Lespedeza bicolor 'Yakushima'
Lespedeza bicolor can be an invasive pest but this dwarf version from Japan is a non-invasive pixie. Small blue green leaflets in 3's on a many-stemmed 12" tall deciduous bush to twice as wide or a bit more. Cute reddish purple pea-like flowers are perfectly in keeping with the tidy presentation. From a friend on Cape Cod.
