Description

Sweet Fern (Comptonia peregrine) is an upright, deciduous shrub (typically growing 2-4 feet tall) which features simple, narrow, lustrous, pinnatifid, deeply notched, olive to dark green leaves (to 4 inches long). Insignificant, yellowish green flowers appear in spring and give way to greenish brown, burr-like nutlets. Occurs in poor, sandy or gravelly, infertile soils, such as along roadsides. The root system can develop clonal offsets from underground runners. Clonal colonies of plants are common from such offsets.

Habitats include upland sand prairies, sandy shrub prairies, and sandy upland savannas. Sweet Fern benefits from occasional wildfires as this reduces competition from taller shrubs and trees. The seeds can lie dormant in the soil for several decades while waiting for such wildfires to occur.

Easily grown in average, medium, well-drained soil in full sun to part shade. Adaptable plant that tolerates wet conditions and wind (including sheltered seashore areas), drought and a wide range of soils (prefers sandy, acidic loams, but tolerates poor soils). Once established it can spread rapidly to form colonies.

A good shrub for areas with poor soils.
