Rosa Sirius ='TAN05415' (F)

Common name: Floribunda Rose 'Sirius'

Description: Rosa 'Sirius' is a charming and award-winning Floribunda rose from Tantau that has earned ADR certification — Germany's most rigorous and respected independent rose quality award — for its exceptional combination of floriferousness, disease resistance, and easy-going constitution. The medium-sized, double, cup-shaped flowers open in clusters of considerable generosity in a delicate, warm soft apricot, fading gracefully to the purest white as the blooms mature, creating a subtle and luminous two-tone effect within each truss that gives the plant a quiet, refined elegance of great charm. The pale, pearlescent colouring is particularly beautiful in evening light and associates superbly with soft blues, lilacs, and silver foliage plants, as well as providing a gentle and harmonious companion to bolder-coloured roses in a mixed planting. Flowers are self-cleaning and produced continuously and prolifically from early summer through to the first frosts of autumn, ensuring a long and sustained season of understated but genuinely lovely colour. The bushy, vigorous plant is well clothed in very healthy, glossy foliage with outstanding disease resistance, making 'Sirius' one of the most reliable and low-maintenance Floribundas available for the British garden.
