» Life History
Plants found in association with Johnston's frankenia include saladillo (Varilla texana), tornillo (Prosopis reptans), blackbrush acacia (Acacia rigidula), guayacan (Guaiacum angustifolium), seepweed (Sueda sp.), gray coldenia (Tiquilia canescens), Drummondï¿½s jimmy weed (Isocoma drummondii), and whorled dropseed (Sporobolus pyramidatus) among other species. Saladillo and Johnstonï¿½s Frankenia often, but not always, occur together, and are frequently the dominant species in these areas because they are better able to tolerate the high salinities in the areas. Johnstonï¿½s Frankenia has been found at elevations ranging from 250 feet to 2500 feet above sea level.
Johnstonï¿½s Frankenia grows on vegetated rocky hillsides or saline flats. It is found on saline sandy or clay soils composed on average of 10% gypsum.
Movement / Home Range
Johnston's frankenia populations occur in Starr, Zapata and Webb counties, Texas and are known from Nuevo Leon and Tamaulipas, Mexico.
Flowering follows rainfall events throughout the year. The flowers are white with a yellow center and have 5 petals. Potential pollinators including flies, bees and butterflies have been reported to visit Johnstonï¿½s Frankenia flowers.
Johnstonï¿½s Frankenia may be up to 11.8 inches (30 centimeters) tall and 5.9 to 23.6 inches (15 to 60 centimeters) in width. It has a woody taproot and several ascending or recurved stems. The leaves are Â¼ to Â½ inches (0.6 to 1.3 centimeters) and are oblong with curled margins. The leaves have small, dense, grayish-white hairs on the underside where salt crystals are often visible. The plant turns from grayish-green to crimson red from November to February or under drought conditions
