Enjoy Hydrangea macrophylla 'Let's Dance(R) Blue Jangles(R)' for big, full flower heads and a tidy, compact habit that fits small gardens and containers. You will see the classic bigleaf hydrangea look, with bloom color that can shift with soil conditions, often trending bluer in more acidic soil and pinker in more alkaline soil. At maturity it stays about 12-24 inches tall and typically fills out to roughly 24-36 inches wide, making it easy to tuck into borders, entry plantings, or patio pots.
Give your plant part shade for best performance, especially afternoon shade in warmer climates. It can take more sun when the soil is kept consistently moist. Plant in rich, well-drained soil and water deeply during dry spells; a mulch layer helps keep roots cool and evenly moist. This is a woody shrub, so avoid letting it dry out completely, particularly in containers.
Pruning is usually minimal. If you need to shape it, prune right after the main flush of flowers, and remove only dead or winter-damaged stems in late winter or early spring. Many reblooming types can set buds on both older and newer wood, so heavy pruning can reduce flowers.
In colder regions, site it in a sheltered spot and protect the root zone with mulch to help buds and stems through winter. Pair it with shade-tolerant perennials and broadleaf evergreens for a layered, cottage-garden look.
