CHANDON ROSIER – hybrid tea rose propagation material for premium containers
Exhibition presentation and premium cut-flower potential define CHANDON ROSIER for professional growers seeking colour-driven, florist-grade buds in an upright hybrid tea format that suits 5–7 litre, container-focused production and exclusive retail channels. Dense, dark green foliage supports the high-centred, pointed-bud flower form valued in the cut-flower and show arena, while own-root regeneration gives predictable, renewable growth that stands up well to nursery-level propagation loads over successive cycles. Working from tray-grown pharmaROSA® NEONATAL material enables you to synchronise planting, pruning and bench space, with year one root establishment, year two structural shoots, and year three delivering full ornamental value, aligning with planned premium releases. This cultivar offers a stable, long-lived base for thematic rose gardens and collection-style projects, particularly where deep red, silver-backed blooms need to perform reliably in beds and containers across regions that experience cold, windy winters and exposed conditions.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Hybrid tea rose, registered as DELatur, traded as Chandon Rosier Grands Coloris DELatur, with Alleluia as the American Rose Society approved exhibition name for show and competition purposes. |
| Origin and breeding |
Bred by Georges Delbard in France in 1980 from a complex hybrid involving Impeccable, Papa Meilland, Gloire de Rome and Corrida, with initial distribution via Wagner’s Rose Nursery in Australia. |
| Awards and recognition |
Recognised with Certificat de Mérite at Bagatelle, Paris in 1980 and later major show awards including King of Show in Kansas City (2001) and Court of Show in the Golden Triangle Rose & Garden Society Show. |
| Growth and structural characteristics |
Upright bush reaching about 100–140 cm high with 50–70 cm spread, dense dark green glossy foliage and moderate prickliness, forming a well-structured framework suitable for bush training from 3–5 main canes. |
| Flower morphology |
Medium-sized, double, 26–39 petal hybrid tea flowers, solitary on stems, with high-centred, pointed buds typical of exhibition and cut-flower types, flowering remontantly with a clearly abundant second flush. |
| Colour data and phenology |
Deep, velvety red petals (ARS RB; RHS 53A outer, 155C inner) with silver-pink reverses; colour lightens slightly in strong sun to warm burgundy while the backs become creamier, maintaining an attractive play of light. |
| Fragrance and aroma |
Moderate, clearly perceptible scent combining spicy and fruity notes, providing a distinct aromatic character which supports use in fragrance-led assortments despite its primary ornamental and exhibition orientation. |
| Hip characteristics |
Hip set is typically low due to the double flower form, though when present it forms small spherical orange-red hips around 10–14 mm diameter, offering only limited value for decorative fruiting displays. |
| Resistance and winter hardiness |
Moderate tolerance to powdery mildew, black spot and rust under standard management; hardiness around -15 to -12 °C (RHS H6, Swedish Zone 2, USDA 7b) supports use in temperate climates with typical winter protection. |
| Horticultural recommendations |
Suitable for beds, containers, specimens and garden cut-flower use; moderate maintenance with occasional pest and disease control, weak self-cleaning so spent blooms require removal to maintain display and plant health. |
CHANDON ROSIER offers exhibition-grade flower form, dense glossy foliage and award-backed appeal on a stable own-root base that supports predictable long-term stands and regeneration, making it a considered option for aligned capacity planning and scheduling discussions.
