Clematis lanuginosa is a flowering vine of the genus Clematis. It grows among bushes in somewhat stony soil on mountain slopes and in river beds at 100-400 m elevation. The flowers of the plant are flat, from almost white to light blue in colour.
Clematis lanuginosa is endemic to Zhejiang province in eastern China and was first discovered near Ningbo by the plant hunter Robert Fortune in 1850 who sent plants back to England. It was lost to cultivation at about the time of the first world war and thought to be extinct but was rediscovered growing in the same area in 2008. It is a twice-bearing clematis that blooms once in spring and again in summer. It is best known as a parent species for many of the large-flowered varieties of Clematis.
