The genus Clematis contains ~300 species native to many regions of the globe. While cultivated since the 1500s, it wasn’t until 1835 that the first hybrids, C. ‘Eriostemon’ and ‘Henderson’, were reported. Currently there are many interspecific hybrid cultivars and numerous mutations from numerous species on the market. While clematis are traditionally grown as vines, there are nonvining species which can be used to diversify the crop. Traits of interest to flower breeders for crop transformation include: plant architecture, flowering (color, size, timing), attractive seed heads, foliage (phyllotaxy, coloration, or other morphological traits), environmental adaptation to stressful conditions (cold tolerance, heat tolerance, drought stress, etc.)
