Smooth hydrangeas (Hydrangea arborescens) are some of the most dependable, easygoing flowering shrubs you can grow in Chicagoland gardens. If you\u2019ve ever admired massive white blooms that show up every summer without a ton of fuss, chances are you were looking at a smooth hydrangea. Native to the eastern United States and exceptionally cold-hardy, these shrubs are a go-to choice for Zone 5 gardeners who want reliable blooms year after year.<\/span><\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ _builder_version=”4.27.4″ _module_preset=”default” custom_padding=”||26px|||” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n Smooth hydrangeas have earned their reputation as workhorse shrubs, and for good reason.<\/span><\/p>\n For Zone 5 gardeners, this reliability is huge.
