Plant size

135–215 × 60–90 cm

Habit: Tall, upright, vigorous bush — inherits its vigour from the parent 'Peace'
Dimensions: 135–215 cm tall × 60–90 cm wide
Support: No support needed — a standard HT, holds its tall shape on its own
Shoots: Sturdy, straight, holding the large flowers well on long stems
Branching: Moderate, typical of HTs; the shoots spread well from the base

Flower

13–15 cm

Bud shape: Elongated, pointed, tall — the classic HT bud of the Peace family
Open flower: High-centred, opening into a cupped flower with wide wavy petals; diameter 13–15 cm — very large
Centre: Canary-yellow base to the petals; the pink gradually 'eats into' the yellow as the flower ages
Fullness: Very double, 45–60 petals
Flower carriage: Mostly large flowers borne singly on each stem

Fragrance

Light, fruity.

How to grow

Where to plant. Formal borders, cut-flower roses, the centre of a large flower bed; because of its large tricolour flowers it works as a specimen plant or an accent.

Climate. To −18 °C — less hardy than the parent 'Peace'; in the northern and central regions of Ukraine winter protection is essential. In the south, no protection is needed in mild winters.

Care. Classic HT — formative pruning in spring, regular preventive fungicide treatments (especially against black spot). The sport is unstable — shoots in the 'Peace' colour may appear on the bush; it is best to remove them.

About the name

Name. After the city of Chicago (Illinois, USA), where the sport was found at the Conard-Pyle nursery. 'Peace' — from the parent rose 'Peace' (Meilland 1935), which symbolises peace after the Second World War.

Breeding. A spontaneous sport of the legendary 'Peace' (Meilland 1935), found by Stanley C. Johnston at the Conard-Pyle nursery (USA) around 1956–1960. Introduced in 1962 (Star Roses, USA). Patent code — JOHnago.

Significance. The best-known sport of the legendary 'Peace'. Its colours are much brighter and richer than the parent. Awarded the Portland Gold Medal (1962). It became the 'parent' of later sports: 'Don Charlton' (1991) and 'Desert Peace' (1991).
