Hydrangea is one of the most important ornamental plants that is widely used as a garden tree, potted plant and cut flower. The original species used for breeding of hydrangea cultivars are Hydrangea macrophylla, H. serrata and H. serrata var. yesoensis, which are native to Japan. H. macrophylla inhabits in coastal areas directly affected by sea breeze and splash. Thus, it has a highly salinity tolerance. Salinity tolerance is an important horticultural trait for planting in coastal areas as well as roadsides using a salt-derived antifreeze. However, studies on salinity tolerance in wild Hydrangea species remains inadequate. In this report, meteorological information of native habitats and morphological traits of salinity tolerant H. macrophylla were compared with those of H. serrata and H. serrata var. yesoensis.
