures, Var, France by a number of routes, including eye budding, softwood cuttings, semi-hardwood cuttings, and hardwood cuttings. Asexual propagation by the above-mentioned techniques in Le Cannet des Maures, Var, France has shown that the characteristics of the new variety are stable and are strictly transmissible by asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.
SUMMARY OF THE INVENTION
It was found that the new variety of rose plant of the present invention possesses the following combination of characteristics:
    • (a) forms bright hot pink colored flowers,
    • (b) produces double flowers, and
    • (c) exhibits a bushy growth habit.
The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape.
The new variety of the present invention can readily be distinguished from its ancestors. More specifically, the ‘MEIKANROU’ variety (i.e., the seed parent) provides dark red colored flowers with typically between 65 to 85 petals, whereas the new variety provides hot pink colored flowers with typically between 40 to 50 petals. In addition, the unnamed seedling male parent (i.e., pollen parent) display flowers which are smaller and produce less petals compared to flowers of the new variety. Moreover, the new variety can be readily distinguished from other similar non-parental varieties. For example, the ‘MEIFERJAC’ variety (U.S. Plant Pat. No. 9,652) provides stable red colored flowers with approximately 27 petals on average, whereas the new variety provides hot pink colored flowers with typically between 40 to 50 petals.
The new variety has been named ‘MEIHELIOT’.
