A new and distinct cultivar of Hydrangea macrophylla (Thunb.) named ‘BCHY-11.033’ originated as a controlled cross between varieties. The variety ‘BCHY-11.033’ has attractive inflorescences with relatively large sepalous florets, attractive, nonuniform sepal pigmentation and good commercial characteristics. Many non-sepalous florets in the center of the inforescence make the new variety look similar to a lace-cap variety.
