Description

Spiraea alba is a mounding, deciduous shrub that grows to a height of 5'. The green leaves are narrow, sometimes lime-green with more sun. They turn golden- yellow in fall. It produces dense, conical, very showy clusters of white flowers in summer.

Cultivation

Native to low-lying prairies and water margins, it is a moisture loving shrub. It can be used in typical garden settings, such as cottage gardens, provided the soil is never allowed to dry out. Spiraea alba is quite shade tolerant, though flower production will be at its best in full sun. Removing spent flowers will encourage production and extend bloom times. A summer bloomer: June to August. Zones 3-6

Propagation

Propagate from seed, or by hardwood cuttings when the plant is dormant in late fall or early spring. Softwood cuttings can be taken in early summer, and rooted.

Additional Notes

Spiraea alba is good summer source for cut flowers. As a member of the rose family, Spirea can be susceptible to the same afflictions, including fungal diseases and aphids.
