Behavior

Japanese honeysuckle is a vigorous, semi-evergreen vine known for its incredible ability to climb and blanket surrounding vegetation. It spreads using both underground rhizomes and long surface runners that take root at the nodes. In many regions, it is considered a highly invasive species because its dense growth can shade out native ground cover and even girdle small trees, eventually killing them through 'strangulation.'

Despite its aggressive growth, it is a significant source of nectar for local wildlife. The flowers are famously fragrant, releasing a heavy, sweet scent that intensifies at dusk to attract pollinators. While humans often enjoy the nostalgic scent of the 'honeysuckle season,' ecologists monitor it closely due to its tendency to create monocultures that reduce biodiversity in backyard and forest ecosystems.

Camera Tips

To capture the best action on Japanese honeysuckle, you should treat the plant as a 'station' for pollinators. Mount your camera on a tripod or a fence post about 3 to 4 feet off the ground, focusing on a dense cluster of flowers that are just beginning to open. Because the plant's scent is most potent at dusk, this is the perfect opportunity to use a camera with high-speed infrared sensors to capture the rapid wingbeats of Sphinx moths, often mistaken for hummingbirds as they hover near the blooms at night.

During the day, set your camera to a fast shutter speed or high-sensitivity motion trigger. This will help you catch the rapid movements of Ruby-throated Hummingbirds and various bumblebee species that frequent the nectar-rich tubes. If your camera supports it, a 4K video setting is ideal for documenting the intricate way insects navigate the long floral tubes to reach the nectar at the base.

Since Japanese honeysuckle is an invasive vine that can grow several feet in a single season, it is also a fantastic subject for long-term time-lapse photography. Set your camera to take one photo every 6 hours from early spring through mid-summer. When played back, you will see the dramatic 'strangling' behavior as the vines twine counter-clockwise around supports and literally leap across open spaces to find new territory. Just be sure to prune any leaves that grow directly in front of the lens, as the wind will move them and trigger thousands of empty 'false' videos.

Similar Species

Species that look similar or are commonly confused with Japanese honeysuckle.

Trumpet Honeysuckle

Native to North America with bright red/orange scentless flowers and leaves that are fused together at the base of the flower clusters.

Amur Honeysuckle

An invasive shrub rather than a vine; it grows upright and produces red berries instead of black.

Chinese Privet

Another fragrant invasive shrub with small white flowers, but it has woody upright branches and much smaller, stiff leaves.

Frequently Asked Questions

The fragrance of Japanese honeysuckle peaks between dusk and dawn (approximately 6 PM to 6 AM) to attract nocturnal pollinators like hawk moths and sphinx moths.

You rarely need to do anything to attract them; the plant's heavy scent and high nectar volume naturally draw in hummingbirds, bees, and moths. Simply ensure the plant has enough sunlight to produce a high volume of blooms.

While hummingbirds drink the nectar from the flowers, many songbirds like Purple Finches and Goldfinches eat the small, black berries that appear in the fall and winter.

Yes, they are extremely common in suburbs, often found growing along chain-link fences, climbing telephone poles, or creeping out of wooded edge lots into manicured lawns.

Native honeysuckle (like Trumpet Honeysuckle) usually has red or coral tubular flowers and 'fused' leaves that the stem appears to grow through, whereas Japanese honeysuckle has white/yellow flowers and distinct, separate oval leaves.
