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 do cedars do to cause cedar fever?
Answered by: Barbara Medford

QUESTION:

What do the native cedars in Fate Tx do in the winter that causes allergies to get really bad that they have named it cedar fever

ANSWER:

The native cedars, which aren't really cedars at all but  Juniperus ashei (Ashe's juniper), are just doing what all plants and animals are wired to do, which is reproduce. This article from Texas Monthly Ranch Cedar Fever explains it much better than we can.  We don't know if it will make you feel any better, but Fate, TX is not the only place this occurs. You share your discomfort with just about everyone within wind range of Central Texas, where the Ashe juniper thrives.
