Dairy girls, if you have a Costco near you, you can be vigilant and check their bulb supply. They have have nicer and much better quality bulbs than the unnamed big box stores. The vigilant part is that their best bulbs sell out first; they actually seem to fly right off the shelves. Then you need to plant them asap.

Also, while it is not a true lilium, you might want to consider zantedschia lilies (calla lilies). The blooms last for a few weeks, the colors are beautiful and the blooms are probably very salable. However, they do not winter in zone 6a and would need to be pulled whereas lilies do not.

The black zantedeschias have dark stems and pretty foliage.
