Remontancy — Hydrangea serrata

Hydrangea serrata (Thunb.) Ser. var. serrata

Remontancy in Hydrangea serrata refers to the plant's ability to form flower buds and bloom on both previous year's shoots and current season's growth.

In the reference 5 varieties crop Tea-of-heaven, where this is mentioned in the description.

For mountain hydrangea, this trait is a breeding advantage that allows the plant to bloom even if old wood is damaged by winter frosts or late spring frosts. Unlike species forms that set buds exclusively on last year's shoots, remontant cultivars are capable of producing inflorescences on young growth of the current year.

In breeding practice, remontancy is considered a qualitative characteristic evaluated by a cultivar's ability to form flower buds within a single season. In scientific research, this trait is defined through the concept of high flowering frequency of vegetative cuttings and the study of inflorescence development architecture, although no unified quantitative scale for it has been established.
