While walking around the garden this evening i stood looking at climbing beans and noticed that all 230 plants spiraled in anticlockwise direction, that got me thinking 'why do they spiral in the opposite direction to the weather systems here in the southern hemisphere', and then which way do plants spiral in the NH. Having looked up on line i found this explanation ( I have, however, seen the tips grow back on themselves, causing one layer in one direction and another layer on top in the other direction, so it seems environmental, not predetermined.). Ok, so what would happen if i turned a few beans the other way, will they develop an feeling of inadequacy and wish to return to the anticlockwise statutes qu??....... wow this is riveting gardening talk, but hey, anything to keep you northern hemisphere fella's entertained in your winter down time.

The real question is: can you change the direction the water spirals down your drain.

Every thing spirals the same no matter where you are, it just seems different because clockwise is backwards down there.

In my garden they also spiral anticlockwise. During early summer, if I am setting poles and wrap them around in a clockwise fashion, they either unravel, or they start from where they are, and go in their preferred direction. |

well there you go, that blows that theory. I asked the question on a NZ gardeners facebook page, this was one idea put up,(below) but it doesn't work for you guys up top because ya weather systems also spiral anti-clockwise
It seems that every gardener who's answered my question so far on the FB page all say there beans spiral anti-clockwise so i dont believe that theory i posted earlier that -'so it seems environmental, not predetermined'. Seems that it is predetermined. So what is the common denominator here between the NH & SH ??, the sun still rises in the easterly quarter.
Its got to be that maybe growing tips are following the sun and that it only applies to growing tips and not tassels on likes of peas, pumpkins and cyclanthera etc
What would happen if i grew some beans under grow lights but moved the light from left to right, would they spiral the other way...probably never know as i'm hardly likely to get that carried away.

I thought you were just being funny  but I think that little bit of info is mentioned either in Susanne Ashworth's or one of Carol's books. I'm a bit dyslexic and couldn't confirm which way beans spiral right off without one to look at. I do know if one isn't climbing and you try to wrap it up the pole you gotta go the way it wants or it falls back off. |

So, who is going to breed the first clockwise bean?

philagardener when you are inside of a tornado somehow the direction doesn't really matter! The Coriolis effect has not been shown to involve plants. In The Power of Movement in Plants Darwin put forth the idea that the spiraling (circumnutation) was the plant's response to gravity and light. But plant experiments in space have ruled out gravitropism. One theory that makes sense to me is that like people, plants have a 'dominant handedness' (chirality) in their spiraling. Although the majority of plants grow anti-clockwise, there are some that grow clockwise, and some have been noted to change directions as they grow.
