Astilbe x arendsii
perennialZones 4–8deer resistantFeathery plume-like flower spikes in pink, red, white, or purple above fern-like foliage. One of the best perennials for shade and moist conditions.
Remove dried flower plumes from last year if they were left for winter interest.
Divide every 3-4 years to maintain bloom vigor. Replant divisions with crowns at soil level.
Astilbe suffers in dry conditions. Water regularly -- brown, crispy leaf edges mean it needs more water.
Dried flower plumes turn coppery-brown and provide winter texture. Leave standing.
