More information
One of the most widely grown roses worldwide, with ongoing discussion about whether it is a pink or a white rose, and whether it belongs to the hybrid tea or floribunda group. In cool climates the blooms are pale pink, and in hot climates they are pure white. Flowers appear more singly in early summer, then in large clusters at the second flush. Individual blooms are large and refined, opening from high-centred, classic buds. As they develop, the buds become cup-shaped, as in floribundas, with red stamens in the centre. At close range the pollen is grey, an uncommon trait in roses. The petals are distinctly curved, yet dense and rain-resistant. The shrub is tall, vigorous, upright, and disease-resistant, with large, glossy foliage. In hot climates it reaches 2.5 m and can flower for up to 12 months of the year.
This rose flowers in small sprays of very pale pink, almost white blooms. Buds open to wavy petals surrounding a tightly twisted centre, which later opens to show golden stamens. The fragrance is strong, and stems hold well when cut. The bush is sturdy and upright, with dark green foliage, reaching 75 cm. Flowering is prolonged. Tolerant of heat and rain.
Blooms are white with a pearly pink tint at the centre. The intensity of pink varies with weather; by full opening the blooms are pure white. The colouring stands up to adverse weather; heavy rain scarcely affects the flowers. The blooms open in three clearly distinct stages. First: a pointed bud suitable for cutting. Second: a tall centre remains, surrounded by petals. Third: the centre opens, revealing the stamens. The scent is light, reminiscent of rose oil. Flowers are borne in small clusters, with bloom production not heavy. The bush branches little; new shoots arise mainly from the base, so it is more compact and squat than usual. Reaches 110 cm in height and 60 cm in width. Foliage is dark green, glossy, and sparse, with lower stems becoming bare. Can be affected by black spot.
This floribunda has received many awards, including for the fragrance of its double flowers. Newly opened buds are conical, later becoming cup-shaped. Petals are initially pearlescent white, then turn salmon-pink. The bush is upright, well branched, and covered with fresh green foliage.
A white floribunda, very similar to Iceberg, with the distinction that Margaret Merill is fragrant. The variety has won many awards. Disease-resistant, fast-growing, and larger than Iceberg.
