I saw your Mexican Petunia question in the FAQs. It helped a little but I need to know if there is any special care needed such as pruning, fertilization, etc. Will it survive a winter in Central South Carolina and how much water?

Commonly called the Mexican Petunia, Ruellia brittonia is an evergreen shrub that grows in full sun or light shade. It grows to 3 feet, with narrow leaves and 2-inch blue flowers. 'Katie' is a dwarf cultivar. It takes moderate water once established. Fertilize once a year at the beginning of the growing season with a balanced fertilizer such as 10-10-10. It looks better with a natural growth habit, so only light pruning to clear dead branches, etc. should be needed. It should survive your winter, but protection from potential frost is always a good idea. Thanks for writing!
