Please don't stain cherry, it's a beautiful wood and doesn't need you "helping" it (and be thankful I said please). After a little while the UV in sunlight will darken it, which you can slow down by applying UV inhibiting finishes. But, sheesh, why would you want to? I dunno, what's next? What's the best paint to use on walnut?!
Cheers, Jester
Who might have revealed a bit of a bugbear there...
