I went to the florasiam website. How do you know that they ship to the USA? The homepage states that they ship to Asia and the Oceanic countries and provide a plant inspection sticker from Thailand. You had better call them before you make an order. It is difficult to get bulbs into the USA since they need a Dept of Agriculture inspection sticker in order to be imported. So unless they are shipped as misc merchandise, the bulbs will be not get through customs without that document. Each country has different rules about importation of plant material.
