Daylilies aren't bulbs but they are great to incorporate in beds of spring bulbs. I was in your boat this/last year and once my bulbs played out, the daylilies picked up the torch and bloomed all summer. Now, we'll see how much the summer watering affected my spring bulbs (ie rotted) but I've accidentally dug up a lot of said bulbs lately and they look like they are all ready for another round.
