Best known for its sweet aroma and delectable nectar, Honeysuckle flowers can be found across the Northern Hemisphere and are used for a variety of purposes. Honeysuckles belong to the Lonicera genus, which contains approximately 180 species. 100 of these species are native to China, while about 20 each are believed to belong to North America, India, and Europe. The vast majority of the species in the Lonicera genus are twining climbing vines. Many species can grow as high as 33 feet in height, with leaves that are between 3-8 centimeters in length and 2-5 centimeters in width. Petals vary in color by species and are typically red, pink, yellow, white, or orange. Hummingbirds and butterflies most commonly eat Honeysuckles, though a variety of animals enjoy their fruits and nectars. Japanese Honeysuckle is common in the United States (yellow and white petal colors) despite being invasive to the area. Japanese Honeysuckle (Lonicera japonica) and Honeysuckle (Lonicera caprifolium) are made into extracts for use as a more natural cosmetic preservative.
