Lindera benzoin — northern spicebush

Copyright: various copyright holders. To reuse an image, please click it to see who you will need to contact.

Facts

Northern spicebush is named for its leaves, which are aromatic when crushed. A denizen of bottomlands and other moist places, this tall shrub produces masses of small green-yellow flowers in spring, before the leaves appear. Male and female flowers are borne on separate plants. Caterpillars of the spicebush swallowtail butterfly (Papilio troilus) use this species for food. The green caterpillars have large, black, fake "eye" markings that scare away predators. With sweetly aromatic foliage that turns yellow in the fall, this plant is a good choice for shady, moist or wet places in the garden.
