When it comes to climbing roses, ‘Zephirine Drouhin’ is one of the most versatile. It’s a thornless, shade-tolerant rose that unfurls deep pink blooms. Thorn-free canes make this a great rose to place on arches or pergolas over walkways or patios. ‘Zephirine Drouhin’ opens intensely fragrant flowers from spring to fall frost. This antique rose was officially introduced in France in 1873. Plants grow to 12 feet tall and 3 to 6 feet wide. Hardy in Zones 5-9.
