Art quilt for an auction

I'm a Master Gardener in Clark County.  We are just over 250 members, and we're all pretty active in the community.  This fall, we are planning to have a garden party to raise money to support our program.  We're going to have live music and a charity auction.  I was asked to donate a quilt, and gladly accepted.  I showed the planner some pictures of recent quilts that I can give them right away.  Hmm, they weren't exactly what they were thinking.  So, I told them that I would paint a bee on a flower and donate that.  I have until September to make the quilt, which should be easy to do.

Here are some of the pictures that I took that I'm considering:

What do you think?  Any favorites in this bunch?  Let me know!
