Rosa spp. 'Climbing & Rambling Group'
climbing & rambling roses
Complex hybrid origin from species native to Northern Hemisphere temperate regionsOverview
Climbing and rambling roses encompass a diverse group of Rosa species and cultivars characterized by long, vigorous canes that can be trained on structures. These are not true vines — they do not twine, grip, or attach to surfaces — but produce long canes that must be tied to supports. The distinction between climbers and ramblers is functionally important: climbing roses typically produce stiffer, more upright canes 8-15 feet (2.4-4.6 m) long, with larger flowers that repeat bloom throughout the growing season on both old and new wood. Rambling roses produce longer, more pliable canes 10-20 feet (3-6 m) or more, with clusters of smaller flowers that bloom once in late spring to early summer on the previous year's wood only. Leaves are alternate, pinnately compound, with 5-7 (occasionally 9) serrate, ovate leaflets, glossy to semi-glossy. Most have thorns (prickles) along the canes in varying density. Flower forms range from single (5 petals) through semi-double to fully double (40+ petals), in colors spanning white, pink, red, yellow, orange, apricot, and bicolors. Many are fragrant. Fruit (hips) are fleshy, typically red to orange, ripening in fall; hip production is reduced by deadheading. In the Pacific Northwest, black spot, powdery mildew, and rust are persistent fungal disease concerns. Aphids and rose sawfly are common insect pests.
Native Range
Wild rose species are native across temperate regions of the Northern Hemisphere including North America, Europe, and Asia. Climbing and rambling rose cultivars are of complex hybrid origin, developed over centuries of breeding involving multiple species including Rosa multiflora (Japan), Rosa wichuraiana (East Asia), Rosa moschata (western Asia), Rosa gigantea (southeast Asia), and others.Suggested Uses
Trained on walls, fences, arbors, pergolas, trellises, and pillars. Climbing roses are suited to structures 8-15 feet (2.4-4.6 m) tall; ramblers can cover larger structures up to 20+ feet (6+ m). Space 6-10 feet (1.8-3 m) apart along a fence. Disease-resistant cultivars recommended for the Pacific Northwest include 'New Dawn' (climber, pale pink, repeat), 'Compassion' (climber, salmon-pink, repeat, fragrant), 'Sally Holmes' (climber, white, repeat), and 'Albertine' (rambler, copper-pink, once-blooming, fragrant).How to Identify

Bloom Information
Climbing roses bloom from May through October with repeat flushes, most heavily in June and September. Rambling roses bloom once, typically in June to July, for 3-5 weeks. In the Pacific Northwest, the first flush of climbing roses typically begins in late May to early June. Deadheading spent flowers on repeat-blooming climbers promotes subsequent flushes. Do not deadhead ramblers or hips will not form for fall and winter interest.Detailed Descriptions

Care & Maintenance
Care Guide
Water deeply 1-2 inches (2.5-5 cm) per week during the growing season, applied at the base to keep foliage dry. Plant in full sun with at least 6 hours of direct light and good air circulation. Requires fertile, well-drained soil amended with compost. Mulch 2-3 inches (5-8 cm) to conserve moisture and suppress weeds. Train canes horizontally or at an angle on supports to encourage lateral flowering shoots along the cane length; vertical canes flower only at the tips. Black spot, powdery mildew, and rust are persistent concerns in the Pacific Northwest; select disease-resistant cultivars when possible. Apply preventive fungicides in wet springs if needed. Fertilize monthly May through August with a balanced rose fertilizer; stop fertilizing by mid-August to allow hardening before winter.Pruning
Climbing roses: prune in late winter (February through March). Remove dead, damaged, and oldest canes (more than 4-5 years). Retain 4-6 vigorous main canes. Shorten lateral flowering shoots to 2-4 buds. Train main canes horizontally. Rambling roses: prune immediately after flowering in July. Remove oldest, flowered canes at the base and tie in vigorous new canes that will flower the following year. Do not prune ramblers in winter — this removes the wood on which next spring's flowers will form.Pruning Schedule
