With spring in the air, local gardens, nurseries and botanical gardens are showing off their latest acquisitions, and homes are opening their doors and gardens to the public. The variety includes one day tours or festivals, and others are self guided tours offered  throughout the year. Here are our nine picks ranging from  the annual Miami Villagers Garden tour and the white perfumed gardens in Key West to a “Secret Garden Tour” in Fort Lauderdale, and a blanket of bromeliads and a trove of topiaries in Miami. Together with  a panel of plant experts and demonstrations at Gardenfest! in Vero Beach, and more, flowers and gardens are erupting in a burst of color and fragrance.
