$0.00

DESCRIPTION
Astilbe japonica ‘Red Sentinel’ produces upright plumes of rich crimson-red flowers that rise above mounds of glossy, dark green foliage in early summer. The feathery blossoms hold their color well as they open, while the finely divided leaves provide a polished backdrop through the growing season. Developed in Europe during the twentieth century as part of the japonica breeding group, this cultivar has become widely valued for dependable flowering and refined garden presence.

In the landscape, ‘Red Sentinel’ suits borders, woodland gardens, and mixed perennial beds where its bold flower plumes create seasonal highlights. It also performs well in mass plantings and as a fresh or dried cut flower, adding color and structure to designs.
