TITIAN™ – deep pink climbing rose - Riethmuller
Climbing TITIAN™ offers professional growers a distinctive own-root propagation base for trained vertical features and pillar applications, with a remontant flowering habit and medium-maintenance profile suited to nursery workflows and UK project timelines. Its vigour and dense, dark green foliage support space-defining, exclusive finished products in the 5–7 L staked, pre-trained climber segment, while good winter hardiness allows reliable outdoor production, including regions where winter and wind exposure are more demanding. The rich, carmine-pink colour range with rosette, cluster-flowered blooms and a fragrant yet not overpowering profile gives wholesalers a versatile SKU for premium retail/reseller assortments. Own-root production underpins long-term stability in stock blocks and collection plantings (Year 1 roots, Year 2 structural shoots, Year 3 full ornamental value), with predictable regeneration and low replacement risk across integrated nursery networks and public-realm supply chains.

| Origin and breeding |
Bred by Francis Lewis Riethmuller in Australia, 1955; parentage ‘Crimson Glory’ × ‘Eutin’; introduced by Hazlewood Bros. (Australia, 1955) and W. Kordes’ Söhne (Germany); first introduction around 1950. |
| Awards and recognition |

| Growth and structural characteristics |
Vigorous climbing habit to 240–400 cm high and 160–260 cm spread; dense, matt dark green foliage; moderately thorny canes; moderate self-cleaning so occasional deadheading is advisable in production. |
| Flower morphology |
Double rosette blooms with 26–39 petals; medium flower size around 1.5–2.75 inches; cluster-flowered inflorescences; remontant with an abundant second flush, supporting extended ornamental use under management. |
| Colour data and phenology |
Rich deep-pink with subtle carmine tint; ARS code dp, RHS 53A outer and 53B inner; colour brightens in cooler weather and pales slightly in strong sun; stages from glossy purple-pink buds to silvery-edged raspberry tones before fading. |
| Fragrance and aroma |
Clearly perceptible, medium-strength fragrance with a fresh tea character and subtle fruity notes; primarily ornamental with limited pollinator access due to the full, double flower form and reduced stamen exposure. |
| Hip characteristics |
Occasional ellipsoid hips, approximately 10–15 mm diameter, orange-red at maturity; hip production is sporadic and not the primary ornamental or commercial focus of this climbing cultivar. |
| Resistance and winter hardiness |
Hardy to approximately -32 to -29 °C (USDA 4b, Swedish Zone 5, RHS H7); medium resistance levels to powdery mildew, black spot and rust, generally manageable under standard professional nursery protection regimes. |
| Horticultural recommendations |
Recommended for flower beds, borders, parks and urban green spaces as a vertical accent; medium maintenance with occasional pest and disease control; best supplied as staked, trained climber in 5–7 L containers. |
