Japanese Honeysuckle (Lonicera japonica) is an ornamental vine found along the Eastern seacoast, and is considered invasive because it smothers native plants by competing for nutrients, sun and water.

​

It is native to Asia, but in the U.S. it has no natural predators.

​

Flowering in late spring and early summer, it has a sweet scent. And the flowers, seeds and leaves are used in medicines to relieve headaches, arthritis, diabetes, cancer and more.

​

Yet all parts of the plant are poisonous to dogs.
