About this tree

Endless Summer is the original reblooming hydrangea, flowering on both old and new wood for months of color from summer through fall. This rounded shrub reaches 3-5 ft. tall and wide and is hardy across USDA zones 4-9. The big mophead blooms turn blue in acidic soil and pink in alkaline soil, so you can tune the color to your liking. Plant in morning sun with afternoon shade and moist soil for the most prolific show.

Full planting & care

Planting+

Choose a spot with partial sun or partial shade and rich, moist, well drained soil. Dig a hole twice as wide as the root ball and just as deep, set the tree so the top of the root ball is level with the ground, backfill, and water in well. Space about 3 ft. - 5 ft. from other plants.

Watering+

Keep the soil consistently moist, especially through the first two seasons; water deeply 2–3 times a week in summer heat.

Fertilizing+

Feed in early spring with a balanced slow-release fertilizer formulated for trees and shrubs. A second light feeding in early summer supports vigorous growth. Avoid fertilizing late in the season.

Pruning+

Prune in late winter while dormant to remove any dead or crossing branches and to shape. Minimal pruning is needed otherwise.

Frequently asked questions

How do I change the bloom color?+

Acidic soil produces blue blooms and alkaline soil produces pink. Amend with garden sulfur for blue or lime for pink.

Why is it called reblooming?+

Endless Summer flowers on both old and new wood, so it keeps producing blooms all season even if a late frost nips the buds.

How much sun does it need?+

Morning sun with afternoon shade is ideal. Too much hot afternoon sun can wilt the blooms.

What zones is it hardy in?+

It grows reliably across USDA zones 4 through 9.
