Rosa 'Zephirine Drouhin' (or 'Zéphirine Drouhin') is a cherry-pink Bourbon rose, famous for being completely thornless. It was developed by French rose breeder, Bizot, in 1868. Its origin is unknown, although believed to be the outcome of a cross between a Boursault rose and a Hybrid Perpetual rose. The new rose cultivar was first introduced in Switzerland by the horticulturalist Charles Bonnet, who sold it under his own name in 1868. It was later introduced in Australia by Hazlewood Bros. Pty. Ltd. in before 1921 as 'Zéphirine Drouhin'.

History
'Zephirine Drouhin' was developed by a French rose breeder named Bizot in 1868. It is thought to be the result of a cross between a Boursault rose and a Hybrid Perpetual rose. The rose was most likely named after the wife of a rose enthusiast from Semur-en-Auxois (Côte-d'Or). The new rose cultivar was first introduced in Switzerland by the horticulturalist Charles Bonnet, who sold it under his own name in 1868. It was later introduced in Australia by Hazlewood Bros. Pty. Ltd. in before 1921 as 'Zéphirine Drouhin'. The rose has produced three child plants: 'Emily Rhodes', (Clark),1937), 'Kathleen Harrop' (sport, Dickson II, 1919) and 'Marthe' (sport, Knudsen, before 1912)
