Steeplebush (Spiraea tomentosa) brings bold midsummer color with narrow, steeple-like spikes packed with tiny pink flowers. You can use it to add seasonal height and a natural, meadowy look while supporting pollinators and other garden visitors.
Expect an upright, multi-stemmed shrub that typically matures around 36-72 inches tall. It can spread by suckers, so you can let it form a broader patch or keep it more contained with routine edging and selective removal of new shoots.
Plant it where the soil stays evenly moist; it is especially well-suited to low spots, pond edges, rain-garden style areas, and other sites that stay damp. Full sun gives the densest growth and best flowering, but it also performs in part shade, especially where afternoons are hot.
Simple pruning keeps it looking fresh. Because it flowers on new growth, you can cut back in late winter or early spring before new growth begins, removing older stems and shaping as needed. Deadheading can extend the display, but leaving some spent blooms can provide seed for birds later in the season.
Pair steeplebush with other moisture-loving natives and grasses for a layered look, and give it room to show off its long summer bloom.
