About Endless Summer Hydrangea
Endless Summer Hydrangea (Hydrangea macrophylla 'Endless Summer') was the first widely sold bigleaf hydrangea bred to bloom on both old and new wood, meaning that even if late frost or overzealous pruning damages the previous year's stems, the plant still produces flowers on new growth the same season. It grows 3-5 feet tall and wide and produces classic mophead flower clusters whose color shifts with soil pH: blue in acidic soil, pink in more alkaline soil, and often a muddy mauve in Georgia's moderately acidic clay unless amended. Morning sun with afternoon shade is ideal in our climate, since intense afternoon sun causes wilting even with adequate soil moisture. Endless Summer needs consistently moist soil and struggles more than Limelight or Oakleaf Hydrangea during hot, dry stretches, so it's best sited where irrigation is reliable. Because of its extended bloom window and ability to recover from a hard winter, it remains one of the most popular hydrangeas for Lawrenceville shade gardens and foundation plantings that get filtered morning light.

Planting Instructions & Regional Tips
Site Endless Summer Hydrangea where it gets morning sun and afternoon shade; Georgia's intense summer afternoon sun causes excessive wilting even in moist soil. Amend planting soil with compost, and adjust pH with garden sulfur for blue blooms or lime for pink. Water deeply and frequently, especially in summer, since this hydrangea is less drought tolerant than panicle types like Limelight.

Endless Summer Hydrangea FAQs
How do I make Endless Summer Hydrangea blue?
To turn Endless Summer Hydrangea blooms blue, lower the soil pH to around 5.0-5.5 using garden sulfur or an aluminum sulfate soil amendment, since blue color develops only when aluminum is available to the plant in acidic soil. Georgia's naturally acidic clay often produces blue-purple blooms without amendment.
Why is my Endless Summer Hydrangea not blooming?
The most common reasons Endless Summer Hydrangea fails to bloom are late frost damage to old-wood buds, over-pruning in fall or winter, too much shade, or inconsistent watering during bud formation. Because it reblooms on new wood too, most plants still flower some even after a rough winter.
