Emeraude d'Or – Hybrid tea rose – DELrop
Professional own‑root NEONATAL material of Emeraude d’Or offers a stable basis for premium hybrid tea production, with its upright, very bushy habit and strong, solitary exhibition blooms suited to flowerbed, specimen and park use. Double, large‑flowered, golden‑yellow to carmine‑pink colour transitions deliver consistent flower quality and form for exclusive finished product ranges, aligning with premium container routes in 5–7 L, and supporting nursery networks where reliable, medium‑maintenance cultivars are required in regions facing winter and wind exposure typical of parts of Scotland and northern England. Own‑root trays at 3–6 months integrate efficiently into professional workflows, allowing You to plan rooted cuttings into bush‑trained, 3–5 cane structures for an exclusive, retail‑ready profile, building towards the natural development arc in which roots establish first, shoots consolidate in the second year, and full ornamental value expresses in the third season, while medium disease resistance and predictable hardiness help underpin long‑term, collection and project‑scale planting strategies.

| Awards and recognition |

| Growth and structural characteristics |
Upright, very bushy hybrid tea with moderately dense, slightly glossy dark green foliage tinged bronze; height 140–180 cm, spread 100–140 cm; moderately thorny shoots suitable for structural bush training. |
| Flower morphology |
Double, solitary, large hybrid tea blooms (26–39 petals, 2.75–3.95 in) with cup‑shaped form on medium‑height growth; remontant habit delivering a plentiful second flowering; weak self‑cleaning so spent blooms persist and need removal. |
| Colour data and phenology |
Vibrant golden‑yellow base with pale pink veiling and edges; buds deep amber yellow; colour shifts through apricot and fuchsia to deep carmine and crimson‑red with creamy and beige edging as flowers age; ARS YB, RHS 14A outer, 45B inner. |
| Fragrance and aroma |
Fragrance strength very weak and barely noticeable, with a delicate, rose‑like character; pollinator attraction limited as the 26–39 petalled double form partly conceals stamens and reduces accessibility. |
| Hip characteristics |
Rose‑hip set generally sparse owing to double flowers; when formed, hips are spherical, orange‑red, around 14–22 mm in diameter, adding minor seasonal interest without being a primary production trait. |
| Resistance and winter hardiness |
Medium overall disease resistance with medium susceptibility to powdery mildew, black spot and rust; hardy to about −21 to −18 °C, RHS H7, Swedish zone 3, USDA 6b; no specific data on heat or drought tolerance provided. |
| Horticultural recommendations |
Primary uses in flowerbeds, specimen and park plantings; medium maintenance with occasional pest and disease control; recommended as bush‑trained with 3–5 framework canes, routed into premium container production, target 5–7 L. |
