Alchymist® Climbing rose Kordes – pharmaROSA® NEONATAL rooted cutting
The pharmaROSA® NEONATAL own-root cuttings of Alchymist® are designed as a professional foundation for trained climber production, supporting stable, long-term stock for pergolas, walls and space-defining park structures. As a vigorously climbing, densely foliaged rambler-type rose with glossy, mid-green leaves and strong framework growth, it is well suited to 5–7 L container production as a staked, pre-trained feature for vertical garden projects and landscape schemes. The once-flowering, richly double, rosette blooms deliver a concentrated, seasonal display of colour transition from deep yellow through peach to softer apricot tones, paired with a very strong, fruity-honeyed fragrance that enhances presentation in thematic and collection gardens. With own-root plants supporting long lifespan, regeneration and homogeneous stands, Alchymist® can underpin reliable capacity planning for nurseries and integrator networks, including public-realm and institutional supply where distinctive climbing elements are required in regions where winters are reliably tolerated even in colder, exposed parts of Scotland and northern England.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Current trade name Alchymist® Climbing rose Kordes; exhibition name Alchymist; unregistered variety with no separate registered cultivar name; commercial type rambler, climbing rose; authenticity verified 27.10.2025. |
| Origin and breeding |
Bred by Reimer Kordes, W. Kordes’ Söhne, Germany, from cross ‘Golden Glow’ × Rosa eglanteria L. hybrid; breeding and introduction around 1956; initially distributed by W. Kordes’ Söhne. |
| Growth and structural characteristics |
Strongly climbing habit, reaching approximately 300–450 cm in height with 150–250 cm spread; dense, mid-green glossy foliage; densely thorned canes; weak self-cleaning so spent blooms often require manual removal. |
| Flower morphology |
Very double rosette flowers with more than 40 petals; generally small size around 0.5–1.5 inches in diameter; solitary blooms; non-remontant, producing a single main flowering period rather than repeating through the season. |
| Colour data and phenology |
Apricot overall effect with deep radiant yellow to soft peach transitions; ARS code ab, RHS 14B outer and 23A inner; colour fades in strong sun and heat but stays deeper in cooler conditions, giving a changing, alchemist-like display. |
| Fragrance and aroma |
Very strongly scented cultivar with rich fruity-honeyed character, noticeable from a distance; highly ornamental but tightly closed, very double flowers keep stamens concealed and offer limited pollinator access compared to simpler forms. |
| Hip characteristics |
Fruit set is generally modest; where formed, hips are ovoid to egg-shaped, orange-red in colour, around 12–18 mm diameter, adding some seasonal interest but not a primary feature of the cultivar. |
| Resistance and winter hardiness |
Hardy to approximately -32 to -29 °C, RHS hardiness H7, Swedish zone 5, USDA zone 4b; moderate tolerance of powdery mildew and black spot; very sensitive to rust, requiring regular monitoring and protective disease control in production. |
| Horticultural recommendations |
Best used as a climbing rose for pergolas, fences, walls, specimen and park plantings; maintenance requirement high with weak self-cleaning and disease susceptibility; needs regular care, staking, and training for quality finished climber products. |
