Compares the germination and growth of the invasive Ruellia tweediana to the native R. caroliniensis under wet and dry conditions. In general, light increased germination for both species. For R. caroliniensis, germination was highest 33 degrees C and 30/20 degrees C. Under wet conditions, R. tweediana had the greater dry weight increase, CO2 assimilation, and shoot nitrogen and phosphorus use efficiencies. There were significant species x moisture interactions for shoot and root nutrient content.
