Hydrangea Endless Summer

Hydrangea Endless Summer® is a revolutionary reblooming hydrangea that delivers large, mophead blooms not just once, but throughout the entire growing season. Blooming on both old and new wood, Endless Summer® ensures a continuous display of vivid pink or rich blue flowers, depending on soil pH. With lush green foliage and strong, upright stems, this cold-hardy, deciduous shrub provides season-long color and structure to borders, foundation plantings, and containers. A true garden favorite, it’s ideal for those who want a long-blooming, low-maintenance shrub with reliable performance and classic charm.

Growth Rate and Mature Size

Growth Rate: Moderate growth rate with blooms starting early in the season and repeating into fall. Flowering begins the first year and improves with maturity and proper pruning.

Mature Size: Reaches 3–5 feet tall and 3–5 feet wide. Forms a rounded, bushy shape that remains tidy and compact—perfect for mixed beds, shaded walkways, or as a color-rich backdrop.

Watering and Sunlight

Watering: Requires consistent moisture, especially during bloom time. Water deeply 1–2 times per week; more during extreme heat. Mulch helps retain soil moisture and reduce stress. Avoid letting soil dry out completely.

Sunlight: Prefers partial sun to dappled shade. Morning sun with afternoon shade is ideal, especially in warmer climates. Too much direct sun can cause leaf scorch, while too much shade can reduce flower production.
