Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

What is it with you and the curare and now mulberry sap? This is still out of our range of expertise and really off-subject for people interested in growing plants native to North America, which is our specialty.
