White Jacques Cartier – pharmaROSA® NEONATAL rooted cutting
White Jacques Cartier offers a historically anchored, own-root propagation option for specialist rose production where heritage value, scent impact and collection-grade authenticity matter. As a bush-trained, discreetly supported shrub with bushy structure and dense, matte dark foliage, it provides a premium basis for 5–7 litre container routes aimed at selection and specialty lines. The very strongly perfumed, classic rosette blooms and remontant habit underpin premium collector-focused product concepts in thematic and show gardens serving retail/collector channels. Own-root, tray-grown NEONATAL material supports stable, long-term stock with renewable shoots and predictable stand longevity, helping to secure homogeneous batches and capacity planning for UK nursery networks exposed to cold-winter conditions and wind-exposed northern sites where reliable H7 hardiness is a clear advantage. In practical production terms, year one sees rooting and framework establishment, year two delivers structural shoot build-up, and by year three the cultivar expresses its full ornamental value in finished form.

| Awards and recognition |
not provided |
| Growth and structural characteristics |
Bushy, upright shrub reaching about 80–130 cm in height and 70–120 cm in spread, with dense, matte dark green foliage and moderate prickliness; spent blooms are poorly self-cleaning and require manual removal. |
| Flower morphology |
Large, very double rosette blooms with more than 40 petals are produced mainly as solitary flowers; remontant flowering with a less abundant second flush, giving classic old rose presentation in premium shrub form. |
| Colour data and phenology |
Flowers open from cream-white buds with a pale pink flush to snow-white outer petals and slightly ivory inner petals; colour holds well, with occasional creamy or browned petal edges in heat and strong sun, RHS 155D/155C. |
| Fragrance and aroma |
Very strongly scented with a full old-rose, classic fragrance that can fill the surrounding area, giving the cultivar particular value for scented borders, specimen shrubs and collector-focused historic rose compositions. |
| Hip characteristics |
Forms moderately abundant, spherical red hips about 12–19 mm in diameter, adding visual interest in the later season where deadheading strategies allow fruit development after the main flowering period. |
| Resistance and winter hardiness |
Hardy to approximately -32 to -29 °C (H7, Swedish zone 5, USDA 4b), but disease resistance is modest with moderate susceptibility to powdery mildew and black spot and very high sensitivity to rust, requiring regular protection. |
| Horticultural recommendations |
Best used as a flower-border or park specimen, edging plant or cut-flower shrub in premium, specialty programmes; maintenance requirement is medium–high, with regular irrigation in dry periods and planned plant protection essential. |
White Jacques Cartier offers highly scented, historically significant shrubs with reliable hardiness on a predictable, regenerative own-root base, making it a considered choice for premium specialty production where we can align capacity and scheduling together.
