Steeplebush (Spiraea tomentosa) is a native shrub of wet habitats, generally 1 to 2 m tall, with an upright form, often forming small colonies at the edge of marshes or natural ditches. Its leaves are oval, slightly fuzzy on the underside, medium green in summer and turning yellow in fall. The highly ornamental flowering occurs in summer as long conical spikes of small bright pink flowers. The species grows in full sun in bogs, wet meadows and poorly drained banks, tolerating acidic and constantly moist soils.

Ecological roles
Steeplebush produces an abundance of nectar highly valued by bees, bumblebees and butterflies in midsummer. Its dense colonies also provide shelter for beneficial insects and certain small birds of riparian habitats. Its ability to establish in wet and unstable soils makes it useful for the light stabilization of wetland environments.

 

Steeplebush seeds require scarification and cold stratification to ensure germination. See the cultivation notes below for more details.

Growing Notes | Seeds - Steeplebush

Steeplebush grows in full sun in wet, acidic and poorly drained soils, typical of riparian and boggy habitats.

The seeds require a 60-day cold and moist stratification. To do this, simply mix the seeds with a moist substrate (such as vermiculite), and place the mixture in a hermetic Ziploc-style bag in the refrigerator for about 60 days. This step may be carried out naturally by outdoor sowing in fall.

Then sow on the soil surface, without covering, as the seeds need light to germinate. Maintain constant moisture. Germination generally occurs after 30 to 90 days.

Growth is slow at first. Once established, the plant requires no maintenance, but must be installed in soil that remains consistently moist.
