I keep an eye out for the first green tips of crocuses every year. They aren't typically, the first to show their heads - tulips might be, or even daylilies - but they are the first to bloom, so they are the ones I watch for. This year is quite late! Usually I find them around the 9th of March. But these lttle guys have been up for a while - our several March snowstorms just hid them from view.
