Honeysuckle \Hon"ey*suc`kle\, n. [Cf. AS. hunis[=u]ge privet. See Honey, and Suck.] (Bot.) One of several species of flowering plants, much admired for their beauty, and some for their fragrance.
Note: The honeysuckles are properly species of the genus Lonicera; as, Lonicera Caprifolium, and Lonicera Japonica, the commonly cultivated fragrant kinds; Lonicera Periclymenum, the fragrant woodbine of England; Lonicera grata, the American woodbine, and Lonicera sempervirens, the red-flowered trumpet honeysuckle. The European fly honeysuckle is Lonicera Xylosteum; the American, Lonicera ciliata. The American Pinxter flower ( Azalea nudiflora) is often called honeysuckle, or false honeysuckle. The name Australian honeysuckle is applied to one or more trees of the genus Banksia. See French honeysuckle, under French.

Lonicera caprifolium, the Italian woodbine, perfoliate honeysuckle, goat-leaf honeysuckle, Italian honeysuckle, or perfoliate woodbine, is a species of perennial flowering plants in the genus Lonicera of the Caprifoliaceae family. It is native to parts of Europe, and naturalised in South East Britain and northeastern North America. It can readily be distinguished from Europe's most common species, Lonicera periclymenum, by its topmost leaves which are perfoliate as the Latin name suggests (that is, the stem appears to grow through the centre of the leaf). It is a vigorous, deciduous climber growing up to 8 metres. It bears masses of very fragrant, cream-coloured flowers, tinged with pink, appearing in midsummer.
