Endless Summer® The Original Hydrangea (Hydrangea macrophylla ‘Bailmer’)

Endless Summer® The Original Hydrangea (Hydrangea macrophylla ‘Bailmer’) is one of the most popular reblooming hydrangeas, known for its ability to flower on both old and new wood. This unique characteristic allows it to produce blooms throughout the growing season, even after harsh winters, making it a reliable choice for Canadian gardeners seeking consistent colour.

The large, rounded mophead flowers can appear in shades of blue or pink depending on soil pH, adding versatility and interest to garden design. In acidic soils, blooms lean toward blue tones, while alkaline soils produce pink flowers. This adaptability makes it an engaging and customizable feature in landscapes. The lush green foliage provides a full, rounded shrub that works beautifully in borders, foundation plantings, and container gardens.

In Alberta, Endless Summer® performs best in a protected location with morning sun and afternoon shade. It requires consistent moisture and benefits from mulching to help regulate soil temperature and retain water. While hardy, it may need winter protection in colder zones to ensure reliable blooming.

This hydrangea is ideal for gardeners looking for a long-blooming, showy shrub with season-long colour and strong landscape impact.
