I know climbing plants in the Northern Hemisphere are twining clockwise whereas they twin the opposite direction
in th southern hemisphere (anti-clockwise)
However there is one excemption l know .
The cissus is twining anti-clockwise in the Northern
Hemisphere (here in Greece it does)
Is there any other plant that is not following the
general rule like cissus?
Thanks for replies
In Australia twiners we have imported from the northern hemisphere retain their clockwise twining habit. It's one way we can easily distinguish between the locals and the imports. I imagine that Australian plants (like your Cissus) grown north of the equator would retain their anti-clockwise twining habit, too. An exception, in Australia is the "Scrambling lily" , Geitonoplesiium cymosum, which is native to Australia but twines clockwise. Other members of its family (PHILESIACEAE) behave normally and twine anti-clockwise. I wonder whether the habit of the scrambling lily tells us something about its ancient origins??? Cheers, Trish P.S How is the Cissus doing, up there?
