Dogwoods, hydrangeas, and allies comprises a diverse order of flowering plants distinguished by their woody structure often consisting of trees and shrubs. A defining trait is their small, generally inconspicuous flowers, which gather in dense clusters, influencing pollination dynamics. The habitat's climate and soil primarily shape dogwoods, hydrangeas, and allies's distribution, contributing to their resilience and adaptive features. These species display a significant variation in leaf characteristics, which serve as a practical guide for species identification.
