I thought this was the gardening forum. Where am I? LOL kidding misriv.
My SIL has one and so do I. Lots of sun, yes. Hers is in the ground and mine is in a pot. Neither of us covered them in the winter and they are fine. I like to dry my herbs & use that in the winter when I don't have fresh available. With the basil I could clip it every few days. The rosemary is a little slower growing so I clip it maybe once every two weeks for my dried stash. I place the herbs on a paper towel in my kitchen window until they are dry, about a week or so. They must be crispy dry before you put them in a Ziploc or you'll get mold. I doubt that is how you are supposed to do it but it works for me.
I like kids. They taste like chicken.
