Variety description

10 August 2026

The plant forms a rounded bushy habit with a height and width of 90–120 cm. Young foliage has a burgundy hue, which changes to dark green over time. The flowers, 5–6 cm in diameter, are single and consist of 5–7 petals that lighten as they fade.

The variety blooms abundantly and almost continuously from late spring until frost, without the need for deadheading. The plant is characterized by high resistance to black spot, powdery mildew, and rust, as well as good winter hardiness in USDA zones 5–11. The scent of the flowers is practically absent.

This variety is intended for landscaping, including the creation of hedges and use in mass plantings. The plant is not a cut rose and does not maintain freshness in a vase for long.
