Title: Information about a red-flowered Pavonia lasiopetala in central TX.
Answered by: Joe Marcus
Pavonia lasiopetala (Texas swampmallow), most commonly known as Rock Rose, is a native of Texas and Northern Mexico which typically bears pink flowers ranging from soft, baby pink to carmine rose. The flower color of Rock Rose is usually a very attractive hot pink. Since this is the only species of Pavonia commonly grown in Central and West Texas, this is probably the plant in your garden. A red-flowered Rock Rose would indeed be an unusual find.
Many plants bear flowers of colors different from the norm for that species. White-colored flowers are common on many species that normally bear flowers of other colors. The causes of color variations can be genetic, nutritional, or a result of pathogenic processes. Whatever the cause, plant enthusiasts often highly prize plants bearing flowers of a truly new color.
We have not seen a Pavonia lasiopetala with true red flowers. Such a plant would probably be quite valuable in horticulture. However, you should first ascertain that your plant is truly a Rock Rose. There are red-flowered mallows native to Texas that could easily be confused with Rock Rose. Please see our Plant Identification webpage for complete instructions on how to submit images for ID,
