protecting from early snowfall

I believe snow is a possibility for Saturday night.
What would be the best method of protecting one lonely flowering plant in the event of an early snowfall?

 

I think a tepee-type structure, made of sticks and plastic sheeting, would be cheap and effective.
Remove as soon as the snow stops.
You can also use this to help keep ground heat in somewhat.

 

thanks, I just hope the snow doesn't bring mean winds with it, so far she's withstood up to 50 mph wind with rain, so we shall see
