Siberian woodrose
A member of a little-studied morning-glory genus, the siberian woodrose is a rarely cultivated flowering vine. Its flowers are smaller and less numerous than its sister species, making it a rather unpopular choice in the garden. It does, however, attract a variety of pollinators, including hummingbirds and bees. Take care, however, as the seeds of siberian woodrose are poisonous if eaten by humans.
