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.

Please forgive us, but Mr. Smarty Plants has been overwhelmed by a flood of mail and must take a break for awhile to catch up. We hope to be accepting new questions again soon. Thank you!

Title: Donation of seeds of Silphium Terebinthinaceum to India
Answered by: Barbara Medford


Hi, I am located in India. I am planning to plant Silphium Terebinthinaceum in my garden in India. Please let me know who can donate me seeds to India. I need 20-30 seeds.


The Lady Bird Johnson Wildflower Center in Austin, TX is dedicated to the use, care and propagation of plants native not only to North America but to the area in which the plant is being grown. Silphium terebinthinaceum (prairie rosinweed) is native to 18 states in the United States and Ontario in Canada. That is the extent of our activity and expertise. We have no connections with anyone who might donate seed, and since the plant is probably not native to India, it could become a non-native invasive in your country, not a good thing.
