A very vigorous climbing plant, it makes a good dense ground cover plant where it has the space to run over the ground but it will swamp smaller plants. The sub-species L. japonica repens is especially used for this purpose on the continent. The cultivar 'Halliana' has also been recommended. This cultivar should be clipped back severely in the spring if it gets untidy, it responds well to such conditions. Plants should be spaced about 1 metre apart each way. The plant is said to be insecticidal. The stems have been used in making baskets.
