Data are presented on changes in the total water content in leaf tissues and the level of real water deficiency in 7 genotypes of garden roses ( Rosa gallica L., R. odorata var. gigantea × R. multiflora , R. hugonis Hemsl., R. chinensis var. minima (Sims) Voss., R. bracteata J.C. Wendl., and R. foetida var. persiana (Lem.) Rehder) and cv. ‘Borisfen’ during the summer seasons of 2022–2023 on the Southern Coast of Crimea.
