Botanical Nomenclature and Synonyms

The scientific name of Common Honeysuckle is Lonicera periclymenum, first described by Linnaeus in 1753. It has several synonyms, including Lonicera x altaica and Lonicera x morrowii, reflecting historical taxonomic classifications. Common names such as Honeysuckle, Elderberry, and Woodbine are widely used, though some regional and historical names may vary.

Morphological Characteristics

Common Honeysuckle is a deciduous shrub with a spreading growth habit. It has a fibrous root system that anchors it firmly. The stems are twining and often climb by grasping branches. Leaves are opposite, ovate, and have serrated edges. The inflorescence consists of pairs of flowers on short pedicels. Flowers are fragrant, tubular, and typically yellow or orange. The fruit is a red, fleshy berry containing small, black seeds.

Diagnostic Identification Features

Lonicera periclymenum can be distinguished by its opposite, oval leaves with serrated edges, red-orange tubular flowers, and four-lobed, yellowish-brown berries. It differs from L. japonica by its smaller, more oval leaves and distinct flower color. The stems are usually hairy, and the plant typically grows in open woodlands or along roadsides.

Natural Habitat and Geographic Distribution

Common Honeysuckle is native to Europe and western Asia. It thrives in temperate climates with mild winters and warm summers. It prefers well-drained, loamy soils and is typically found at low to moderate altitudes, often near woodlands or stream sides.

Phenology and Growth Cycle

Common Honeysuckle blooms from late spring to early summer, typically May to July. Seed formation occurs in late summer to early autumn, around August to September. For identification purposes, harvest timing is critical between late summer and early autumn when the berries are ripe and most identifiable.

Phylogenetic Relationships

Lonicera periclymenum belongs to the genus Lonicera within the family Caprifoliaceae. It is closely related to species like Lonicera japonica and Lonicera morrowii. These species share similar morphological and genetic traits, such as opposite leaves and tubular flowers, which are characteristic of the Caprifoliaceae family.
