スイカズラ
Even though it is a highly invasive, and destructive plant, this species is often sold by American nurseries as the cultivar 'Hall's Prolific' ("Lonicera japonica" var. "halliana"), and in the UK as the cultivar 'Halliana'. The cultivar is also known as Hall's Japanese honeysuckle. It is an effective groundcover and has strong-smelling flowers. It can be cultivated by seed, cuttings, or layering. In addition, it will spread itself via shoots if given enough space to grow. The variety "L. japonica" var. "repens" has gained the Royal Horticultural Society's Award of Garden Merit.
