Can my non working spouse have own HSA account?

I saw in TT the question if my employers HSA contributions were put into my wifes HS account. I always thought only I could have HSA account and that contribution limits were family limits? Anyhow, my wife does not work anymore, she is on my employer medical plan (high deductible) - can she have an additional HSA on her own, so we can put more money aside for medical cost?
