Inflorescence of Hydrangea serrata

Hydrangea serrata (Thunb.) Ser. var. serrata

The inflorescence of Hydrangea serrata is a corymb ranging from 5 to 15 cm in diameter, consisting of central fertile and peripheral sterile flowers. Its structure and coloration are key ornamental traits that depend on soil nutrient conditions and water availability.

In the reference 149 varieties crop Tea-of-heaven, where this is mentioned in the description.

The inflorescence of Hydrangea serrata has a typical corymbose shape, known as "lacecap." It is structurally divided into two types of flowers: numerous small fertile flowers located in the center, and showy sterile flowers forming a marginal ring around the inflorescence. The diameter of the corymb, which is used as a primary quantitative indicator for cultivar identification, varies from 5–8 cm to 15 cm.

The color of the sterile flowers directly correlates with soil acidity: blue or purple shades appear on acidic substrates, while pink shades occur on neutral and alkaline ones. The size and development of the inflorescences are critically dependent on water availability during the budding period. Furthermore, the type of flower bud formation on the shoots requires caution during pruning, as removing last year's growth can completely eliminate flowering in the current season.
