Out with the same old, same old, and in with this gorgeous native hydrangea! Invincibelle Sublime™ has so many lovely traits, it’s hard to pick a favorite. To start, its flowers are striking all season long. Each set of sepals is lime green with bright pink fertile florets at the center, inviting you to lean in and enjoy the details of your garden. Its foliage is a rich, healthy forest green color, really setting off the light green flowers. The unsung heroes of this show are its incredibly sturdy stems, able to hold up large blooms all through the summer and fall, even through the winter. We’ve seen it thrive in full sun even in Florida, so you can grow it in your garden with confidence.

Why grow Invincibelle Sublime™ smooth hydrangea?

  • It’s native to North America
  • Makes a unique, long-lasting cut flower
  • Very tough – it tolerates extremes in cold and heat very well


Light: It depends on the climate you live in. For gardens at the cooler end of their hardiness range, they will thrive in full sun. For gardens at the warmer end of the range, it benefits from placement in afternoon shade.

Soil: Prefers moist soil that drains easily. Any period of extended sogginess will not be tolerated. Soil pH does not affect flower color.

Water: Average water needs.

Fertilizing: Nothing special required. If desired, you may apply a granular fertilizer formulated for flowering woody plants in late winter/early spring when the soil is workable.

Pruning: Pruning is recommended in early spring. When the buds begin to swell noticeably, cut the whole plant back by one third. Make cuts just about 1/4 of an inch above a bud. Dead or damaged wood can be removed at any time, just cut back to a set of leaves!

Other: It can be used as a cut flower! For its longest vase life, cut vertically up the stem about 2 inches. This will help it absorb more water.
