TANrezlaw – Schneewalzer climbing rose propagation material
Vertical production with TANrezlaw supports an exclusive, space‑defining climber offer built on large, exhibition‑grade white blooms and a cut-flower style, high‑centred bud form that reads well in premium ranges. As pharmaROSA® NEONATAL own‑root material, these tray‑grown, 3–6‑month‑old cuttings give you a predictable base for trained climber lines, with staked, pre‑trained 3–5 cane finished plants in 5–7 L containers or larger 40–50 litre landscape units for pergolas, façades and trellis projects. In UK nursery conditions you can rely on steady heat and drought tolerance suited to warmer southern and south‑eastern sites with regular irrigation, while the own‑root structure underpins long‑term vertical features with low replacement in thematic and collection plantings. From year‑on‑year scheduling, you can plan Year 1 rooting, Year 2 structural shoots and Year 3 full ornamental effect into public‑realm or retail/reseller programmes. The sparsely thorned canes, glossy dark green foliage and premium‑gold cultivar rating help maintain consistent presentation, supporting wholesale partners seeking stable, professional climber supply and collection builders requiring verified identity and traceable provenance.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Registered as TANrezlaw, marketed as Tanrezlaw Climbing rose TANrezlaw, exhibition name Schneewalzer; large-flowered climbing rose in the Climbing rose commercial group and climber commercial type. |
| Origin and breeding |
Bred by Hans Jürgen Evers, Rosen Tantau, Germany, with introduction, breeding and registration all in 1987; parentage is unknown but distributed initially by Rosen Tantau. |
| Awards and recognition |
Awarded a Certificate of Merit at the New Zealand Rose Trials in 1991, supporting its positioning as an exhibition-capable climbing rose within premium, collection-focused ranges. |
| Growth and structural characteristics |
Climbing habit with 200–320 cm height and 120–220 cm spread, sparsely thorned canes and moderately dense, glossy dark green foliage; weak self-cleaning, so spent blooms often require manual removal. |
| Flower morphology |
XL solitary flowers, semi-double with 13–25 petals, high-centred and pointed-budded reminiscent of cut roses; remontant with a strong second flush, supporting extended decorative or cutting periods. |
| Colour data and phenology |
Delicate white to near-white flowers with creamy to lemon-yellow tones fading to ivory; ARS code W, RHS N155C outer and 8D inner; moderate colour retention with elegant, gradual lightening during opening. |
| Fragrance and aroma |
Medium-strength, light citrus fragrance offering a fresh scent profile; semi-double form and reduced stamen accessibility limit pollinator value, making it only partially attractive to beneficial insects. |
| Hip characteristics |
Rose hips set sparsely due to flower form; when present, hips are ovoid, 9–15 mm in diameter and orange-red, offering only limited decorative value and minimal impact on production planning. |
| Resistance and winter hardiness |
Medium resistance to powdery mildew, black spot and rust; hardy to approximately −21 to −18 °C (H7, Swedish zone 3, USDA 6b) with good heat tolerance if regularly watered in dry spells. |
| Horticultural recommendations |
Best used for pergolas, rose arches, façades, trellises and as a cut-flower-capable climber; medium maintenance with occasional pest control, supplied as staked, trained 3–5 cane climbers in 5–7 L pots. |
TANrezlaw offers large exhibition-grade white blooms, reliable heat-tolerant vertical growth and own-root longevity that stabilises climber stands, providing a solid option for partners planning capacity and seeking to align future schedules and quotations.
