It is native on my Central Texas land. I love this little plant. It naturalizes in a cactus garden very nicely. It is nice growing in a decomposed granite walk way or as a edging plant. It grows in solid caliche and improved catus soil. Its low stature makes it perfect to use with cactus and low growing prickly pear. It seems to always makes me smile. And I love all its names, from from the lyrical melodic Parralena and Dysodia to "Common Dog Weed"
