Lonicera morrowii, the Morrow's honeysuckle, [1] [2] is a deciduous honeysuckle in the family Caprifoliaceae, native to Japan, Korea, and Northeast China. It is colloquially called "bush honeysuckle" in the United States, and is considered an invasive species.

Contents

Description

It is a shrub, reaching a height of 2–2.5 m, with oblong leaves 4–6 cm long. It leafs out quite early in the spring, and in North America is commonly the first deciduous shrub with foliage in March. The flowers are white to pale yellow, and the fruit is a dark red berry 7–8 mm diameter containing numerous seeds. The berries, while eaten frequently by birds, are considered poisonous to humans.

Taxonomy

In cultivation, Lonicera morrowii has hybridized with other shrubby species of Lonicera. Crossed with L. tatarica , it forms the invasive hybrid L. × bella. [3] It can also hybridize with L. ruprechtiana . [4]

As an invasive species

Morrow's honeysuckle is confirmed as a highly invasive species in the northeastern United States. [5] [6] Morrow's honeysuckle thrives at the edges of forests, roads, or other natural or man-made barriers, but is not limited to them, and is found in both mature and disturbed forests. [7] In some areas, Morrow's honeysuckle is the dominant plant species, especially in areas of disturbed ecological succession. It is suspected that Lonicera morrowii is allelopathic, and may capitalize on disturbed ecological succession by establishing itself and then preventing the growth of plants underneath it. [7] With a sufficiently established thicket of honeysuckle, even other shade-tolerant, invasive species, such as Fortune's spindle have difficulty growing underneath it, whether due to its suspected allelopathic activity or through soil depletion. [8]

Effects on flora and fauna

Due to its early leafing, Morrow's honeysuckle is particularly harmful to spring ephemerals, flowers that evolved to bloom briefly in the spring before other plants leafed out. [8]

Many cedar waxwings' wax spots in the eastern United States have taken on an unusual orange hue in the last 35 years, a phenomenon that has been attributed to Lonicera morrowii. [9] The chemical involved in this color change is rhodoxanthin, a red dye found in the berries of Morrow's honeysuckle.

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.

Lonicera × bella, known as Bell's honeysuckle and showy fly honeysuckle, is a hybrid species of flowering plant in the family Caprifoliaceae. It was first described by Hermann Zabel in 1889. Zabel reported that he grew it in cultivation from seeds obtained from a plant of Lonicera morrowii, but that its appearance suggested the influence of L. tatarica. It has escaped from cultivation and become an aggressive invasive species in central and eastern parts of the United States.
