New Dawn climbing rose
Garden origin, United States (species: eastern Asia)
Overview
Rosa 'New Dawn' is a repeat-flowering climbing rose patented in the United States in 1930 as a sport of R. 'Dr. W. Van Fleet'. Canes reach 10–15 feet (3–4.5 m) in length and spread 6–10 feet (1.8–3 m), and they are stiff but arching, so they require a trellis, wall, or fence for support. Flowers are pale blush pink, 3–3.5 inches (7.5–9 cm) across, with about 25 petals in a cupped to semi-double form that fades to nearly white in sun. Blooms open in clusters of 3–10 and carry a light apple fragrance. Leaves are pinnate with 5–7 leaflets, each 1.5–2.5 inches (4–6 cm) long, glossy and medium to dark green. Canes carry curved prickles 0.25–0.5 inch (6–12 mm) long. Plants are hardy in USDA zones 5–9. Foliage is more resistant to blackspot than most roses, and canes freeze back to the snow line in some zone 5 winters. Each flush lasts 3–4 weeks, and the first is heaviest.
Native Range
Rosa 'New Dawn' is a garden cultivar that arose in the United States as a sport of R. 'Dr. W. Van Fleet', a hybrid of R. wichurana. The species R. wichurana is native to eastern China, Japan, Korea, and Taiwan.Suggested Uses
Used on arbors, pergolas, walls, and fences, with canes trained to 10–15 feet (3–4.5 m), and as a large shrub when pruned to 5–6 feet (1.5–1.8 m). Spaced 8–10 feet (2.4–3 m) apart along fences. Cut flowers last 3–5 days in water.How to Identify

Care & Maintenance
Care Guide
Plants grow in full sun to part shade, with at least 4–6 hours of direct light, in fertile, well-drained loam with a pH of 6.0–6.5. Water is applied at 1–2 inches (25–50 mm) per week at the soil surface. Canes are tied to a support at 12–18 inch (30–45 cm) intervals and arched horizontally to increase flowering shoots along their length. A balanced rose fertilizer is applied in early spring and after the first flush. Hardiness covers USDA zones 5–9. Plants tolerate part shade but flower less than in full sun, and growth is vigorous enough to overwhelm small supports.Pruning
Pruning is done in late winter or just after the first flush, removing dead, weak, and crossing canes at the base. Side shoots that flowered are shortened to 2–3 buds, and 3–5 main canes are kept and tied in. Spent flowers are cut back to the first five-leaflet leaf for repeat bloom.Pruning Schedule
Prune: February–March
