Steeplebush 3 Gallon
Spiraea tomentosa — Steeplebush
Native shrub · Zones 3–7 · Full sun to part shade · Wet to average soils
A quietly striking native shrub of meadows, bogs, and stream edges, Steeplebush earns its name from the tall, narrow spires of deep rose-pink flowers that bloom in mid-to-late summer — right when many other flowering shrubs have gone quiet. The densely woolly, rust-colored undersides of its leaves are the other giveaway, giving the plant a warm, textured look even when not in bloom.
Why grow it: Steeplebush is a workhorse for rain gardens, wet meadow plantings, and naturalized edges where few shrubs want to settle. It spreads gradually by root suckers to form colonies that stabilize soil and provide season-long structure. The long bloom period — July through September — makes it a late-summer pollinator magnet, particularly for native bees and butterflies.

Design notes: Use in mass plantings along pond edges, in rain gardens, or as a naturalized hedge. Pairs beautifully with Lobelia cardinalis, Eupatorium species, and native grasses. Fall foliage turns warm orange-red, extending seasonal interest well into autumn.
Spiraea tomentosa is native to eastern North America and a smart choice for ecological landscapes prioritizing native plant communities and pollinator support.
