When will the threat of frost be past?

We're all getting the urge to begin gardening, but of course plants (especially young plants) don't respond well to freezing or sub-freezing temperatures. The exact last day of frost can vary from year to year, and from area to area (inland areas will tend to see frost occur much later in the spring than areas close to the Sound). Statistics show the average last day of frost for Seattle (referenced to the University of Washington) is March 22nd, and the "safe" date for planting is April 15th.
