Cultivation
Hydrangea serrata (Thunb.) Ser. var. serrata
Mountain hydrangea is well-adapted to containers due to its naturally compact habit, sturdy stems, and high sensitivity of inflorescence color to substrate chemistry, which is easily managed in a confined volume.
In the reference 65 varieties crop Tea-of-heaven, where this is mentioned in the description.
The species is characterized by its tendency to form a dense shrub 1–1.5 m in height with upright branches, eliminating the need for support. Its high resilience to environmental fluctuations makes mountain hydrangea more predictable when kept on open terraces and balconies compared to bigleaf hydrangea.
Container cultivation allows for precise control of substrate pH to manage inflorescence coloration. Successful culture requires loose, fertile mixes with the addition of peat and pine needles, as well as the use of moisture-retaining components such as perlite, due to the species' high sensitivity to drying out.
Pruning for container-grown plants is limited to the sanitary removal of crossing shoots after flowering. Despite the high winter hardiness of breeding varieties down to -30°C, the ability to move the container to a sheltered location is necessary to prevent critical freezing of the root system in the pot.
