Japanese honeysuckle (Lonicera japonica) is a vigorous, twining perennial vine native to eastern Asia, known for its fragrant white flowers that gradually turn yellow and its dark berries that appear later in the season. It is attractive to bees, butterflies, and hummingbirds, but its rapid growth allows it to overwhelm other plants and native vegetation. Japanese honeysuckle is considered invasive in many parts of the United States, including California, where it can be difficult to control once established.
It is generally considered non-toxic to dogs and cats, although eating large quantities of the leaves, stems, or berries can cause mild stomach upset, including vomiting or diarrhea. Its sweetly scented flowers are attractive to bees and other pollinators, but pets should still be discouraged from chewing on the plant.
