Sweet Fern

Comptonia peregrina (komp-TOH-nee-uh per-uh-GREE-nuh)

Family: Myricaceae Native Shrub (3-15 ft)

This plant is a low maintenance shrub in the Myricaceae family. This native to eastern North America has aromatic foliage that resembles ferns, hence the common name of sweet fern. It is often found along roadsides and is capable of fixing its own nitrogen. It works well in rain gardens or be allowed to naturalize. Once established, it can spread rapidly to form colonies. This beautiful plant has a delicate look that will give that exotic, lush feel to your garden and enhance its beauty with its luxurious green leaves. A plant that tolerates many conditions including drought, wet sites, and wind. It can even grow in sheltered seaside locations. Prefers sandy acidic loams, well-drained, in full sun to part. It does not transplant well so choose a location carefully. This would make a good choice for stabilizing slopes or embankments. This plant naturalizes, wet sites, deciduous, low maintenance and has fragrant leaves. Insects, Diseases, and Other Plant Problems: No significant insect or disease problems.
