Do plants feel the wind chill?

Like many on this site I expect, I am fearing how many plants I will lose this week. I have wrapped up those I can manage and know are at risk with fleece. Then there are those I simply can't, like the 20ft Bay which almost succumbed in the cold winter of 2012. The East side of the bush took fully 3 years to recover.

So this got me thinking about plant records and the minimum guide temperatures. Does -3C mean that, or do plants like humans feel the wind chill, which the Met Office here says is -12C this morning? I know many more tender plants don't like wind in itself. But does the 'feel like' figure reflect what they experience temperature-wise? Looking at the Echium I carefully wrapped, I can tell even without removing the fleece that it's dramatically shrunk in shape this morning, indicating sadly that the latter is most likely true.

    That's an interesting question, Jeremy: I have always assumed that plants "feel" the wind-chill temperature, on the grounds that you often find that one plant in a row, the end one, perhaps, suffers more than the ones in the middle.

    i wish i could get my act together to fleece things.

    I have concluded on the evidence of the plants in our garden that a wind chill of -12c is nowhere near as damaging as a true temperature of -12c. The Echium survived and is sprouting new leaves; and the Bay so badly hit the last time was completely unaffected. Slight problem with the sample size however. More research needed!
