This is a rambler with reliable repeat bloom and decent fragrance. Flowers are semi-double (9-16 petals), about 1.5" across, cupped bloom form, in large clusters.

Color is usually described as mauve, but is often nearly magenta/purple. This plant has been described as a repeat-blooming 'Veilchenblau.'

This is highly resistant to black spot, and can be grown no-spray here (Boston Z6a) without defoliating. Won an ADR (All-Germany sustainable rose trials [no-spray]) in 2013.
