I did what you did the first year too. Just used some stuff around to see if I could set seed and start some plants. HA! so easy!
Now, on the advice of Phil Reilly who said things like...
It takes just as long to grow a ho hum daylily as to grow a possible goodie! (here 2-3 yrs for bloom)
Buy the best even if it is just 2 or 3 and use them. Go for unique and distinction.
Don't cross what everyone else is using.
Get a daylily or more that have great plant habits and lots of buds and branching. It is easy to put a pretty flower on a great plant. It is not so easy to have a beautiful bloom and try to get buds and branching on it. How true!
Set a goal. Want tall? Want dormant? Want late bloomers? Like UF's?
If not buying a few of the best ($$$) that have some new gene pool, you could buy sister seedlings or seeds from a good hybridizing program that matches your goal.
Hope this helps.
