The paper studies the water regime of panicle hydrangea and 16 varieties of this species introduced into South-Ural Botanical Garden-Institute of the Ufa Federal Research Centre of Russian Academy of Sciences. The purpose of the work is a comparative assessment of hydrangea varieties resistance to drought and the identification of the most promising taxa suitable for cultivation in the Bashkir Cis-Urals. The study assesses the total moisture content, water retention capacity and the content of mobile moisture in hydrangea leaves for the growing season. It has been found that the total moisture content (water content in the tissues) of panicle hydrangea leaves and its varieties is quite high and ranges from 72 to 82%. Certain varieties (Bobo, Levana, Phantom, PrimWhite, Silver Dollar, Sandy Fraise, Unique) have an ability to increase water retention during flowering. The following varieties are most adapted to dry periods under growing conditions in the forest-steppe zone of the Bashkir Urals: Kyushu, Prim White and Wims Red, the least drought-resistant ones are Tardiva, Sandy Fraise and Praecox; the other 10 varieties are classified as hydrangeas with medium drought resistance. H. paniculata has average values for all parameters of the water regime and their value does not depend on the phenophase.
