SnaPdragon Vine  Maurandella antirrhiniflora      
Delicate, snapdragon-like purple flowers grow on a trailing or climbing vine rather than an 
upright stem. Thrives in harsh limestone soils and rocky slopes, demonstrating remarkable 
drought tolerance. Its long blooming season and ability to spill gracefully over rocks and 
walls make it both ecologically resilient and visually unexpected.

SPiderWort  Tradescantia occidentalis
Found all across Texas, mostly in a prairie or open woodlands setting. It is usually upright, 
and can get quite tall where it’s happy. The blooms form in clusters at the tops of the stems, 
and open a few at a time for a long period of time. They can vary a lot in color, from pink to 
a very dark purple. Spiderwort does nicely in either a garden or a prairie meadow setting.
