Loose, carefree habit lends itself beautifully to mass plantings and use in pollinator-friendly gardens. 

We recommend a minimum of four hours of sun and a maximum of six to keep it from burning and to achieve the strongest stems and the most abundant flowers. In cool climates, position it in a spot that gets morning shade. This helps the plant warm up slowly in spring, which protects its eventual flowers from damage. In hot climates, afternoon shade is beneficial, but some sun is still recommended for the best results.

Cascade hydrangeas form flowers on old wood, so it's best to avoid pruning them, except to remove any dead wood. These hydrangeas cannot be cut back or trimmed at any time of the year without impacting the bloom for either the current season or the next. 

A 2-3" (5-7.6 cm) layer of shredded bark mulch helps shallow-rooted hydrangeas to conserve moisture and keep roots growing vigorously, which ensures the best performance. Fertilize in early spring, after the ground has thawed but before new growth begins, to ensure the best results.
