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.

Answered by: Nan Hampton

QUESTION:

In what part of the world is the marijuana plant native?

ANSWER:

The origin of marijuana, or hemp, (Cannabis sativa), was the Causcusus region of eastern Europe, India, and Iran but now can be found growing all over the world in warm to temperate regions. You can read "A Description and Natural History of Hemp" from the University of Texas Institute of Cellular and Molecular Biology.
