Japanese honeysuckle 'Sweet Isabel'

Lonicera japonica 'Sweet Isabel' | Rating: 0 votes | Print / Pdf

With arguably the most delicate-looking fine white blossoms to be found anywhere, lonicera japonica is understandably a highly desired climber amongst gardeners. Known as the Japanese honeysuckle, this semi-evergreen perennial has mid to dark green, ovate leaves, which grow from reddish-brown stems. In early summer, elegant, double-tongued white tubular blossoms that have a strong vanilla fragrance enhance the attractive foliage. These flowers give way to small dark blue berries in autumn. Japanese honeysuckle grows best in moist but well-drained soil in full sun. Highly invasive, it typically needs some pruning to curtail growth. It is a stunning addition to cottage gardens, where walls, trellises and fences require cover.
