Floral Borders?

I have all the blocks and the rows sewn together for the 2-block quilt.  But now, when I put up the fabric I had planned to use, the darker blue,  I am wondering if the fabric is too "flowery" for a boy's quilt.  The blue color is perfect, a rich royal blue with spots of purple blended in.  Used for the star points, you don't notice the floral pattern too much, the floral design is all cut apart and it looks more like a Nature print as opposed to a floral print. Here is a swatch of the fabric (it looks lighter in this picture):

I have asked a lot of people for their opinions, and it's a mixed review.  Some just point blank said no, it's for a BOY, you don't use florals for a boy!  Some said, Use it, it's fine.  Boys like flowers, and true, some boys do.  But this is for Max, a 12 yr old grandson, Boy through and through! He plays 8th gr. football and he's still in 7th gr. for goodness sake!  Someone said boys don't notice details like that, and another said you can barely make out the flowers, so go ahead, use it!  Gahhh!  How to decide!?

So I auditioned a couple of fabrics.  The medium blue in the 9-patch (on the left), and the dark blue (floral?) in the star points (on the right..)  I have enough fabric to make borders from either.  Here's the audition:

I'm gonna have to think about this some more, but personally, **I** like the darker blue on the right...
