Desmodium (Ototropis) callianthum

A seldom-seen scrambling shrub with subtly variegated clover-like foliage (2 or 3 shades of green) and rich pink pea flowers. 

Either grow it among other shrubs so it can scramble about among them, or, if you feel motivated, train it against a wall. Either way it makes a very welcome splash of colour in late summer and autumn
