Non-Native Bush Honeysuckles

Lonicera spp.

In Ontario 3 species of invasive honeysuckles can be commonly found. Each of these species produces a slightly different coloured flower, ranging from red, yellow, pink to white. Towards the end of the summer these flowers will give way to two red berries which are fused together. Another key ID feature is that all invasive honeysuckle shrubs in Ontario have hollow stems, while native honeysuckles tend to have full twigs lacking a hollow pith.

Once established, these invasive shrubs can crowd out native understory vegetation. They are capable of producing high quantities of seed and therefore removing this shrub before populations increase is advised. Many land managers report high levels of success by removing this shrub manually with a removal tool (e.g. Extractigator, Weed Wrench, etc.).
