Sweetfern
Comptonia peregrina
Sweetfern, a low shrub of Atlantic North America, is striking both due to the fern-like shape of its lobed leaves and their
strong, pleasant scent, which is typical for all members of bayberry family, where the plant belongs. Sweetfern is a non-legume
nitrogen fixer, growing mainly on dry, acidic, sandy or rocky sites and improving the soil there. It beautifies and mends
difficult eroded slopes where no other woody plant would dare to grow. Sweetfern flowers at the start of May, before it produces
the leaves. The male (staminate) flowers are at tips of branches in dangling catkins up to 2” long, while the fruiting flowers
form tiny bright red clusters, which develop into fruit clusters in summer. The leaves provide food for several butterfly
and moth caterpillars including gray hairstreak. This attractive and useful compact shrub is sometimes available at nurseries.
