Increasingly available in garden centers, exotic cuphea looks like the tropical native it is. It loves hot, humid weather and will bloom all summer, some types producing cool little tubular flowers in red-hot colors that give it one of its common names -- cigar flower.
It does well in containers, where you can baby it with rich, moist potting soil and keep it well-fertilized. Under these conditions, it will bloom nonstop all summer, as long as it gets water. Look for a variety of forms; some have curious bat-face-shape flowers; others are more tubular.
