The Original Endless Summer Blue Hydrangea is the first hydrangea that blooms both on the previous year's branches as well as the new season's growth. This shrub has beautiful blue flowers spring through summer. The colour of blooms depend on soil pH, which can be amended using an acid fertilizer in the early spring. The compact size of the shrub of 4 feet tall and wide will fit almost any landscape. Makes a superior accent or specimen plant. These also make great cut flowers for arrangements.
