Astilbe 'Red Sentinel' - 2026

Astilbe 'Red Sentinel' is a striking perennial known for its vivid crimson-red flower plumes that rise prominently above rich green foliage. Blooming from mid to late summer, its tall, upright flowers create a bold vertical accent in shaded borders, woodland gardens, or near pond edges. The vibrant red blooms provide a dramatic contrast to lighter-coloured plants and offer long-lasting visual interest throughout the season.

This cultivar thrives in moist, humus-rich soils and prefers partial to full shade, although it can tolerate some morning sun if the soil remains consistently damp. Low-maintenance and reliable, Astilbe 'Red Sentinel' benefits from mulching to retain moisture and cutting back old stems after flowering. Its nectar-rich flowers are highly attractive to pollinators, enhancing both the ornamental and ecological value of the garden.
