Description
Astilbe Red Sentinel is a compact, clump-forming perennial with glossy, divided dark green leaves that emerge tinged deep red. Upright red stems carry dense crimson-red flower spikes in early summer, creating a strong vertical accent above the rounded foliage mound.
Grow it in partial shade in rich clay or loam that stays moist through summer. It accepts acid, neutral, or alkaline soil and also performs beside streams, ponds, and boggy borders where the crown is not permanently submerged. Protect the foliage from hot midday sun and drought.
Divide established clumps in spring. No routine pruning is required, although dry stems can be cut to ground level in late winter. Watch for vine weevil, powdery mildew, and leaf spot.
