Habit
A spreading bush with arching canes; in warm climates it can grow much taller
Dimensions
1.2 m × 1.0 m in Europe; up to 2 m in hot climates
Support
Not required as a shrub; the climbing form (1968) suits an arch or trellis
Shoots
Sturdy, flexible, hold heavy clusters well
Branching
Dense; flowering canes form a broad, rounded bush

Fragrance

Light

Light, honey-sweet. Fragrance is not the variety's strong point; its main value is the number and purity of its flowers.

Disease resistance

4 out of 5
Black spotresistant

Important nuance: the variety held ADR 1960, but ADR was withdrawn in 2004 due to reduced resistance to black spot (after more than 40 years in cultivation the variety had accumulated problems). Even so, it remains one of the most robust classic floribundas.

Sun

Sun or light shade

Tolerates partial shade.

Thorns

How to grow

Where to plant. An almost UNIVERSAL variety, suitable for any design: all-white wedding beds, contrast to bright varieties, parks, borders, hedges; in warm regions, as a small climber on a south wall. Tolerates partial shade well.

Climate. Down to −29 °C. All of Ukraine with minimal protection; in the south, no protection needed. One of the hardiest floribundas.

Care. As a classic floribunda, prune in spring by about one third; since 2004 (loss of ADR) it needs seasonal black spot prevention 2 times a season in humid climates; removing spent blooms encourages new flushes.

About the name

Name. 'Iceberg' means 'iceberg' in English. A descriptive name that conveys the cool whiteness and the continuous, abundant flowering (like an iceberg made of blooms). In other languages the variety is sold under different 'snow' names: Schneewittchen® (German, 'Snow White'), Fée des Neiges (French, 'Snow Fairy'), Sneeuwwitje (Dutch, 'Snow White').

Breeding. Bred by Reimer Kordes (W. Kordes' Söhne, Sparrieshoop, Germany), 1958. Code KORbin. Parentage: 'Robin Hood' (Hybrid Musk, Pemberton 1927) × 'Virgo' (Hybrid Tea, Mallerin 1947). The Climbing-type form was found as a spontaneous sport by Cants of Colchester (England) in 1968; it is a separate variety with the same name. Reimer Kordes was the son of Wilhelm Kordes II and the father of Reimer-junior; he later bred 'Friesia' (1973), also a WFRS Hall of Fame variety.

Significance. One of the earliest varieties in the WFRS Rose Hall of Fame (WFRS HoF, 1983), third after Peace (Meilland 1945) and Queen Elizabeth (Lammerts 1954). Other honours: RNRS Gold Medal 1958, ADR 1960 (withdrawn 2004, a nuance), RHS Award of Garden Merit 1993. One of the best-known white varieties of the twentieth century and still a top seller worldwide. In our catalogue it is an important parent line: Iceberg is the parent (through the Wife of Bath line) of several legendary Austin English Roses: Heritage (1984), Mary Rose (1983), Wife of Bath (1969), Gertrude Jekyll (1986). Without Iceberg, English Roses would not look the way we know them.
