Thank you so much for the info.. *Smile

As a machinist and with some metal experience, I find it interesting how the
tendril actually bends toward the curl.
A bimetalic strip, as used in a thermostat, will bend on temperature change
because on one side of the strip that metal will expand or contract faster
than that of the other.

I'm curious how it's effected in the plant.

Any info?

Much appreciation for your contributions.

Best regards,

Hi there...

Anyone know how or what mechanisim a tendril uses to know which way to
wind around a (wrot iron) support (post)?

There were 4 posts for this winding plant to use.

It wound around all four posts in the same direction. ?? Go figure?

Any help would be appreciated.

Best regards,

Stan-
