Looks like you lucked out and purchased one of the Biltmore series oriental lilies or a fairy new cross named Orienpet. These are very large and tremendously fragrant lilies. I grow them and they do very well here in PA as a perennial bulb. Mine multiply and form large clumps that usually bloom in July and August. They do require a cold dormant period. I am not sure if they will come back for you in your climate. They may be just an annual bulb in Fla. They are long lasting as a cut flower also. Enjoy!
