Significance

• This shrub blooms on both the previous and current year's growth, providing blooms much longer than other hydrangea cultivars.
  
  As a result, the Endless Hydrangea shrub blooms May through June and October through November. Other cultivars only bloom May through June.
  
  

Theories/Speculation

• To get blue blooms on the hydrangea shrub, plant it in acidic soil. To get pink blooms, plant it in alkaline soil. Garden centers sell ingredients to change the alkaline and acidic levels of soil.
  
  

Warning

• Endless Summer hydrangea prefers partial shade, though will not produce as many blooms if planted in full shade. Other reasons for the shrub not blooming include frost damage. To prevent this, cover the shrub with a bed sheet prior to a frost. In addition, add 2 to 3 inches of mulch around the base of hydrangea prior to winter.
