I'm starting to wonder what I might want in my flower boxes next year. Specifically, I'm wondering if there's a way that I can plant a few different things in there in the fall and have things that come up in the spring and flower at different points throughout the summer. I think I didn't phrase that well, but hopefully you know what I mean.

Is that possible?

Oh, and my balcony is fully in the sun. One window box gets a little shade towards the end of the day, but the other three are in direct sun almost right from sun up to sun down.
