Winter honeysuckle

Lonicera fragrantissima is a species of flowering plant in the honeysuckle family Caprifoliaceae, known by the common names winter-flowering honeysuckle, fragrant honeysuckle, kiss-me-at-the-gate, and sweet breath of spring. It is native to China and has been an introduced species to other parts of the world. It was brought to the attention of western gardeners by Scottish plant hunter Robert Fortune, who was plant hunting in China for the Royal Horticultural Society. Fortune introduced Lonicera fragrantissima to England in 1845, and a few years later it was introduced to the United States. In 1853 the editor of American gardening magazine The Horticulturist wrote that the previous year he had been sent a specimen from a plant that had been flowering in the gardens of Hatfield House, the Marquess of Salisbury's stately home in Hertfordshire. The first mention of a specimen for commercial sale in an American plant catalogue is in 1860.

The honeysuckle is used as an ornamental plant for its fragrant flowers. In some parts of the world, where conditions are right, when it moves out of cultivation and takes hold in the wild, it can become an invasive weed.
