Becky,
On the AHS Portal's "Hybridizing" forum, there is a discussion on what makes a daylily worthy of being registered. There are some good opinions on that thread. There seems to be a wide difference in not only what is registered, but what is offered for sale, and at what price. Some seem to me to be incredibly beautiful with great plant characteristics, while others seem pretty plain faces with not much branching or bud counts. So, I'd say if you want to register one of your flowers, go for it. It's that same price as 6 gallons of gas, but lasts longer. We figure in another few years that Doris and I will have something worth introducing, if we keep reading everything we can, and keep dabbing pollen. If not, we had fun trying! If we could just focus on one thing, instead of loving every form, size, and ploidy!!
