A person who is passionate (i.e. slightly crazed) about their lawn, garden and outdoor decor.
We have all know at least one person who is like this. Every chance they get they are talking about the lawn and what they want to do next. My neighbor was a Yardiac - he would take Vacation days and brush each blade of grass with the proper amount of Lime.
