The English Musk Roses are notable for the perfection of their flowers and ‘Tranquillity’ lives up to this reputation. The flowers are of a beautifully rounded shape with neatly placed petals, making up a perfect rosette. The opening buds are lightly tinged with yellow but as the flowers open they become pure white. There is a light apple fragrance.The growth is upright, gradually curving outwards at the top. It has typical light green Musk Rose foliage and is almost thornless.
