==Pests and diseases==
''Clematis'' species are susceptible to several pests and diseases. Clematis wilt, a stem rot caused by the fungus ''[[Phoma clematidina]]'', causes dramatic wilting and death of whole branches, although many species are resistant to it.<ref>Howells, J., ''Choosing your Clematis'', Garden Art Press, 2003, pp115-116 {{ISBN|1-870673-47-6}}</ref> The species of this genus are also [[alternate host]]s of [[Puccinia recondita f.sp. tritici|''Puccinia recondita'' f.sp.
