Title: Oaks at Wildflower Center from Wimberley TX
Answered by: Barbara Medford

QUESTION:

I know you have numerous Quercus fusiformis examples at the ladybird Johnson Wildflower Center. My question is, do you also have Quercus virginiana growing there? Also, is Oak Wilt a disease that has been around for thousands of years, or did it get brought in in recent times?

ANSWER:

From our Recommended Species page, there is a Master List of Arboretum Taxa and our Oak Collection, both of which include Quercus fusiformis (Escarpment live oak) and Quercus virginiana (Coastal live oak).

From Austin Tree Specialists, here is a History of Oak Wilt,  which should answer your question about where it came from. The answer is apparently that it has been around natively for a very long time, and just wasn't identified until more people came into some of the infected areas. We suggest you read all of Texas Oak Wilt.org for more information.
