Miami is a city of immigrants, including the leafy kind. Early pioneers David and Marian Fairchild planted and grew many exotic plants, but it's a Madagascar native that has given Miami so much local color. The royal poinciana is a large, lovely tree that turns fiery red in early summer. Its blossoms are so intoxicating that for the past 68 years, Miamians have honored the royal poinciana with its own festival. Highlights include a trolley tour, luncheon, and a peek at the Fairchilds' historical home, the Kampong. It ends with the crowning of the Poinciana Queen. This year's fiesta falls on June 11.
