Pruning

Although twin flowers reproduce through underground runners and spread easily, they are not considered aggressive and are often taken over by other plants. If you want to use them as ground cover, you should give them enough room to spread if you want them to multiply.

Native to Canada

Styling and Use

The twin flower likes shade to part sun. They make great ground cover in woodland gardens.

After the flowers have faded, the evergreen leaves stay on the plant over winter, underneath the snow.

History

It was named for Carolus Linnaeus (1707-1778), the father of modern botany, who liked the flower so much he had his portrait painted with it. He was responsible for naming of around 8,000 plants, as well as many animals and the scientific designation for humans: Homo sapiens. The naming of Linnaea borealis was not done by Carolus himself, but rather friend and teacher Jan Frederik Gronovious in his honour.
