Prickles:

On the main canes from the base there are normal quantity of prickles, approximately 9 on average per 10 cm of the stem length. There is also normal quantity of the prickles on the laterals from the main canes, approximately 14 on average per 18 cm of the stem length. The prickles are very elongated and longish-pointed on the upper surface, hooked on the under surface, and with a broad ovate and long base. The prickles have a length the of 1 cm on average and medium yellow brown colour (Group 164C).

Small prickles:

There are no small prickles on the main stalks and on the laterals from the main canes.

Disease resistance:

The rose variety ‘Garden Director Bartje Miller ’ / ‘Black Gold’ / ‘Eddy Mitchell’ has good disease resistance, particularly with respect to Oidium. Pest resistance has not been tested yet.

No particular tolerance to drought and cold has been observed for the new variety with the tolerance being generally comparable to other Hybrid Tea rose plants typically grown in parks and gardens. Rose variety is recommended for growing in climate conditions similar to USDA 6 and requires winter protection in more colder climates.

‘Garden Director Bartje Miller’ was named in honor of Bartje Miller, who was a garden director. This naming is a tribute to his contributions to horticulture and garden management.

Also this rose is marketed as ‘Eddy Mitchell’, born Claude Moine on July 3, 1942, in Paris, is a renowned French singer, songwriter, and actor1. He began his career in the late 1950s with the rock band Les Chaussettes Noires (The Black Socks), which quickly gained popularity. After going solo in 1963, he continued to achieve success, recording in various locations such as London, Memphis, and Nashville.

ORIGIN OF THE VARIETY

The rose variety ‘Meirysett’ / ‘Garden Director Bartje Miller ’ / ‘Black Gold’ / ‘Eddy Mitchell’ was created 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) was a product of the cross of the seed parent a Hybrid Tea rose ‘3-35-40 (Meilland/'Peace')’ / ‘Mme A. Meilland’ and the pollen parent Hybrid Tea rose ‘Meipsilon’ / ‘Yakimour'.

 The male parent (i.e., the pollen parent) was the Hybrid Tea rose ‘Delepi’ / ‘Epidor’.

The parentage of this rose variety can be summarized as follows:  (‘3-35-40 (Meilland/'Peace')’ / ‘Mme A. Meilland’ × ‘Meipsilon’ / ‘Yakimour') × ‘Delepi’/ ‘Epidor’.

BACKGROUND OF THE VARIETY

The seeds resulting from the above mentioned 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.

SUMMARY OF THE VARIETY

It was found that the ‘Meirysett’ / ‘Garden Director Bartje Miller’ / ‘Black Gold’ / ‘Eddy Mitchell’ rose plant has following unique characteristics:

 exhibits a semi-erect growth habit,

 abundantly forms attractive blossoms that are deep greyed-purple on the upper surface and ocher yellow on the under surface,

 forms attractive dark green foliage that is glossy on the upper surface,

 displays good tolerance to disease, and

 is well suited for growing as ornamentation in parks and gardens.

This rose well meets the needs of the horticultural industry and can be grown to advantage in the landscape where attractive ornamentation is desired. The flower coloration is considered to be rather unusual. The greyed-purple petal coloration on the upper surface is so dark that is sometimes appears to be almost black upon casual inspection.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and the use of cuttings. Asexual propagation by the above-mentioned techniques in France has shown that the characteristics of the variety are stable and are strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

COMPARISON WITH PARENTS

The new variety can be easily distinguished from its ancestors.

For instance, the blossoms of the ‘3-35-40 (Meilland/'Peace')’ / ‘Mme A. Meilland’ variety are golden yellow edged with rose pink.

The ‘Meipsilon’ / ‘Yakimour' variety forms cherry-red blossoms with a pale yellow reverse.

The ‘Delepi’/ ‘Epidor’ variety forms deep yellow blossoms.
