USPP20621P2 - Floribunda rose plant having large flowers and named ‘TAN01360’ - Google Patents

Abstract

Floribunda rose plant having large ball shaped, bright red flowers and healthy foliage.

Description

Genus and species: Rosa hybrida.

Variety denomination: ‘TAN01360’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a large-flowered floribunda rose plant named ‘TAN01360’ which was originated by me by crossing the variety ‘RT98097’ (seed parent), with the variety ‘Mein München’ (pollen parent).

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new floribunda rose variety having large, ball shaped, bright red flowers and healthy foliage.

BRIEF SUMMARY OF THE INVENTION

The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

• • 1. Very nice ball shaped flowers.
  • 2. Bright red flower.
  • 3. Healthy foliage.
    This new variety is a good garden rose variety for private gardens, parks and landscaping.

Asexual reproduction of this new variety by grafting, as performed at Uetersen, Germany, shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

Comparison with Parents

The new variety ‘TAN01360’ differs from the seed parent, RT98097, in classification, (‘TAN01360’ is classified as a floribunda grandiflora (nostalgic hybrid tea) while RT98097 is classified as a hybrid tea). The pollen parent has a yellow-orange flower color.

Comparison with Similar Variety

‘TAN01360’ differs from ‘Meiangle’ in plant height (60–80 cm tall for ‘TAN01360’ versus 40–60 cm tall for ‘Meiangele’).

BRIEF DESCRIPTION OF THE ILLUSTRATION

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

DETAILED BOTANICAL DESCRIPTION
