Clematis sibirica

Clematis sibirica


Earlier the species was considered as a member of the genus Knyazhiki and was called the Siberian prince (Atragene sibirica). Today the genus Atragene is abolished and merged with the genus Clematis, and therefore we speak about Clematis sibirica from the section Atragene according to the classification of M. Tamura.

Biology and ecology

Siberian clematis rarely grows deep in forests, but it is not found in open areas either. Most often it can be found at edges, in thickets along riverbanks or on rocky slopes covered with sparse trees and shrubs. There it has enough light on one side and climbing supports on the other.

Clematis sibirica blooms twice: the first time very abundantly on the shoots of the last year in May, the second time – with single flowers on the ends of the shoots of the current year in August-September. The fruits of the first flowering ripen in the fall.


Clematis Siberian is rarely found in culture and therefore there are no reviews about it at all. But it is used in the creation of new varieties. Many varieties of Magnus Johnson, including Albina Plena, were created with its participation.
