    I have a guestion for you. I started some Eryngium from fresh seed this fall (Sept) and they have germinated very well. They are outside in my unheated greenhouse.
    I am guessing that there will be a problem with them if I should get freezing temps?
    Not sure if they will survive or if I should should just bring them in if temps. are to drop severely? I am not asking for promises on survival, just any educated ideas.
    Thanks for any ideas.
    (Saved some seed for spring sowing)

    If I am not mistaken, sea holly dies down in Autumn, to spring back up in late winter, but not exactly sure. I wouldn't let it freeze in a pot nonetheless.
