Tripterygium regelii

Tripterygium regelii - Regel’s threewingnut

This species is rarely seen but would be an excellent addition to the vine selection in the south of Finland. Without support, the threewingnut grows as a spreading bush, but given a tree to climb it can reach several metres, looking for light.

Threewingnut flowers in July. Although the individual flowers are small, there are so many flower corymbs that from a distance the vine looks decorated with white lace. The fruits have three wings, as the name suggests, which in autumn take on a strong red colour.
