Great picture, reminds me of my daughter (I have both a son & a daughter). I tried to get my kids interested in gardening but it never really caught on. Every child is different, try not to be too disappointed if her interests don't line up exactly with yours.
My kids do have a small interest in bats but I only developed that interest myself when the kids were about 11 & 9 (they are 20 & 17 now). My daughter & I were walking the dog the other day and she pointed out a bat to me and said "Look! A bat! Aren't you proud of me for pointing that out?", which made me smile. My son recently changed his major to biology at a school where they do a lot of research with bats, so who knows what may come of that.
Speaking of organic gardening, I started with that but now I have become quite fascinated with permaculture, and am turning my backyard into a "food forest". Here is a good introduction to permaculture (48 minutes):
