Invincibelle Sublime hydrangea (H. arborescens) ushers in a new day for full-sized smooth hydrangeas, with cloud-like mophead flowers floating above the plant on super-sturdy stems. Each floret of the big, fluffy blooms is a deeply saturated tourmaline-green that looks refreshing and intriguing in the garden all summer long. Very dark green foliage sets off the lively green of the blooms. Makes a fantastic cut flower, both fresh and dried, if you can bring yourself to remove them from the fabulous plant.Continuous Bloom or RebloomerLong BloomingDeadheading Not NecessaryNative to North America

We recommend a minimum of six hours of sun for smooth hydrangeas like Invincibelle Sublime for the strongest stems and the most abundant flowers. In hot climates, afternoon shade is beneficial, but some sun is still recommended for the best results.
Prune Invincibelle hydrangeas in early spring, just as the new growth begins to emerge on the stems. Remove any dead wood and cut the entire plant back by about one-third its total height. This helps to preserve the strong woody base while also encouraging new growth for the best blooming.
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.Fun Facts:
