Every gardener makes a list of spring flowers during the dark days of winter, and looks forward eagerly to the first burst of spring color. Spring arrives at different times depending on where you live, but the sequence of blooms is similar in most places. With that in mind, now is the best time to start planning your gardening schedule.  There's nothing like a visit to your local garden center to find out what will bloom in your region and when. You're bound to find old favorites and perhaps a few types of flowers you've never seen before.
