It showed the above average resistance to powdery mildew (Sphaerotheca pannosa), rust (P. disciflorum), blackspot (Diplocarpon rosae), and botrytis (Botrytis cinerea) diseases under normal growing conditions.

Unfortunately we do not have information about the origin of the name of this rose.

ADR 2016 and Best of the Best in La Tacita.

BACKGROUND OF THE VARIETY
A climbing rose ‘Florentina‘ is originated from a controlled crossing in a breeding program of two distinct parents during the summer of 2002. The crossing was between an un-named seedling, the seed parent, and another un-named seedling, the pollen parent, from the same inventor.

The resulting seeds were planted during the following winter. The resulting seedlings were evaluated and exhibited distinctive physical and biological characteristics. The new rose plant was selected as a single plant from the seedling beds due to its superior characteristics and asexually propagated for further evaluation. This new and distinctive rose variety is named ‘KORtrameilo’ / ‘Florentina’.

SUMMARY OF THE VARIETY
The objective of the hybridization was to create a new and distinct rose plant with unique qualities, such as:

1. Uniform growth and flowering;

2. Abundant attractive, recurrent flowers;

3. Attractive and abundant foliage; and

4. Resistance to diseases encountered in landscapes and gardens.

This combination of qualities is not present in prior rose cultivars known to the inventor. These objectives have been substantially achieved and in that distinguish ‘KORtrameilo’ from all other varieties.

As part of a rose development program, Tim-Hermann Kordes germinated seeds from the aforementioned hybridization and conducted evaluations and observations on the resulting seedlings in a controlled environment in Offenseth-Sparrieshoop, Germany. The resulting seedlings exhibited distinctive physical and biological characteristics. The new rose plant ‘KORtrameilo’ was selected in May, 2003 from the seedling beds to be asexually propagated for further evaluation. The first asexual propagation of ‘KORtrameilo’ was done by budding to seedling understocks in July, 2003 at the inventor's nursery in Offenseth-Sparrieshoop, Germany. This initial and other subsequent propagations conducted in controlled environments demonstrate that ‘KORtrameilo’ reproduces true to type in successive generations of asexual reproduction.

COMPARISON WITH PARENTS
The new rose plant may be distinguished from its seed parent, an un-named seedling, by the following combination of characteristics:

1. ‘KORtrameilo’ has very double medium red flowers, whereas the un-named seedling has semi-double dark red flowers.

2. ‘KORtrameilo’ has better disease resistance than the un-named seedling.

The new rose plant may be distinguished from its pollen parent, an un-named seedling, by the following combination of characteristics:

1. ‘KORtrameilo’ has large flowers and a climbing growth habit, whereas the un-named seedling has medium sized flowers and a bushy growth habit.

2. ‘KORtrameilo’ has excellent disease resistance, whereas the un-named seedling only has moderate disease resistance.
