They are only hardy in zones 10-11, and you are in zone 6b, so they do need to be indoors till the threat of frost has passed. In my own garden, also 6, they will take a light freeze, but not a hard freeze such as 26 degrees F. You might lose your flowers, but there will be more. I don't think it will die at 32 degrees.
I hope you get moved so it can get back indoors!
