Japanese honeysuckle, also known as Lonicera japonica, is a popular ornamental plant with fragrant and delicate flowers that bloom in the summer. Though beautiful, the plant can become invasive and damage native flora. That's why gardeners may want to consider alternatives to Japanese honeysuckle, such as the native trumpet honeysuckle, Lonicera sempervirens, which is less invasive and supports local wildlife. Other substitutes include climbing roses, clematis, and sweet autumn clematis, all of which can provide similar or different looks and fragrances to suit different tastes. In any case, it's always a good idea to research local regulations and consult with experts before planting any new species.
