Comptonia peregrina (L.) J.M. Coult.

Sweetfern, sweet fern

Sweetfern is literally in a class by itself, being the only member of genus Comptonia. (The genus is named from Henry Compton, bishop of London from 1632-1713.) Sweetfern is native to eastern North America. Although its foliage is fern-like, it is not actually a fern. Ferns don’t flower, and sweetfern does. The common name refers to the odor of its foliage, not its flowers. The odor is stronger when the leaves are crushed.

Plants: Deciduous shrubs up to 5′ (1.5 m) tall. Stems are woody and strong, red-brown to gray.

Leaves: Linear to lanceolate, lustrous, olive to dark green, deeply notched, and 1–6 ⨉ ⅛–1″ (3–15 cm ⨉ 3–30 mm). They are somewhat fernlike in appearance, but on close inspection, the long narrow leaves are not symmetrical like those of ferns.

Flowers: Flowers of both sexes occur on the same plant. Staminate (male) flowers are in clustters at branch tips, up to 1¾″ (5 cm) long. Pistillate (female) flowers are ⅛″ (5 mm) long. Flowers appear from April to May.

Fruits: Pistillate flowers become up to 1¾″ (5 cm) long. Each fruit has four greenish-brown burr-like nutlets.

Habitats: Dry sandy sites, often together with pines.

Edibility: Leaves are edible, added as a flavoring to soups and stews and often removed after cooking, like bay leaves. Nutlets are edible too. See this Forager | Chef article by Alan Bergo.
