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 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. It is colloquially called "bush honeysuckle" in the United States, and is considered an invasive species.
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]
