Detective C's First Mystery: Surprise Sunflowers

A handful of sunflowers have popped up in my grandparents' backyard.  I was discussing with C how Grandma said she hadn't planted them.  I asked C if she could figure out how they got there.  It was so neat to see C's logic and thinking skills in action.  After she figured it out, she wanted me to record her answer to the Surprise Sunflower Mystery.  =)
