Just a heads-up that daylilies and bearded iris will both need to be divided. My daylilies (which I am nuts about) need to be divided about every 4 years. I don't know what the time from for dividing bearded iris is. Both types of plants are gorgeous, with many varieties. But if you don't divide them, you will eventually have lots of green and much less flowers.
Hard to go wrong with daffodils. I have some daffodils in my garden that I planted in the mid-1980s. And they still faithfully come up every year. Hyacinths can also come back year after year, but in my neck of the woods (zone 7b), if I don't fertilize them, they either don't come back, or they come back as spindly plants with hardly any flowers. Crocus are also wonderful (and do multiply over time), but you'll need to plant a lot of them, since they are pretty small.
Mmm, just writing this has me already dreaming about next spring. The joy of gardening!
