Sally, I used to just get the Dutch lily bulbs too, until Tracey showed pictures of some of her beauties. Some of the ones hybridized here in the US are so much better, the colors are wonderful, and they are bred for the garden, so they actually live longer here.
So try a few from the US growers. Like Faraway Flowers, The Lily Garden, or BD Lilies. I wish I could say BuggyCrazy. Believe me you will see the difference.
