Ask Mr. Smarty Plants

Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers Nan Hampton, Jimmy Mills and Barbara Medford to be the culpable and capable parties. Yet, others think staff members Damon Waitt, Joe Marcus and Philip Hawkins might play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.
