SproutRobot is a web service that tells you when to plant fruits and veggies in your garden and sends you seeds.
So it's good resource but even if you don't order from them you can enter your zip code and it will tell you what to plant and when.

I did it and it told me to start bell peppers and tomatoes indoors and even gave me instructions on how to do that.
I learned that as early had March 26th (or April 9th if you only look at things my family will actually eat) I can start planting things outside.
I can see where this will be helpful for someone like me who waits and waits for summer to come and then misses the window to plant certain things (peas 3 years out of 4).
