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: Plant identfication
Answered by: Nan Hampton

QUESTION:

Hi...Can you please identfy the tall, evergreen shrub with purple plum-colored foliage that I have noticed in winter locally?...Hope so, need he color! THX

ANSWER:

Well, Mr. Smarty Plants can tell you the native evergreen shrubs that produce red or purple foliage in the winter and the deciduous shrubs that have colorful fall foliage.  However, it is possible that the shrubs you are seeing are introduced and not native.  If none of the native shrubs that are listed below is the one you have seen, you can send us photos and we can perhaps identify it and determine if it is a native or non-native shrub.  Visit Mr. Smarty Plants' Plant Identification page for instructions for submitting photos.
