Rose Mistinguett

Rich red Nostalgic hybrid tea rose with a special flair. The large flowers are a brilliant shade of red. Their shape starts off globular before turning cup-shaped with the popular nostalgic flowers twist. The dark reddish-green, very glossy foliage is exceptionally healthy, the long-stemmed flowers are particularly well suited for cut flowers. ‘Piano’ has a very long flowering period, right until the frosts.

Nostalgic

‘Piano’ / ‘TAN01360’ originated by crossing the variety ‘RT98097’ (seed parent), with the variety ‘Mein München’ (pollen parent) by Anne G. Cocker, 1987.

BACKGROUND OF THE INVENTION
The primary objective of this breeding was to produce a new 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: 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’ / ‘Red Leonardo da Vinci’ in plant height (100–130 cm tall for ‘TAN01360’ versus 40–60 cm tall for ‘Meiangele’ / ‘Red Leonardo da Vinci’).
