FYI, if you send the lily seed to anywhere in Europe or Canada (and many other places around the world), and enclose it in a regular envelope (not a bubble envelope). and as it is still under an ounce, it will only be 98 cents from the U.S. This way you don't have to claim its contents with the special form that you need with a bubble envelope or package. The USPS has 98 cent stamps especially for this. Just put the seeds between a Christmas card, birthday card, thank you note, or something of similar paper weight. That is all the protection they need (but maybe not so for other types of seed).
