CHÂTEAU D´AMBOISE – dark red hybrid tea rose - Delbard-Chabert
Built for professional premium production, CHÂTEAU D´AMBOISE in pharmaROSA® NEONATAL form offers a stable own-root foundation for high-end hybrid tea ranges where controlled quality and identity are critical. This compact, erect, bush-trained material with 3–5 strong canes supports predictable shaping into 5–7 L containers as a premium container route, aligning with exclusive finished-product positioning and retail / reseller channels focusing on flower form and quality. Dark, glossy foliage frames the double, exhibition-type blooms, whose excellent colour retention ensures consistently marketable heads across successive flushes; the long-term own-root base contributes to homogeneous stands, lower replacement need and reliable renewal over multiple cropping cycles. Across UK nursery systems this cultivar fits well where reliable winter performance and wind tolerance are needed in northern and exposed plantings, supporting thematic rose gardens and collection projects that demand durable, named cultivars for long-term display value. From year 1 root establishment, through stronger year 2 shoot development, towards full ornamental expression from year 3, you gain a predictable production arc that is straightforward to schedule for premium launches and seasonal colour peaks in coordinated programmes.
