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.

What are the native plants in Kerrville, Texas?


I can guide you to a source that will produce a list of a large number of the native plants of Kerrville/Kerr County, TX; but it would be very difficult, if not impossible, to assemble a list of all the native plants that grow there.  Here is how to get a list of the native plants that have been reported as occurring in Kerr County, Texas by the USDA Plants Database: 

Go to the USDA Plants Database.  Select "Advanced Search" from the Search menu on the left side of the Home page.  On the "Advanced Search and Download" page under Part A:  PLANTS Core Data choose "Texas:Kerr" under "County Distribution" in 1.  Distribution.  In 2.  Taxonomy put a check in the "Display" box beside "National Common Name".  Next, under 3.  Ecology select "North American Native" under "Native Status" and put a check mark in the "Display" box.  Scroll down to the end of Part A (just before the beginning of Part B:  Characteristics Data) and click on the yellow box that says "Display Results".  

This will give you a list of ~570 North American native plants that have been reported as being found/collected in Kerr County. This won't be a complete list of all the native plants in Kerr County, but it is a pretty good start.  The USDA Plants Database get their data from several sources, e.g., records of specimens of the plant in internationally recognized herbariums; publicly available published literature (preferably peer-reviewed) such as scientific journals, floras, masters theses and doctoral dissertations; and verified records from interested individuals.  You can read the Standards for Contributors that must be met in order for a plant record to be added to the database.

For a shorter list of the more common wildflowers in Kerrville, you can find a Wildflower Check List on the web page of the Kerrville Chapter of the Native Plant Society of Texas.  The list includes links to photos of many of the species.

Certainly not all plants that are native to Texas are also native to the Kerrville area, but there are several sources that cover all vascular plants, both native and introduced naturalized plants, in Texas.  They are:

If you wanted to take the time and effort, you could go through the maps in the two volumes of the Atlas of Vascular Plants of Texas and note those species that occur in Kerr County.   I would imagine that there would be approximately 570 plants—perhaps a few more because the publication also includes naturalized plants.  The sources used to compile Dr. Turner's list are similar, if not identical to those used by the USDA Plants Database.
