Hops
I've been told that hops will twine in different directions as they climb
upwards according to which hemispehere in which they grow. I'm in the Southern Hemisphere and my hops twine clockwise around supports. Every single one of my stems is growing clockwise with not one counter clockwise grower. Has anyone in the Northern Hemisphere noticed which way hops twine where they live? |

Janet The direction that climbers twine is controlled by their genetics. Some, e.g. hops, climb from right to left, but the majority, e.g. beans and bindweed, climb from left to right*. Nothing to do with which hemisphere they grow in, or the direction of the sun's travel across the sky, as many seem to think. * http://encyclopedia2.thefreedictiona...Twining+Plants The way water spirals on going down the plughole has nothing to do with the hemisphere it's in, either, but everything to do with eddies set up in the basin or bath when the plug is pulled out, and/or subtle differences in plughole design etc. See below for further info. https://en.wikipedia.org/wiki/Coriol...bs_and_toilets -- Jeff |

Working off your cite as a base, I've since found out that this way of twining is called dextrorse and twining in the other direction is called sinistrorse. (And Janet, you will no doubt realise that I'm now going to spend too much time watching which way down the various domestic plugholes the water drains. As if Spring chores weren't keeping me busy enough at this time of year.........) ;-)) |

But the Latin roots of the words are correct. Dexter means right-handed and sinister means left-handed. I'm not sure what adjectives can be derived from those nouns in the context of twining plants; probably something like "dextral" and "sinistral".

Chambers definition of Dextrorse "rising helically and turning to the left, crossing the observer's field of vision from left to right upwards". The OED gives a similar definition; "rising toward the right, esp. of a spiral stem". That'll teach me to be a bit more careful! David -- David Rance writing from Caversham, Reading, UK |
