The most Americans I have seen have been at the Lily Nook, in Canada. Go figure. A few years back Jungs (terribly rated on Garden Watchdog) locally here had them, which is much different than the mail order company as their products on site have been really great. The bulbs were true to name and average sized, no problems with virus or anything. Most of my Americans came from there.
What a great way to start out the morning, all of these lovely lily pictures.
