More like 17 degrees below 0 C. Cold, but not that cold.
32 F is 0 C (freezing point of water), and C degrees are 9/5 the size of
F degrees.
BTW, 0 F is the coldest temperature reachable by adding salt to ice
in order to melt it (as in ice cream makers).
Gerry, with Mesmerizer soon to have more than one stalk in bloom
