Magenta

Shrub 

The shrub rose variety you described has the following characteristics:

Height: 150-180 cm (about 5-6 ft)

Width: around 120 cm (4 ft)

Foliage: medium dense, large dark green leaves

Flowers: borne in clusters of 5-10 per stem

Large, fully double

Cup-shaped, old-fashioned form when open

Lavender-purple in color, but can take on lilac, pinkish or coffee tones depending on weather and climate

Fragrance: strong, fruity

Bloom Time: repeat blooming all season until frost

Origin: bred by Reimer Kordes in Germany in 1954

Disease Resistance: very good (+++)

This sounds like a lovely, vigorous shrub rose with its large, fragrant blooms in shades of lavender and coffee, borne abundantly all season on a bushy plant. The strong disease resistance is also a plus. I would recommend this variety to anyone looking for a hardy, floriferous shrub rose for their garden.
