Hi Casey:
It's definitely a tropical lily for two reasons 1) as Sue was asking the leaves are jagged, which is one characteristic of day tropical lilies versus Night Tropicals that have sharp tips, i.e. see the subtle wave picture 2. the second reason it is a blue (purple) lily that was only available in tropicals until recently (not commercially yet, blue hardies. As far as further identity I would not go further, since there are a lot of hybrids this could be. Rather you should call it my pretty purple lilly.
