Variety description

10 August 2026

A hybrid tea variety characterized by a vigorous, upright bush with a height of 100 to 175 cm and a width of about 125 cm. New shoot growth has a characteristic crimson hue. Shoots are strong, resistant to lodging, and flowers are primarily situated singly at the ends of the stems.

Flowers are of classic goblet shape, large (10–12 cm in diameter), double, with 25 to 45 petals. The color varies from cream and ivory to soft apricot and peach tones; pale pink shades may appear upon full opening. The variety possesses a distinct fruit fragrance of medium intensity.

The plant is repeat-flowering. In regions with cold climates, it requires winter protection. Data regarding disease resistance varies: both healthy foliage and susceptibility to powdery mildew and black spot are noted. Petals are resistant to precipitation.
