Ruellia angustifolia

The plant below is Ruellia angustifolia, or Mexican petunia.  It's also known as R. brittoniana.  As you may guess, it's not related to the bedding plant Petunia at all, it just has similar tubular flowers.  


Ruellia is an upright, stalk-forming perennial that grows in almost any condition, in areas of the tropics, as far north as Texas and Florida.   Its hardiness accounts for why this is considered a top-ranking invasive in Florida.
