Would atleast throw a light blanket of some sort over her, we did this with our tomatoes and it saved them, the wind did blow for a bit though, and it uncovered one tomatoe plant. That one tomatoe plant turned black and withered away. If its going to be a light frost you should be fine. I would also get a small container/2ltre pop bottle, fill it with hot water, not too hot though, just hot enough it does burn your hand. And place it beside the base of your girl, this will let out some heat. Make sure you do it when the sun is going down.
