Real estate in the Garden District is famous for its canopy of oak trees lining its streets, and graceful mansions surrounded by lavish gardens. Protected by wrought iron fences with a history of their own, the carefully tended gardens are the crown jewel of the neighborhood. In the spring they fill the air with scents of sweet olive and honeysuckle and bougainvillea vines, crepe myrtles and hibiscus bloom in a rainbow of colors.
