Of all the clematis we grow (and it’s far too many), this one always stands out as a favourite.  It is probably the most floriferous clematis in the garden and each year it covers a small tool shed with a staggering number of flowers.   The flower stems are longer than many clematis and hold the flowers clear of the foliage.  The colour of the flowers changes with light levels and in the middle of a sunny day appears to be a bleached-out lavender colour.  By the end of the day the colour has become more intense and the bar down the centre of each sepal darker. Like most clematis it prefers cool, rich moist soil in full sun or partial shade.
