Taxonomy

Spicebush (Lindera benzoin) was originally described by Carl Von Linnaeus as Laurus benzoin in Species Plantarum (1753). The genus name was later changed in 1851 to the current name, Lindera benzoin. A member of the Laurel Family (Lauraceae), there are three forms known — ‘Rubra’ and ‘Xanthocarpa’ (NC State Extension) and ‘Green Gold’ (Wikipedia).

Synonyms

  • Benzoin aestivale
  • Benzoin aestivale var. pubescens
  • Lindera benzoin var. pubescens

Meaning the Scientific and Common Names

Scientific Name

The genus name, Lindera, is named for Johann Linder, a Swedish botanist. The species name, benzoin, is Arabic for aromatic gum (Missouri Botanical Garden), presumably from the scent that the shrub gives out.

Common Name and Alternative Names

The common name derives from the scent of the shrub. When the bark is bruised or if you are in a large group of them, they give off a spicy scent. Other names, such as northern spicebush and wild allspice, follow a similar idea. Another name is Benjamin Bush, possibly coming from the species name.
