Crocuses - Sure Signs of Spring in New England

While I was walking around my parents' neighborhood, I spied some crocuses popping out of the ground. These are great flowers that we don't have here in the San Francisco area. I was thinking of planting some in my yard, but I believe they require the cold as a part of their initial growth. Oh well, they are one of the treats I get to see when I go back East.
