This semi-double flowering cultivar has later summer flowers. The flower opens lilac-blue, maturing to a pale lilac-blue and has contrasting purple-red anthers early summer to late summer.. Its multi-flowering habit is unique for a summer flowering, large-flowered clematis, as its blooms are produced in great abundance. Many blooms change colour as they mature, giving an appearance of a multi-coloured flowering clematis, an added interest.
