Ladino clover cold wilt

[agmantoo]

I am attempting unsuccessfully to determine what is the cold (lethal) wilt temperature of Ladino type white clover. I still have a lot of remaining clover forage that could be fed prior to a hard freeze hitting the foliage. Any help in determining this temperature is appreciated.

Temperatures in the upper 20's does not kill mine, it just rolls up but is not lethal. Colder than that will burn the leaves back but should grow back and not be dead.
