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: What trees in Austin right now have yellow leaves that are falling?
Answered by: Jimmy Mills


Right now there are trees in Austin that have bright yellow leaves. Do you know what trees native to Austin turn a very bright yellow in November? It looks like now the leaves are starting to fall off. Thanks


There are several kinds of trees in Austin with bright yellow leaves right now, so if you have photos that you could send to Mr. Smarty plants, we can provide a more satisfying answer to your question. Please follow the instructions on the Plant Identification page.
