Clematis patens is a species of perennial plant in the genus Clematis in the Ranunculaceae family. It is native to Japan (Honshu, Shikoku, and northern Kyushu) and Northeast Asia. It usually grows on the edge of forests. It is also planted for ornamental purposes.[4]

Etymology

The name of the genus Clematis is a derivation of the Ancient Greek word "clématis", which means "climbing". This is a description of the tendency that species show to be climbers.[5] And patens means "opening". In Japan, C. patens is called "kazaguruma", which means pinwheel.[6]

The leaves are pinnate compound leaves consisting of 3–5 leaflets and length of 3–10 cm.[7]
